The problem is that with time (a few hours) signals are going down: from -80 to -93... Pings are growing, connect speeds are decreasing..

An interface disable-enable solves the problem but I don't think that this is normal. Has anyone an expirience like that?

What Wireless card is it? SR2?

It's a CM9...

any idea?

Well, it's a CM9...
Veru sensitive to noise, disable/enable or changing frequency is only help. It's 2.4 dude, so unless you're only one in area, get use to it

Good luck...
