Is it any good to turn compression on on the interface which is in ap-bridge mode??
I am not sure if it is good, probably yes if you have clients which support compression too. So, as documentation says, this mode will advertise to the clients that it supports compression and if clients also support it, they should use compression and other clients should work just normally without compression. I haven’t tried this in real life, but I had problems with one point to point link and I just turned this off. I think I used CM9 cards for this link, but I am not sure. This is really hardware dependant stuff.
thanks 
’ spider ’ just told me tha it is no good tu turn it on on apbridge interface because almost everything is compressed allready by software on PC so…
