View Full Version : [ubuntu] Problem with Wireless connection

Hello,

I'm new to Ubuntu, and altough I'm confident with 9.10, I've got problems getting connected to the internet via wireless.

The problem is, that he connects to the internet after booting, but just for a few minutes. The connection seems to be solid and it shows, that I'm connected, but I can't open any pages.

So, I'm connected, but in fact I'm not. Using the wire does'nt lead to any problems.


Here are some information, which might help you:

the result of your iwconfig is showing that the access point isn't associated

unlike my results....

Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

to be sure there isn't another issue check the output of the following command

iwlist scan

it should give all the local access points / network names (ESSID), which in my case is "Mousquetaires"

You should be then able to connect using your 'network manager', which should be in either your <networking> submenu (or your <system tools>)

There are 2 possible options for networking tools, either wicd (which I recently started using in 9.10 as it was better) or the 'Network Manager' which I couldn't get to work.

to get wicd use the following...


sudo apt-get install wicd


then you will have a nice gui for selecting your wireless network, and setting the password etc.

Hey,

first of all, thank you for your help.

I've installed Wicd and it seemed like it worked fine for me, till he lost connection now. He can't find any wireless connection now, so I'm forced to use the wire again.


Anyway, here are my iwlist scan results:



lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

wmaster0 Interface doesn't support scanning.

wlan0 Failed to read scan data : Network is down



and my iwconfig, where my access-point isn't associated:



lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11bg ESSID:"EasyBox-EB4816"

How can I associate my access point, anyway?

Cafucho

Does noone have any idea? :(

EDIT: I now have another problem: I'm connected to the internet, using the wicd network manager, but after a while he suddenly disconnects because he cannot find any wireless network. So, I do have a connection for a while, but then he disconnects and says, that there is no wireless network.

I really need some help, because this really annoys me.

theDaveTheRave
March 31st, 2010, 07:32 PM
Cafucho,

the result of your iwlist scan shows that the wireless network is down, hence there is no chance of wicd being able to locate any wireless networks.

assuming, to get the wireless interface working you will probably need to perform one of 2 actions.

first, you may simply need to 'flick the wifi switch' on the front of the laptop to get it to start receiving.

You may then need to bring up the interface


sudo ifconfig wlan0 up

or possibly alternatively


sudo ifconfig wmaster0 up


If that doesn't work, you will need to determine what your wifi card is using the next snippit.


lshw -C network


using my output as a sample for what your response may look like



davem@Dartagnan:~$ lshw -C network

so I've color coded the stuff.

in green is the ethernet interface
in purple is the wifi interface, with the information regarding the wifi chipset highlighted in red

Using the product code of the device (highlighted in red) search the internet for details of how to get the card working.

Also post the info here here as then when you get it working you can post your solution and become a 'wifi guru' for your device, and help others with your potential solution.

Also post details of the laptop you are using, there may be specific quirks with the device on that particular laptop that means that the devic doesn't work by default, and it may be a really simple job to get the network device to initiate on boot.

Good luck, and sorry for the slow reply.

Hey theDaveTheRave,

many thanks for your help, of course it doesn't matter, if I have to wait for answers. ;)

As I mentioned, the wireless network is working after rebooting and after a while it losts connection.

So I rebooted and here are my results for iwlist scan:

Ok all, first off

thedandalion, the uses of the iwlist scan should scan a wirless device even if located on a desktop. You have the added advantage however of knowing exactly what you are using as I guess you can either look at the documentation that came with the adapter, or open up the box and have a look!

Cafucho,

so it seems that your wireless device is picking up the network ESSID when you boot up. Can confirm that this is the detail from your 'easy box' (normally you can access the web admin page by navigating to 192.168.0.1 or 192.168.0.255 in your web browser ~ again check the documentation that came with your unit).

One thing that does seem odd is that your device doesn't issue a product id??

So it occurs to me that maybe your main device may also work as the wifi device.

so a quick search on google gave me the following thread on the ubuntu forums...

http://ubuntuforums.org/showthread.php?t=843398

which may be of assistance...

also are what is your laptop?? does it happen to be an msi wind??

Again reading your first post saying you are using the r8169 module may mean the the above thread will be a solution for you.

When I did the iwlist scan it didnt pick up on my broadband wireless device and the lshw -C network didnt pick it up either. When I first plugged it in it prompted me to set up the wireless connection and identified the wireless device as well (starcom um100)

@David:


Many thanks for the link you searched out.

Concerning the thread I've got a question, which may sound very stupid, but I want to avoid any mistakes, so I would rather ask than getting more troubles. ;)

(Anyway, I'm sorry for my English.)


So, my question is, if I should use the following instruction http://ubuntuforums.org/showpost.php?p=5382164&postcount=10 or http://ubuntuforums.org/showpost.php?p=5393124&postcount=11 or should I even update my BIOS like mentioned here: http://ubuntuforums.org/showpost.php?p=5526807&postcount=15.

