[Madwifi-users] TP-WN510G stopped working

[Mark A. <al...@wu...>]

Using madwifi I was able to use my TP-WN510G for one day. Then it 
stopped working. It appears to still see the access point, but
it cannot connect to it:

> ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
>From 192.168.1.50 icmp_seq=2 Destination Host Unreachable


Annoyingly, it works fine under Windows XP.


Here is ifconfig output, with some addresses disguised with XX:
