When the link goes down, a simple "ifconfig ath0 down" followed by 
"ifconfig ath0 up" does not work. The link is restored at the 802.11 
level, but no ping would work. If, instead of "ifconfig ath0 up", I do: 
"ifconfig ath0 up nwkey 0xblahblah", it works fine again. I *really* 
suspect WEP to go astray.

There was the same problem long ago — I mean during spring, when I 
bought my card. Then the hal code and driver were updated and I noticed 
considerable improvement (no noticeable disconnections anymore). 
Something must have changed during this summer, while I was away on 
holidays. This is some sort of regression.
