Having problems with my wifi connecting to any websites that require username and passwords including ubuntu forums. Also having problems with yahoo, hotmail, gmail, youtube etc.,etc.. What exactly happens or not?

Is the firewall interfering?
sudo status ufw

[zlyspl]

Hmm, I am not sure why r61pci is loading. in cat /etc/modules, the only thing listed are lp and rtc.

I would like to confess that I am using Broadcom 802.11 Linux STA wireless drivers from bcmwl-kernel source even though I am not sure if it is compatible with my wifi. However if I do not use this, I unable to connect to any wifi.

When I try to connect to hotmail, enter my usrname and password, I keep getting ERR_Connection_RESET. When I try to login to ubuntu, I get ERR_EMPTY_RESPONSE, when I go to yahoo.com website, it takes forever to load and when it finish, there is broken flash and all links are on the left hand side.

[chili555]

I think that rt61pci and its conflicting 80211 system is part of the problem. We need to find out how it is getting loaded and stop it and reboot and then, if needed, troubleshoot from there. May we see:
ls /etc/modprobe.d
cat /etc/rc.local

Also when I try to reply to posts here in Ubuntu, even though I typed in a lot more than 1 char's using my laptop, it still pops up saying I need to type more than 1 char to post. Sometimes when I post with code quotes, the code does not appear in the code box just a blank code box shows.

[varunendra]

Sometimes when I post with code quotes, the code does not appear in the code box just a blank code box shows.

Happening here with me as well since this morning (now is 8:10 pm). This is most probably happening due to the server sync issue that we were notified about a few days ago - something like "..in the process of changing server layout, users may experience a few minor glitches/problems due to the delay in the syncing of the two forum servers - bilberry and lingonberry.."

There are other problems like unintentional multi-posting as well, I hope it's all just temporary issue that will solve itself as soon as the forum layout change is finished.

By the way, posting just to keep track of the original issue about wifi, not to discuss the above ones. ;)

[chili555]

I see no other reasons that rt61pci is loading. Is there a listing for it here?
cat /etc/udev/rules.d/70-persistent-net.rulesSomething like:
# PCI device 0x8086:0xblah (rt61pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="58:94:6b:99:55:a0", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"If so, I suggest you remove the file and immediately reboot:
sudo rm /etc/udev/rules.d/70-persistent-net.rulesThen check again:
lsmod | grep -e rt61pci -e rt2xIf they are all gone now, how is the wireless working?

[zlyspl]

I did as you asked, deleted the file and rebooted the computer.

Not getting anything from :
lsmod | grep -e rt61pci -e rt2x

Typed in
cat /etc/udev/rules.d/70-persistent-net.rules again and I get


PCI device 0x10ec:0x8168 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="54:a0:50:0b:8b:6d", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

PCI device 0x14e4:0x4365 (wl)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="18:cf:5e:bf:0c:4d", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

Still encountering the same problems

[varunendra]

I was surprised to see rt61pci myself, since there is no hint in the usual places (covered in the script report) that are used to load a module forcibly. Does it load everytime automatically or did you load it manually? Maybe following some irrelevant guide just before generating that report?

I suggest you reboot, then without doing anything fancy, simply run -

lsmod | grep rt6
Does it (rt61pci) show up again? If not, please generate a fresh wireless_script report and post it here. If it does show up, take a look at syslog for hints on why is it loading -

grep rt6 /var/log/syslog

And as an attempt to get rid of it, try to blacklist it -

echo "blacklist rt61pci" | sudo tee -a /etc/modprobe.d/blacklist.conf
Reboot after this, and see if the wifi works now.

[zlyspl]

Checked by using
lsmod | grep rt6 nothing shows up

======== Done ========


Still having the same issues.

[varunendra]

Okay, so it seems to me that you probably loaded rt61pci manually last time.

Are you having the said problem with all routers/access-points or just the one you are currently using? Your current one, "ssbs-316", is using WPA/WPA2 mixed mode and many Linux drivers can have problems with this combination. Please log into your router/AP, and change it to pure WPA2-PSK with AES (CCMP). Also fix the channel to 1 or 11 if it is set to "auto". Save the changes and reboot the router. Now try to connect and browse/log-into the problematic sites. Is it any better now?

If not, please post back the output of -

dmesg | tail -40
..when it fails to login.

Is the browsing otherwise fine?

