I used prs-950 with my router (dlink dir-300 nru) with no problems, but one day I installed dd-wrt firmware... all my devices (3 noutebooks - me, my wife and my sister) worked just great, but sony... disconnecting every 60-65 seconds of inactivity. Tried every setting in dd-wrt - nothing helped. Installed original dlink firmware back and... it works!!! Now I'm happy user of prs-950 again
