I have the DGL-4300 and the wireless connection worked okay on OS 2006, with encryption, but occasionally I'd have connection issues or random reboots on downloads. Disabling encryption seemed to fix it for me. I have yet to try encryption on the OS2007 on 770 edition, because now that I have a Nintendo WII and Nintendo DS, it's easier just to leave the wifi open with a mac address filter. This is on D-Link firmware 1.8. (I'm just reading that they fixed a WPA2 issue with the Nintendo WII in firmware 1.8 so I may try to enable it again) Anyways, the connection drops are due to a bug and are detailed in the bugzilla.