[zlyspl]

Yeah... you hit the bull's eye. Apparently it is the router at work screwing with me. Unfortunately, I don't have the authority to change my office's router settings. I could ask my IT although it would be very unlikely they be willing to change to WPA2-PSK with AES (CCMP).


Is there any other way of fixing this problem on my end instead of fixing it externally? Another question, I would have the same problems using SSBS-316 with a hardwire connection instead of wifi right? Since they are using MIX WPA/WPA2?

[varunendra]

Is there any other way of fixing this problem on my end instead of fixing it externally?
The proprietary driver you are using doesn't provide many options to alter or optimize the way it works. There are a few other things that we can try internally, but they don't deal with the encryption settings.

The things you can try are -

1) Set "IPv6" in Network Manager to "Ignore". It can sometimes improve the performance in slow connection problems.

2) Explicitly set the country code for regdomain settings, and hope the router starts liking the driver -

sudo sed -i 's/^REG.*=$/&US/' /etc/default/crda
sudo iw reg set US
If you are in a country other than US, replace 'US' with the appropriate country code. Basically, you have to match the country code with that in the router, and when we can't check that setting in the router, we assume it must be same as the country it was sold in. To find out the country code for your country, please refer to this table : http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Decoding_table

3) See if you have more than one version of the driver available -

apt-cache show bcmwl-kernel-source | grep Version
If you see more than one version, we may try the other one.

4) You may try different DNS servers that are faster/more efficient for your area. To change the DNS servers, you need to change the "Method" under "IPv4" in Network Manager from "Automatic (DHCP)" to "Automatic (DHCP) address only". Choosing this option will make the "DNS Servers" field editable, where you can define your preferred DNS servers. An example of what to put in the "DNS Servers" field is -

8.8.8.8, 8.8.4.4
..where 8.8.8.8 and 8.8.4.4 are Google's open DNS servers. Save and close the settings, then disconnect/reconnect for the change to take effect.


Another question, I would have the same problems using SSBS-316 with a hardwire connection instead of wifi right? Since they are using MIX WPA/WPA2?
No, the encryption settings are only meant for wireless communication. The wired connection is not affected by wireless encryption settings, so it should work right away. If you face the same problems with a wired connection too, then the problem is almost certainly the firewall settings of your office.

[zlyspl]

Got my IT to install a hardwire, it is even worse than the wifi unless I haven't installed the drivers for my Asus ethernet card correctly? If it is the firewall settings, what would the IT have to change?

[varunendra]

Let's first see your wired connection status. Please show us the outputs of -

sudo lshw -C network
ifconfig

Unless the problem is 'exactly same', or at least reasonably similar, we can't blame it on the firewall.

[zlyspl]

Found this on another solved link and I was wondering if this driver would work better? The person got a Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
The link to the post is http://ubuntuforums.org/showthread.php?t=2224920


sudo apt-get purge bcmwl-kernel-source
sudo apt-get update
sudo apt-get install linux-firmware-nonfree

[varunendra]

Whenever we have even the slightest hint that the native b43 driver *might* work, we try that first. As far as I know, your card is not yet supported by that. So the thread you found is useless, unless the b43 driver has been updated beyond my knowledge.

Everything looks pretty solid with Ethernet. What is the ping result? That is -

ping -c4 192.168.1.1
ping -c4 8.8.8.8

And you never answered this -

Is the browsing otherwise fine?
..means, if you browse a site that doesn't require login, just any random website, is the browsing fine then?

[zlyspl]

if you browse a site that doesn't require login, just any random website, is the browsing fine then?

Well, it is fine for most websites. I have problems with yahoo.com, popsci.com for some reason. Unfortunately I do not know the reason why. I can connect to those websites as well as websites that require username/password fine with my home wifi.

[varunendra]

Once more, you answered only half of my post. The ping replies might (or might not) have shed some more light on the issue. And..

Well, it is fine for most websites.... I can connect to those websites as well as websites that require username/password fine with my home wifi.
..once more, I am inclined to believe it is a firewall issue.

Could you ask your IT guys to temporarily connect your Ethernet connection directly to the router bypassing the firewall (assuming the firewall is separate than the router)? If they have added some custom firewall policies within the router, can they temporarily disable them on your request? This will just be a test of whether the issue is indeed the firewall or something else. After it is confirmed, they can put you back on the regular connection. If they agree to do that test, make sure they reboot the router (if the policies are defined within the router) while you reboot your laptop to allow a fresh attempt with the changed configuration.

