Hello, I am adding some experience and a new dump. Trying to get more data, I build my own kernel from ubuntu sources, leaving JUST iwl3945, and enabling debugging. I still have the issue. However, I notice the ... crash? happens more often if I am far/low signal. While I am near the AP, the occurrence is quite low. I now read there is a suggestion to turn off power save, and I will do for further tests. In case it is relevant, here is my .config: https://pastebin.com/kJMrQSqr
