I am having very similar problems with the same router. SamKnows shown my exchange is 21CN enabled but I don't know if it is active yet. About once every couple of days I loose sync (Netgear log) and have to reboot router or just unplug it and reconnect then all OK.
I only get Loss of Sync - the router stats show it is still connected at a good speed. (>5500kbps)
If I complain to my ISP I will just get the usual mantra, "Have I tried connecting to master socket", "Have I disconnected all other devices" etc. - not too practical as the disconnections only occur once every few days.
I have just bought the new Netgear router DGN2000 to see if this fixes problem. I will report back when I have tried it.
