I can't tell if said router/wap/wifi is setup with 802.11G compatibility or much else.
In short, try other settings.
I just got a Panasonic DVD Bluray (DMP-BD85P-k w/USB wireless pickup) expressly for streaming movies(Netflix, etc)It fails to locate my access pt(AP) when scanning but does find 3-4 others in the neighborhood. Provider (Qwest) couldn't help by .changing frequency of AP. I know signal is strong cuz I'm using my laptop right next to the DVD. Access Pt is Actiontec GT701-WG. Any suggestions?