If it actually turns out to be their firewall policies, it is upto them how they sort it out. I do have some experience with enterprise class firewall, but complex fw policies can go beyond my level of expertise about them.

I wasn't able to get my IT guy to bypass the firewall (security reasons). However I was able to tests other computers (windows) (Apple) also cellphones and none of them have any problems with username/passwords websites or the websites I mentioned above.

P.S. I apologize for sometimes answering half a post. I cannot reliably use Ubuntu forums at work because of the wifi reasons so I have to do so at home but by then I wasn't able to do any pings or other troubleshooting. I'll try to get them ASAP.

[varunendra]

Oh, sorry about that comment then, I though you (accidentally) just ignored the ping part.

Frankly, I'm almost out of ideas. Those I still have don't logically fit very well. I might have missed/skipped some obvious things to check/test/tweak, but then it is not uncommon for me to post in a hurry these days.

So let's just summarize the current status to save us the time of going through all the previous posts. Please either confirm or correct these, and obviously add anything that you consider to be a significant/important observation -


1) The problem is that you can not browse/log into those websites correctly that require you to login with a username/password (Plus "yahoo.com and popsci.com" which you named explicitly ?).

2) Browsing other websites, downloading etc. is fine.

3) The problem occurs ONLY in your OFFICE network, not in home (anywhere else?)

4) The problem is SAME (?) for both WIFI and ETHERNET (you only said "It is worse" for Ethernet in post #15. Please describe the behaviour of Ethernet (cable) connection if it is not SAME for both WIFI and EHTERNET).

And the only idea for now, could you test the network in a Live session? Means boot your laptop with a Live DVD/USB and check the network behaviour (both WIFI and ETHERNET, one after other, if possible). The WiFi should work without installing anything on a Live session, and so should the Ethernet. If you can do this test, please post the wireless_script report from that session for reference.

I''ll try this once this weekend is over and see if there is a difference. As for the rest, here's the rundown.

Yes, I get a ERR_CONNECTION_RESET or ERR_NOREPONSE_SERVER Page. As for "some" websites like Ubuntuforums, it sometimes logs in, it sometimes just get an extra long waiting for website message. Other times for Ubuntuforums, I can hit the stop load page on my browser and everything popups up immediately.

2) Browsing other websites, downloading etc. is fine.
Downloading is fine as long as it is not from sourcenet. Wikipedia, msn.com works perfectly.

3) The problem occurs ONLY in your OFFICE network, not in home (anywhere else?)
Correct. I'll see if I get a chance to test the wifi at my local Starbucks to if there is any problems.

4) The problem is SAME (?) for both WIFI and ETHERNET (you only said "It is worse" for Ethernet in post #15. Please describe the behaviour of Ethernet (cable) connection if it is not SAME for both WIFI and EHTERNET).
The ethernet cable is slower than the wifi, more websites does not load at all where as wifi loads non-troubled pages at a normal decent pace. Ubuntu forums does not work at all with ethernet while it works at times for wifi. Unfortunately the same problem occurs with the ethernet when compared to the wifi.

One thing I forgot to add or mention is that I had downloaded a VPN that is compatible for Ubuntu which installs Cisco IPSEC by typing

sudo apt-get install network-manager-vpnc -y

Not sure if this would anyway affect my ethernet or wifi.

In your next post, I would like to see the outputs of -

sudo lshw -C network
nm-tool
ifconfig
sudo ethtool eth0
..while you are using the Ethernet connection.

We have been (surprisingly) noticing a series of ethernet related problems recently, especially slow speeds and failure in connection. I wonder if the problem you experienced is a similar one, not anything that is causing the trouble with the WiFi. Possible just a bad coincidence of two independent problems (?).

zlyspl,

Did you post any reply to this ? -

Is the firewall interfering?
sudo status ufw

I think the question got lost in distractions. We are talking about firewalls, but did we check the internal one? Sorry if I missed your already posted answer, please post it (again, if you already did) to confirm.

The only thing I can think of now, besides external factors, is trying a lower MTU (Maximum Transmission Unit) value. In Network Manager, try MTU values 1492 or 1392 instead of 'Automatic'.

Sorry for the lack of updates on this problem. This problem have been resolved, the office where I work fixed the problem by using a different router now. So your initial prediction it was the router is 100% correct. I appreciate the help and hopefully this would help others.
