Sony VGN 320e issues

Hello Folks,

I recently bought a Sony VGN 320e laptop. I have been a Ubuntu user before this and i installed OpenSuse 11 first time.
The hardware spec sheet is here -
VGN-N320E/B | REFURBISHED - VAIO<sup>®</sup> Notebook N Series VGN-N320E/B | Sony | SonyStyle USA

Basically I have 2 problems which i can not fix -

(1) My wireless is not detected. I have Wireless LAN : Atheros IEEE Network Connection (802.11b/g).

(2) The in built Mouse Pad on Laptop doesn’t work properly. The cursor movement si very slow and taps are not recognized.

Could anybody please help me to fix above issues?

Thanks
Amit
