Cannot connect to internet with Atheros AR5005AG

[liberalist]

Hi everyone,

Kubuntu 9.04 looks fantastic and seems really a big step forwards from 8.10. However, I have a major problem: I can't connect to the internet. I have a wireless connection, which always connected effortlessly to the 64-bit WEP encrypted network. Now, with the new flashy network plasmoid, it does not work. It seems to be an issue more users have experienced, judging from this bug (https://bugs.launchpad.net/ubuntu-re...es/+bug/339313). It seems to be caused by kwalletd not being loaded. I tried to run kwalletd with the alt F2 dialog (both with and without sudo), but to no avail.

My card is an Atheros AR5005AG and I used a restricted driver before, but now it says it's no longer needed. I tried both with the open source driver and with the (alternate) restricted driver (madwifi), but both options did not work.

How can I solve this from a Live CD environment, or is it better to install anyway? Note that I do not have a wired connection nearby to download packages, which will complicate matters if I want to install network-manager-gnome or knetworkmanager (which is no longer supported I heard).

PS: I use Kubuntu since 7.04 and I remember that there was a way to connect using the command line, but I forgot... I am very bad with the command line.

Re: Cannot connect to internet with Atheros AR5005AG

you could try to install the windows driver for the card with ndiswrapper if the kernel dosent have the driver and you have acsess to the windows one (like on the cd that came with the card or dug out of the windows sys or sys32 files)

in a shell,or konsole

ndiswrapper will give the comands help.
ifconfig will show the devices that are UP
ifconfig -a will show all
iwconfig will show wireless devises that are avalable

man iwconfig will give you the man page to set it up command line stile!

once I did the ndiswrapper deal the default network manager did fine BUT I think encription has ben problamatic for pepole. ---- my card is linksys using the Atheros chip set---

but adding the encription via iwconfig may work---------let us know!

Re: connecting from the command line: It depends on how you're set up, I think, but here's what has generally worked for me:

Look in your /etc/network/interfaces file and see the interfaces (the line starts with "iface".) Figure out which one is your wireless. For me it's "ath0", which I'll use in the example.

At the command line:

sudo ifup ath0

Good luck...

Re: Cannot connect to internet with Atheros AR5005AG

I think that with the new kernel the network is probably wlan0 instead of ath0, but if wlan0 does not work try ath0. You /etc/network/interfaces file should look something like this
auto lo
iface lo inet loopback
auto wlan0 inet dhcp
wireless-essid yourssid
wireless-key your_key

Put your ssid and key in here. You can then try to reboot, and if you are lucky network-manager might not screw you up. Otherwise you can do the sure thing and run
sudo aptitude purge network-manager
After that you should be able to run
sudo ifup wlan0
and have networking.

Should you have to have your key sitting in a plain text file for it to work?

Yes.

Re: Cannot connect to internet with Atheros AR5005AG

vinny@Kubuntu:~$ cat /etc/network/interfaces
auto lo
iface lo inet loopback


and my wierless works fine.?

That file does not configure your wireless. It is happening somewhere else.

I am now posting this from my fresh Kubuntu 9.04 installation. It works! I did add open after the key, somehow this was necessary to connect. Strangely, it did not break the networking plasmoid (which now works as it is supposed to). And all without needing restricted drivers

Thank you for all your kind help. This release rocks, all my praise goes to the Kubuntu contributors.

Interesting. I suspected that a driver had now been included in the kernel, and this report seems to confirm that. Life gets much easier when you can use the standard procedures.
