Update on: How to wifi with ipw3945 on Dell Vostro ???
I still cannot wifi with my laptop but I can see that the laptop is
sending it's DHCP requests to the network, I can see the request being
answered by the server but somehow/somewhere the the response gets lost.
If I try to make a connection through the NetworkManager I see (using
tcpdump) the following traffic.
Questions about what I see:
- What are those "oiu Unknown" things I see?
-Are the lines with ethertype Unknown (which all seem to be from foreign
(== not mine) MAC addresses) from other AP's in the building?
- If so, could they interfere somehow with my dhcp requests?
- Why do I see IP6 things while my whole network is IP4?
