Ok, I've investigated this further. The strange thing is: whenever the
connections to the outside drop, I can ping and connect to any host in my
LAN (, but I _cannot_ ping from the WLAN client,
which is the inside interface of the ADSL router and thus the default
route. I can't explain why. "ifconfig ath0 down && ifconfig ath0 up"
solves this lock-up. Could this be a driver bug?
