After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Have tried many times in the forum to get help with this issue to no avail... After prodding a bit, it seems to be a somewhat common issue with internet working intermittantly and then needing to be reset. This is followed by the network card thinking that there are other networks in the area with names similar to mine but with odd spelling variations that include asian characters, etc. Here is the description of the issue. Below it are the code entries and responses for the general info:
Started with 10.04. Had a Linksys E1000 wireless router. Was told I needed to buy a Penguin Wireless N USB Adapter (actually an Atheros card.) off of the ThinkPenguin website. I did, but I couldn't get things working until 11.04 came out. After that all issues were solved and things worked great. When 12.04 came out, I thought about upgrading and the problems it could create, but finally figured it wouldn't be the Ubuntu Team's plan to move backward, so I upgraded. Things worked fine for a little while and then web pages stopped loading.
If I reset my internet connection in the Ubuntu menu in the upper right hand corner (I log off, then log back on) things work fine again for a good 10-15 minutes.
It would seem that this problem occurs faster on sites that are trafficing more info, for example, it takes a youtube video about 5 minutes to stop loading, or I simply open another youtube video at the same time and the browser cannot connect to it until I reset the connection. A regular site containing only reading information with limited animation doesn't give me trouble as fast. As I am typing this I have 2 other sites open containing only readable info, and yet I am having no issues navigating the forum, but eventually I will have to reset the internet connection.
The people at ThinkPenguin seem to think the wireless card is malfunctioning, and that it isn't a result of the new upgrade to 12.04. They also said that the card I bought from them gets more complaints with my modem than its cheaper sister version, the Penguin Wireless G USB Adapter. I bought the Wireless N Adapter(atheros) because they initially told me it was faster than the Wireless G Adapter and was only $10.00 more. Now I'm being told to buy the cheaper one too. That's a bit annoying, so I figured I'd check the forum before shelling out more cash. It isn't a lot of money, but I'd still like to know a little more before I buy another Wireless card.
Updating the package files? It doesn't finish doing so, althoug it seemed to help a litlle, in fact, restarting the system usually helps a little but eventually the internet stops and I have to turn the wrieless off and on again.
please explain how to fix this if you can...

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
@ TMundo,
Please make it a habit to post the outputs of commands within [code]<put the output code here>[/code] tags. This not only preserves the formatting, but also prevents certain parts of code from turning into smileys, and puts the code in a nice box with scrollbars making the post neat and more readable.
To do so just click on # at the top of edit box to auto-generate those tags, then copy or cut-paste the output codes in-between the tags.
(Please do it now by editing your post, in advance mode, or by manually adding those tags in the beginning and end of outputs)
Onto the problem.
You already seem to have the correct driver for the chip (carl9170). However, as per Linux Wireless website, you "may" need to manually get the correct firmware (http://wireless.kernel.org/en/users/...ar9170#caveats).
So please follow the above link to get the details, and go to the "official device firmware" section (it is closed-source, but 'ready-to-use' official fw from atheros) to get the correct firmware for your adapter. Then copy (overwrite) them to you /lib/firmware/ directory (those already existing must be the open-source versions, and may be suffering from some bugs yet to be rectified).
Reboot, and hope for the best. Good luck!

Okay, a few issues;
1. In the link you provided the:
one stage: adds support for AVM FRITZ!WLAN USB Stick N and AVM FRITZ!WLAN USB Stick 2.4: ar9170.fw
was listed as: 404 Not Found
Is there another site where it can be taken directly from atheros or somewhere else?
2. I got the files listed as:
two stage: legacy firmware
ar9170-1.fw, ar9170-2.fw
I copied those over the original ones and (although they claimed to copy %95 for the first one and %100 for the 2nd) I got this message:
Code:
ar9170-1.fw: Error opening file '/lib/firmware/ar9170-1.fw': Permission denied
ar9170-2.fw: Error opening file '/lib/firmware/ar9170-2.fw': Permission denied
I can't undo the overwrite so I will restart and see what happens so far.

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
TMundo,
A big sorry for being an utter stupid and sending you in the wrong direction.
I just realized that this driver (carl9170) doesn't use those firmware at all! It uses carl9170-1.fw, which again, already exists in the default packages. But before trying anything else, I think you should read this page thoroughly, especially if you are going to use n-channel, as the compatibility and performance of this particular chip is not very promising - to say the least. Some excerpts:
Quote:
Users should be aware that these devices might go mad from time to time. Because these BUGs seem to occur too randomly to be identified, but happen often enough to be really annoying, the firmware and driver come with some convenient features to keep the overall downtime at a minimum and without requiring any user intervention. But as mention before there is a caveat: The user has to setup everything properly!
..
..
It's worth mentioning that the chip was designed, produced and sold in the early 802.11n-draft period. Compatibility will always be an issue.
..
the device is not suitable for any serious 802.11n setup.
If you wish to try the firmware provided on that site (there's a minor size difference, so i assume it is different from the one already existing in /lib/firmware), please backup the current one:
Code:
sudo modprobe -rfv carl9170
cd /lib/firmware
sudo mv carl9170-1.fw carl9170-1.fw.bak
then download this one from the same page: http://linuxwireless.org/en/users/Dr...=carl9170-1.fw
Copy it to your /lib/firmware directory:
(assuming the downloaded file is in your 'Downloads' directory)-
Code:
cd Downloads
sudo cp carl9170-1.fw /lib/firmware
and reboot. Afterwards, as recommended on the same page, load the driver with nohwcrypt=1 parameter:
Code:
sudo modprobe -rfv carl9170
sudo modprobe -v carl9170 nohwcrypt=1
Then try to connect. If it seems better this time, we'll make it permanent.
-
Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
That's okay, because when I copied the two files into lib/firmware
two stage: legacy firmware
ar9170-1.fw, ar9170-2.fw
I basically overwrote the existing ones of the same name, and even though it said there were errors, when I reset, everything seemed to work right. We will see if it stops in the next few days, I was able to update about 512 update files which have been building up over time. strangely 17 of them would not update, I have to investigate this issue further. I don't know why overwriting two files you said were the wrong ones would cause it to work better unless it reset some kind of glitch.
Unless it's only because I reset the computer that it seems to be working, in which case it will eventually stop working I will keep an eye on it the next few days
Thinkpenguin later informed me that the Wireless N is difficult to work with, (shrugs) they didn't tell me that when I first bought it.
Let me see what happens over the next few days and I'll let you know if it stops working again. If it stops I will try your other directions.
-Thanks for your help

Umm.. a bit confusing to me also but the result of:
clearly shows that it uses only carl9170-1.fw firmware.
Since that firmware also pre-exists in the /lib/firmware directory, I think it's just a matter of chance that it got connected.
I guess it's time to search for a command to figure out the firmware in use ;)

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
looks like it finally went back to it's old behavior, it took some bit of time, but it eventually did. I will try the next step you posted and let you know what happens.
-
Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
If you wish to try post #9, then in order to make the nohwcrypt=1 parameter permanent, do this:
Code:
echo "options carl9170 nohwcrypt=1" | sudo tee /etc/modprobe.d/carl9170.conf
If it doesn't seem to help, you can simply delete the /etc/modprobe.d/carl9170.conf file, or just comment out the line by adding a # in its beginning :
Quote:
# options carl9170 nohwcrypt=1

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Okay:
I downloaded the carl9170 and installed it following your directions. It is still giving some intermittant trouble but seems to work much longer. It always seems to work long after I reset the computer, so I'm not sure if the firmware made it operate a bit longer or or not. It's hard to tell how much time I'll get out of it before it malfunctions, but I gues the point is, it still malfunctions eventually.

I will wait until it stops working to post the rest of the code response you gave me.
Which is, (for anyone else who is reading this:)
Code:

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Hmm.. here's my latest finding : http://ubuntuforums.org/showpost.php?p=12305169
Accordingly, I think you should try 12.10 using a live cd/usb and test it for stability of wifi (+ other things). If it really proves to be as stable as the post states, consider doing a fresh install of 12.10 on your system (to avoid carrying any misconfiguration from the current setup).
Apart from above, two other things come to mind which you can try beforehand.
1) Since you are not using high speeds anyway, try disabling the n-channel in your router.
2) Try disabling IPv6 by adding the following lines to your /etc/sysctl.conf file :
Quote:
# force-disable IPv6
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
To do it quickly, you can just copy-paste the following command in terminal:
Code:
echo -e "\n# force-disable IPv6\nnet.ipv6.conf.all.disable_ipv6=1\nnet.ipv6.conf.default.disable_ipv6=1\nnet.ipv6.conf.lo.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf
Reboot and check the connection stability.
If neither these nor the new 12.10 solve the problem, then I guess it's time to honour the warning I quoted earlier in post#9, and get a better supported card :(
Fingers crossed, awaiting the result of this 'last' shot..[-o<

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
hmmm, I haven't tried the latest instructions yet, because I was waiting for the connectivity to stop. so I could give you the results of
Code:
dmesg | grep -e wlan -e carl9170
want to give you as much info as possible.
However, connectivity did not stop for the next three days. I was waiting with the command pasted in the terminal so I could run it as soon as connectivity stopped, but after a day or so I must have closed it. I'm sure I reset the computer at some point as well. Anyway. This time I will keep the code more handy.
As for the:
Code:
echo -e "\n# force-disable IPv6\nnet.ipv6.conf.all.disable_ipv6=1\nnet.ipv6.conf.default.disable_ipv6=1\nnet.ipv6.conf.lo.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf
I would like to give you the info from the other code first (when connectivity stops) unless of course one issue has nothing to do with the other. Should this not work, is there any way to reverse it? (should it not connect at all.)
Also, now that the carl9170.fw is installed, even though it is not permanent, does that mean... well, what does 'not-permanent' mean exactly? It doesn't go back to the original settings after a reset, does it?

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Okay, the plot thickens
When connectivity stopped, I entered:
Code:
dmesg | grep -e wlan -e carl9170
and the output was:
Code:
[ 21.994656] usbcore: registered new interface driver carl9170
[ 22.645723] Registered led device: carl9170-phy0::tx

Also, it must be noted, and this is very strange, after I had finished copying and pasting the code into Libre Office, and prepared to reboot the computer or unplug the card, I went and refreshed one of the pages that wouldn't load when connectivity halted, and voila, all of a sudden connectivity was working again. I don't know if and when connectivity stops, whether it is only for a few minutes, or whether it is for much longer, because in the past, I never really went to do another task on the computer when connectivity would stop, I would simply pull the card out and then plug it back in. Don't know if this gives us any more useful info.

Run the code to switch of IPv6. Set to 'Ignore' in Network Manager also.

Yes, we always can revert the changes we make. That said, IPv6 is still used very rarely, so it is okay (or sometimes even better) to leave it disabled (of-course unless it is the one that is being used for connection in your router - which is, as I said, still a very rare case).

'Temporary' is the parameter (nohwcrypt=1) that you are using with the carl9170 module, not the firmware file (carl9170.fw). It is just a file which is there now, and is permanent unless you (or an update) replace it with the backup or a new one. Also, even the parameter is permanent if you have put it in the '.conf' file as I wrote earlier. But making that parameter permanent is of no use (or may even be harmful) if it is not helping the stability.

^That behaviour can be (not necessarily though) caused by unnecessary IPv6 requests while the actual connection is IPv4-only. Accordingly, please try what Bucky Ball suggested above (that is- disable IPv6 as I suggested, then also set it to 'Ignore' in NM).

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
okay, executed that command, and switched the setting to ignore, will see what happens, thanks guys!
-
Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Okay, nope, we are back to square one, still the same behavior, although I must admit, everything I tried that you all suggested seemed to make things run better and for longer, but that may just be the fact that I reset the computer each time. Reseting the computer always makes the wireless run uninterrupted or longer periods.

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Hi,
I consulted a much more knowledgeable senior of mine and he immediately caught a very big mistake I made -

It should have been "options carl9170 nohwcrypt=1". I feel really embarassed how I made that mistake (not that I don't do it often, but that I got caught in clear daylight.. :D), and how I kept overlooking it for so long.
Please correct it immediately. You can do it in one step by (you may simply copy-paste in terminal) -
Code:
sudo sed -i 's/^nohwcr/options carl9170 &/' /etc/moprobe.d/carl9170.conf
If doing this alone doesn't help, there is another advice based on dmesg indication in your very first post -
Quote:
[201772.688413] ieee80211 phy0: rx stream does not start with a first_mpdu frame tag.
To take care of above, please try (only if the above correction doesn't help)-
Code:
sudo modprobe -rfv carl9170
sudo modprobe -v carl9170 noht=1
If it seems to help, we can include it in permanent options.
And.. there is yet another advice to try 'G' channel in your router instead of 'N', plus make sure the encryption is set to WPA2 only, not WPA/WPA2 mix mode.
Let us hope for miracles this time, but to be honest, the only person I could find happy with this chip was the poster of this post I linked to earlier. I hope you become the next one!

