Wireless Connection Not showing in Network Manager

[agirlnameddanni]

before i did updates, my connection was working fine.
and the wireless connection showed up in the network manager, but after i rebooted, after the updates, it was just gone.

i can't really post any results of commands because i can't get on here on my linux box.

any ideas???

check your drivers first, make sure the device is still working before you worry about network manager

if a kernel upgrade happened you might need to reload firmware, or rebuild a kernel module or something, not sure because you didnt tell us what distro you use and what wireless chipset you are using

What distro is this?

[agirlnameddanni]

distro?
like what im using?

sorry. i forgot that. Im using Ubuntu 6.06, Drapper Drake.

and my my wireless chipset? (sorry im very new at this...)
im using a D-link AirPlus XtremeG DWL-G520

Thanks for helping!

what modules are being loaded?
(find out with "lsmod")
what was updated?
what is the line from "lspci" that refers to the card?

[dkeav]

that device has several revisions, all with different chipsets, that is why we ask for chipsets because make and model tells us nothing

the lspci command can give you the chipset model and revision for your wireless chipset, please run the lspci command and post the relevant information for your wireless chipset

[psych-major]

OK, the upgrade most likely did something to the package linux-restricted-modules-generic.

Open Synaptic and search for this package, then choose 'Reinstall' After it finishes, it may ask for a reboot, after which your D-Link card should work.

Actually the "Airplus Xtreme G" tells me it's Atheros, which obviously needs the madwifi driver. My previous post should fix it...

[agirlnameddanni]

i dont seem to have that specific package..

similar ones that i do have include:
linux-restricted-modules-2.6.15-23-386
linux-restricted-modules-2.6.15-23-686
linux-restricted-modules-2.6.15-23-k7
linux-restricted-modules-386
linux-restricted-modules-686
linux-restricted-modules-common
linux-restricted-modules-k7


earlier, i tried a different card called "speedstream" which caused the wireless connection to come up in the network settings with a different interface name, "eth1". (the interface name was "ath0" before the updates, when i was using my dlink)
but id like to use my dlink if possible...


je_fro, i can't really cpy/pst the results of those commands due to the fact that i can't get the internet on my linux box.

ctually the "Airplus Xtreme G" tells me it's Atheros, which obviously needs the madwifi driver. My previous post should fix it...

going from memory, the difference between him having a atheros chipset and a TI-ACX chipset is a "+" in the model name, and a rev number

sorry if i dont trust users to be exact in their included information :)

[agirlnameddanni]

alright, i used the lspci command,
and found that the chipset is Atheros, and rev is 01, if you needed that...

[dkeav]

doing as psych-major said, reinstalling the linux-restricted-modules package and reloading the madwifi modules should get your ath0 back, then network manager will start working again

[agirlnameddanni]

i marked that package as reinstall, and clicked apply, and it didn't download because it came up with an message saying
"The Following Problems Were Found On Your System:

Temporary failure resolving 'archine.ubuntu.com'."

:(

[dkeav]

its going to need internet access to do this, so plug in an ethernet cable or something and finish your upgrades

[psych-major]

That other card you mentioned should work, you just need to be online, the atheros card doesn't need to be present for the fix to be applied.

So, use the card that works, update your packages and install any remaining updates, then mark linux-restricted-modules for reinstall. Normally it's generic, unless you have installed a different kernel such as x86_64 or i386. You can look this up by opening the gnome-terminal and entering uname -r
Whatever kernel is indicated by that command, find the restricted modules package that matches and either install or reinstall, then power down, put the D-Link card in and fire it up with your fingers crossed!

The D-link card uses an atheros chipset, by the way, which is why it comes up as ath0. The other card uses some other chipset, thus the eth1. (The ethernet port is eth0)

Hope this helps!

[dkeav]

if you are unsure which modules package to install

sudo apt-get install linux-restricted-modules-$(uname -r)

[agirlnameddanni]

yes! i got it working with the dlink! thanks guys!!

[dkeav]

congrats, enjoy
