Internet Snow 10.6.3

[maxk77]

hi, i installed snow leopard 10.6.3 using iAtkos S3v2. I have 2 problems.

1. Ethernet automatically sets an i.p which is completely different to my normal one.
ex. 169........... (auto ip) 196.168.0.. (normal ip)
How can i set it to use my normal ip?

2. Does anyone know how to get Atheros AR5007EG working? For Wifi?

Thanks in advance
Max