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
After entering code:
Code:
sudo sed -i 's/^nohwcr/options carl9170 &/' /etc/moprobe.d/carl9170.conf
Output is:
Code:
sed: can't read /etc/moprobe.d/carl9170.conf: No such file or directory
Not sure why, but I assume that didn't work (shrugs)
So I input the other codes:
Code:
sudo modprobe -rfv carl9170
Output:
Code:
rmmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko
rmmod /lib/modules/3.2.0-24-generic/kernel/net/mac80211/mac80211.ko
rmmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/ath.ko
rmmod /lib/modules/3.2.0-24-generic/kernel/net/wireless/cfg80211.ko
Code:
sudo modprobe -v carl9170 noht=1
Output:
Code:
insmod /lib/modules/3.2.0-24-generic/kernel/net/wireless/cfg80211.ko
insmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/ath.ko
insmod /lib/modules/3.2.0-24-generic/kernel/net/mac80211/mac80211.ko
insmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko noht=1
With the second codes, after the first line it shut the wireless off and after the second one it turned the wireless back on again. We will see what happens in the next few days.
Thanks again

Which means either the file was not created at all, or it might have been mis-named. To confirm, please post -
Code:
ls -l /etc/moprobe.d/
[Edit : repeated typo. It should have been "modprobe", not moprobe]
If it is not there, we can create it now with the correct command this time (you may copy-paste commands to avoid errors) -
Code:
echo "options carl9170 nohwcrypt=1" | sudo tee /etc/modprobe.d/carl9170.conf

Had the .conf file been in effect, the above line would have looked like -
Code:
insmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko nohwcrypt=1 noht=1
Which is what I was expecting. As per the description on linuxwireless.org, the nohwcrypt=1 option is more important. So please create the .conf file as suggested above, then retry the last two modprobe commands to see if it goes as expected. I doubt if the noht=1 option alone can make it any better.

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Okay:
I confirmed that the file is not there
After:
Code:
echo "options carl9170 nohwcrypt=1" | sudo tee /etc/modprobe.d/carl9170.conf
There is no output
I then ran:
Code:
sudo modprobe -rfv carl9170
and got output:
Code:
rmmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko
rmmod /lib/modules/3.2.0-24-generic/kernel/net/mac80211/mac80211.ko
rmmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/ath.ko
rmmod /lib/modules/3.2.0-24-generic/kernel/net/wireless/cfg80211.ko
Wireless signal shuts off:
Then I input:
Code:
sudo modprobe -v carl9170 noht=1
Output is:
Code:
insmod /lib/modules/3.2.0-24-generic/kernel/net/wireless/cfg80211.ko
insmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/ath.ko
insmod /lib/modules/3.2.0-24-generic/kernel/net/mac80211/mac80211.ko
insmod /lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko nohwcrypt=1 noht=1
so it looks like the: nohwcrypt=1 is in there, however after putting in the command:
Code:
ls -l /etc/moprobe.d/
The file is still not found, I then realized there was a typo in the code,
so I entered:
Code:
ls -l /etc/modprobe.d/
not really sure if the .d is supposed to be there or if it is part of the typo, but the results were:
Code:
total 44
-rw-r--r-- 1 root root 2507 May 5 2011 alsa-base.conf
-rw-r--r-- 1 root root 325 Jun 15 2011 blacklist-ath_pci.conf
-rw-r--r-- 1 root root 1603 Jun 15 2011 blacklist.conf
-rw-r--r-- 1 root root 210 Jun 15 2011 blacklist-firewire.conf

-rw-r--r-- 1 root root 127 Apr 22 2012 dkms.conf
-rw-r--r-- 1 root root 30 May 18 2012 vmwgfx-fbdev.conf
and so, it looks like we are now getting somewhere, although I am not sure where.
it is also necessary to note that even though the previous time I entered the two modprobe codes the file was not even there, connectivity was still running uninterrupted for a few days, I now beleive this is regardless of reseting the computer. Whenever we try to mess with it in the manner we have been using, it seems to jolt the system in such a way as to make the connectivity work uninterrupted for about 3 days. Not sure if this info is pertinent, but it seemed worth mentioning. As usual, will see what happens in the next few days.
Thanx again

