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?
