Not completely. There *is* a problem with the ath driver when used with
WEP encryption. I'm getting also those disconnections, and my card and
access point are in the same room, not 2 meters away one from the other.
I suspect there is something bulky in the code, because I seem to get
much more disconnections when I slow down the processor to half its
nominal speed (using an acpi trick). As if the WEP processing was done
in software. This hypothesis explains also why I get more problems with
128-keys WEP rather than 64-keys. But I can't be more precise without
any debug trace.
Sometimes, the network is up, but I can't get any TCP traffic. A tcpdump
shows garbage coming from the access point, so I guess these
disconnections really are connected to WEP. After a number of errors,
the link goes down.
