Yes, it's a problem of the rtl8192cu driver. There is a new driver for
that chipset in the making, its name is rtl8xxxu and it can currently be
found here:


So far it only supports STA and monitor mode but it's pretty stable and
does not suffer from these outages.

I recently created a OpenWRT package for it which I will post to this
mailing-list soon, but it only works on OpenWRT trunk so far.
