I also get an error along those lines with my N9, and I'm on PR1.3, didn't report this as it didn't really bother me much as fixing it is a simple Modem reboot, but that sucks if other devices are connected, eg someone playing online on PS3, you have to wait till they done. It happens to me EG when I leave the house and the phone switches to 3G, go to the shops come back, WIFI no longer connects, modem has to be rebooted. I use a Netgear Router DG834GU, funny part is I visited my friend over the weekend, had Pool Party Outside, from the Pool I couldn't get signal to his router, but everytime I went back in the house it connected flawlessly, and he uses a cheaper modem than mine! This has to do with my Wireless Settings on Router I suppose, but my wife doesn't have this problem!
