[ubuntu] Ubuntu on a mac a1181, wifi look connected but no internet or IP

Hi guys, I recently tried to bring an old mac a1181 back to life with linux, everything looks good, but I discovered that the wifi although it said to be connected had no internet.


The wifi board model is BCM4321, I tried several drivers and several methods that I saw on the internet but none of them solved my problem.

Can you guys help me fix my problem?


Thanks.
