I've tried ad-hoc mode right now with "slightly better" results. Look
at the following:

How can it be that the response times vary between 1.5ms and 2500ms
within seconds? This is going all day long and I have to restart the
WG511 every few minutes.

In managed mode the connection to the AP breaks down completely, in
ad-hoc it seems to be able to keep it up, although with much worse
response times.

I have already tried different WLAN channels with no success.

The OvisLink WL5400 PCI card on the other end doesn't care, I've never
had to restart it so far.

Any ideas what could be causing this unstable connection?