Without wanting to annoy you, I'm looking forward to hearing from you. :D

So, my question is, if I should use the following instruction http://ubuntuforums.org/showpost.php...4&postcount=10 or http://ubuntuforums.org/showpost.php...4&postcount=11 These solutions are for wired ethernet, not wireless. I am sure they will have no effect on your issue.

theDaveTheRave
April 1st, 2010, 03:51 PM
@chili555,

I must admit I was of the impression that the card controled both the wired and wireless functions, hence why I pointed the OP to the threads.

but however, I am willing to accept that I may have not understood the card details correctly, it just seemed odd that the OP didn't have a 'device name' for his wifi card?

again, the question for the OP is what is your laptop spec?? we can then search google / manufacturer site for info on the wifi card.

@Cafucho

as chili555 says, however I would sugest you put a question on the specific threads, as I don't know the issues surrounding changing the BIOS etc.

Sorry.

@thedandalion,

don't understand why your wifi card isn't showing up when you perform an < lshw -C network > ? are you performing it as root or a normal user? other alternatives could be to check the whole of the lshw info, try these.



sudo lshw -C network


or just



sudo lshw


they may throw out more info than you previously had. Also is there an 'on' switch on the device?? I know that on most laptop's there is a little button to turn the wifi on/off, but I don't have any experience of desktop internal wifi cards

There may also be a difference if you are using a USB wifi key (as opposed to an internal card), if it is the usb type try the following for getting information on the chipset



lsusb


perform this before and after attaching the device

the line that appears after adding the key is the info you need to search on google to get the wifi going. (sorry is that too obvious :popcorn: ).

ID 0bda:8198 Realtek Semiconductor Corp.His card, a USB device actually, is described here. They are never, that I have heard of, are controlled by the ethernet card's driver. It has it's own driver, rtl8187, that is loaded:
rtl8187 50624 0
mac80211 181140 1 rtl8187
led_class 4096 1 rtl8187

There is an updated rtl8187 driver in linux-backports-modules-karmic-generic, so I'd suggest as a start to install that and reboot. Let's see if the symptoms improve.

If the card is a USB device why did the detail still not show up in the < lshw -C network > ??

and only in the lsusb listing that the OP posted at the begining, and I managed to miss thinking it was simply related to something else!?

Sorry for that. it means that this has taken a lot longer to solve than it should have.

This may be a strange question, but are you sure the problem is internal to your laptop? The listing you gave in posting #7 shows:

Quality=63/70 Signal Level=-47dBm

My own wifi link is showing:

Quality=68/100 Signal Level=-67dBm

and that is not showing full strength on the signal meter I have showing at the top of my screen.

If you have low signal strength, other things could cause a disconnect, such as someone moving around the room, or interference from other sources - even other wifi sources.

You might also be using a wifi channel that a neighbour's wifi, because of "line-of-sight" and same channel usage could be overcoming the signal of your own wifi. In that case, try changing the channel on which your router is set.

Lastly I once had a router (a Belkin wifi router) which occassionally seized up, giving similar symptoms and needed rebooting - when I changed my router (to a Netgear router) all the problems I had went away. At the same time, the signal strength improved a lot.

Some cards report as 70 in the denominator (including one of mine). 63/70 is 90%. I would think that should be sufficient.

I installed them all now, but nothing changed. He continues to disconnect after a while, because he can't find any wireless networks.

I really don't know what to do. :mad:

Maybe I should wait for Ubuntu 10.04 and see if I get the same problem again. If so, there's no other option than installing Windows. :sad:

Cell 01 is my network, the others are my neighbours networks. :)

Something Irv2 says in his post earlier reminds me of a problem I had in one of my first wifi USB keys.

If I had the router set to use an encryption key for connection I would find that my link would occasionally drop out for what seemed like no apparent reason. My solution was to use MAC filtering on the box to this specific key.

Again I am going to ask what the laptop is that you are using, and to confirm that you are using a USB wifi key, there may be some oddity between your particular architechture and this key that may hold the solution to your problems.

Also test to see if you continue to have connection issues when you are say next to the router, this will eliminate any potential weak signal problems. I should add that this did solve my problem described above, but isn't exactly a 'mobile' solution!

I am also going to add that in my experience the signal strength of a wifi card is much improved on the linux partition compared to a windows one - so you may not find that windows is any better ?

Hey Dave,

again thanks for your help and sorry for my late response.

I've got a Toshiba Satellite L350, like this one here: http://edwardh.se/2010/02/06/toshiba-satellite-l350/

In his review, the author also underlines that the WLAN is a USB-Device. I don't know what a MAC filtering is, but maybe it's the solution for my problem?

I found something new: http://www.alstevens.co.uk/how-to-install-wireless-usb-drivers-for-ubuntu/

There he's installing a wireless usb-driver via ndiswrapper and the windows driver.

Cafucho,

the guy in that web page probably has it right.

if you try it out and have any problems drop a note back on to this thread and we'll help out where we can.

ndiswrapper should work on this, as various other users seem to be able to get it working.

try searching for your your card name on google for more potential instal solutions.

good luck

David