Re: After upgrading from 11.04 to 12.04, Wireless works intermidantly...
Hmm.., looks like I'm on my way to create some kind of record of 'Making Typos' this month ! Funny and embarrassing at the same time. I wonder if yet another sorry is sufficient.
Anyway, now that it's fixed, I'd prefer to shamelessly move on.
Although this sounds a bit odd to me -

Well, I just copy-pasted the above command to verify, and I did see an output - "options carl9170 nohwcrypt=1".
So I think that string would have appeared on the terminal, you just didn't notice it. Although it doesn't really matter if the string is returned or not on the screen as long as it is written correctly in the target file, but just for your info, this is how 'tee' command works. It both displays the supplied string on the terminal, AND drops it in the target file.
But anyway, we don't need to worry about it since the output of modprobe -v shows that everything has been done correctly this time -

Oh, one more thing, not very important though -
Quote:

It IS supposed to be there. The 'modprobe.d' is a directory we had to put the .conf file in.
By the way, now that you seem to care about these things (and I'm getting worse on typos), may I give you a tip to avoid some mistakes while typing commands or addresses (and make it easier too!) -
While typing a command, just type a few initial characters, then press 'Tab' key. The rest of the command will be auto-completed. Same goes for typing addresses. For example, if you only type -
/et
and press 'Tab', it will automatically be completed to -
/etc/ (because terminal knows there is one and only one object at location '/' that starts with 'et', and that it is a folder - "etc")
Now after /etc/, type only "mo" like this -
/etc/mo
and press 'Tab' again, it will auto-complete to -
/etc/modprobe.d/ (because again, there is one and only one object in "etc" directory that starts with "mo" and it again is a folder)
Again, if immediately after that (where the terminal's cursor is - waiting for more input) you type "ca" and press 'Tab' I hope you've already guessed what will happen :) Of course, it'll become -
/etc/modprobe.d/carl9170.conf (unless there are more than one objects that start with "ca")
But this time the terminal's cursor will also put a 'space' after the completed address. Why?? Because it knows that carl9170.conf is a file, and so you can not go "into" it.
But it does expect that you may want to type another filename or a command option or a parameter 'After' the filename, which are things that are typed after a space.
But if, after /etc, you type "de" and press 'Tab' -
/etc/de
Nothing will happen, although there is a directory named -"default". Why?? Because there is another directory in /etc/ that starts with "de", that is - "depmod.d". So you'll have to type more characters until it becomes a unique pattern to look for. In this example, typing just one more character "f" is sufficient -
/etc/def
press 'Tab' and you'll have /etc/default/ auto-completed on your terminal.
If you don't know how many files/directories/commands exist that start with the pattern you have typed so far, just press 'Tab' twice. Unless they are in hundreds, terminal will immediately suggest you the available options by displaying them in a new line/paragraph, and will again return in a new line to wait for your further input. Like this -
:~$ /etc/ap
apache2/ apm/ apparmor/ apparmor.d/ apport/ apt/
:~$ /etc/ap
where -
* the first line was when you pressed tab (twice),
* the second line is available options that the terminal suggested to you,
* the third line is where terminal immediately moved its input prompt after suggesting the available options, waiting for you to type more characters.
However, if by mistake you type -
/etc/mop
and press 'Tab', guess what....... Nothing will happen, no matter you press 'Tab' two times or two-hundred times. Why ?? Because there is nothing at location /etc/ that starts with "mop" !! And so you immediately realize - "Eureka !! We have a T-Y-P-O..! :D"
Hope that compensates the yet another typo on my part
(Phew....!! Mommy ! A glass .. BIG Jug of water please..!!..)
If the connection gets finally stable this time, we can really consider it a great achievement - given how disheartening the driver/chip's description on linuxwireless.org was -
Quote:
Users should be aware that these devices might go mad from time to time. Because these BUGs seem to occur too randomly to be identified, but happen often enough to be really annoying, the firmware and driver come with some convenient features to keep the overall downtime at a minimum and without requiring any user intervention. But as mention before there is a caveat: The user has to setup everything properly!
Shall very curiously await your feedback, hoping for the best !
