Hello,
I have just installed Ubuntu 7.10 on my desktop which has an Atheros ethernet controller. But I am not being able to configure my wireless. I use the network manager to configure it. Most of the times it shows connected as the blue icon appears in the panel. However, I can't connect to any webpage. In addition, when I right click on the wireless icon to view the Connection Information, it shows all zeroes.
I had been going thorough the following thread by "tredegar": linuxquestions.org/questions/linux-laptop-and-handheld-25/wireless-not-working-ubuntu-gutsy-7.10-597188/
but still couldn't setup my wireless.
Will give the output of the following commands FYI:
sudo iwlist scanning
cat /etc/network/interfaces
ifconfig
output for "sudo iwlist scanning":
----------------------------------------------------
lo Interface doesn't support scanning.
wifi0 Interface doesn't support scanning.

In addition, as mentioned at the end of the aforementioned post, when I give commands like sudo ifdown and sudo ifup, it gives the following output:
sudo ifdown ath0:
----------------
ifdown: interface ath0 not configured
sudo ifup ath0:
----------------
Ignoring unknown interface ath0=ath0
But I believe I have configured ath0 using ndiswrapper(I followed the info in this link: beginlinux.com/index.php/desktop_training/ubuntu/ubnet_m/ub_wirless, because when I enter the /usr/ndiswrapper-1.51/utils directory and give
the command: sudo ./ndiswrapper -l
I get output:
net5211: driver installed
device (168c:001A) present (alternate driver ath_pci)
---------------------------------------------------------------
I get the same number when I do lspci and lspci -n:
lspci output => 02.0c.0 Ethernet Controller: Atheros Communications Inc. AR2413 802.11 bg NIC (Rev 01)
lspci -n output => 02.0c.0 0200: 168c:001A (rev 01)
---------------------------------------------------------------
I don't have a clue what else to do so that my wireless is up and running

Any help would be greatly appreciated.
Wish you all a happy and prosperous new year :
