View Full Version : [ubuntu] No more Wireless, not detecting any signal

I went to a hotel over the weekend and they only offered internet with a hardline. So I plugged in the Cat5, used the net over the weekend and left. When I came home my Pangolin was not detecting my wireless signal at the house. My roommate was online so I know the signal is there. I went to school and am still not able to detect any signals. I opened the Network Manager and no signal is shown. I then clicked Connect to Hidden Wireless Network The dropdown Connection tab had all of my wireless connections I have been using. I tried connecting and none of them would work.
I can't figure it out. After scanning through forums for 2 hours I ran some terminal commands that may help

Any other ideas? I could connect to wireless fine before I used the ethernet cord, but I have been unable to pick up a single signal since. :confused:

I have also tried restarting the computer, turning it off then on and going to the Network Manager and enabling networking and wireless through there.

That first comand is supposed to be lspci (lowercase of LSPCI, not Ispci).

It looks like you have a Realtek 8111/8168B ethernet controller (which has those r8169 driver modules loaded). It is worth searching this forum for "realtek 8168" to find some threads about what goes wrong with those cabled ethernet connections.

I'm still not seeing what kind of wireless interface you've got (and I didn't see ANY modules in the lsmod output for what I would consider the "common" ones either).

One thing about the default Network Manager- it tries to keep a connection and will try to switch back and forth between wired when available and wireless at other times (when everything is working "perfectly" :roll: ). Have you tried unplugging the ethernet cable before you restart ubuntu to "force" a wireless connection? Sometimes the [Gnome] Network Manager will get "stuck" or confused.

A lack of wireless modules definitely points to a problem though from what I'm seeing. Let's try to figure out what kind of WiFi hardware that is.

Can you post the results of these terminal commands (it looks like the lshw above got cut off a little):


lspci

lsusb

sudo lshw -C network

uname -a

Yea I noticed before how it will signals will jump from wireless once a hardline is put in. Yes previous to posting I had restarted the computer while the ethernet cable was not plugged in.

The commands I had posted above were from my computer while no ethernet was connected (ran command> copy paste to thumb drive). The commands I am going to paste right now are ran off of my computer while a ethernet is connected and I do have access to the web. Didn't know if that mattered at all.

I also noticed that under the "lswh -C network" I ran it says "*-network DISABLED", I'm not to computer savvy so I don't know if that is related or not.

Here are the commands you requested north:

OK- that's a 32-bit version of the 2.6.27-16-generic kernel (which is pretty old)- do you know if you are running Jaunty Jackalope 9.04 ubuntu or older? That might actually be a good thing- there have been a lot of problems with the newer Karmic 9.10 version (but it might support new hardware better).

Your wireless is a Intel Corporation PRO/Wireless 5300 AGN [Shiloh] with the logical name "wmaster0" and uses the driver iwlagn.

Can you post the results of this terminal command:

lsmod | grep iw

I have never worked with that particular wireless though. There have been a bunch of

recent threads here though- you might want to read the ones with the most posts/replies- they usually have the most information.

Here are some threads for that Intel 5300AGN "Shiloh" wireless:

I am not sure what version and my mind is fried from studying finance lectures all day haha. I know my update manager says somethin like "new software distribution available 'Ubuntu 9.04'" or something along those lines, so I am guessing it's older. I will look threw those links and post my progress tomorrow. Thanks again North

I'm back in ubuntu now (Gollum sez: Na$$ty Windoze Vi$$tases ;) ) so I can finally check my notes from a Linux file system.

Try this command for your ubuntu version:


cat /etc/lsb-release

That last lsmod command is modified specifically for those Intel 5300AGN driver modules (that look OK to me, but I honestly don't have a clue what those specific ones are supposed to look like). It is common for one module to depend upon several others and that is what it looks like.

You might want to post on one of those other "Intel 5300" threads and link to the results above- someone who is running that same hardware should know more about those Intel beasts than I do. I've never even seen one before.
