Hi,
I recently got a Toshiba Satellite A215-S5837 laptop, and I just installed Ubuntu 8.04 Hardy Heron on it (dual-boot with Vista). Apparently, my wireless card is an Atheros AR5007EG (according to Vista's dev mgr.), and I heard the restricted drivers don't work, so I followed ToM-X's instructions in the 7th post in this thread:

I installed Madwifi and the interface shows up:


tpv@tpv-laptop:~$ sudo lshw -C network

I also ran iwconfig:



tpv@tpv-laptop:~$ sudo iwconfig

eth0 no wireless extensions.

wifi0 no wireless extensions.

tpv@tpv-laptop:~$

I am confused, though, because there are two interfaces: ath0 and wifi0.

Also, I tried to connect through GNOME's network manager, but my wireless network didn't appear at all. I tried to enter it in manually, but it wouldn't connect. Any help would be great.

(By the way, I only disabled the HAL driver in the hardware driver manager, not the support driver. Maybe that has something to do with it... but I don't know.)

D'oh. I forgot I had turned off the wireless adapter in Windows. It works now :)
