It's me again. I found more strange things about my problem. I think |
| 2 |
I'm getting closer: |
| 3 |
|
| 4 |
arp -n in the Gentoo Station reports: |
| 5 |
169.254.0.1 (incomplete) ath0 |
| 6 |
|
| 7 |
Where 169.254.0.1 is the address of the AP. |
| 8 |
tcpdump -vv -i ath0 arp: |
| 9 |
|
| 10 |
20:50:21.984182 arp who-has 169.254.0.1 tell 169.254.0.3 |
| 11 |
|
| 12 |
|
| 13 |
While I'm pinging the AP, I got "truncated-arp" messages in the AP |
| 14 |
"tcpdump -vv ath0 arp" output. |
| 15 |
|
| 16 |
The Station machine just got two replies: |
| 17 |
64 bytes from 169.254.0.1: icmp_seq=424 ttl=64 time=0.400 ms |
| 18 |
64 bytes from 169.254.0.1: icmp_seq=426 ttl=64 time=2998 ms |
| 19 |
|
| 20 |
|
| 21 |
It seems like my problem has something to do with the "Signal Too |
| 22 |
Strong" http://madwifi.org/wiki/FAQ/SignalTooStrong issue. I will move |
| 23 |
the AP to a place far from the station. |
| 24 |
|
| 25 |
So far no one replied to this, but I will keep posting in the hope |
| 26 |
that my attempts to make this works helps someone in the future. |
