mobilenvidia Posted August 9, 2007 Report Share Posted August 9, 2007 Dudes, now it's my turn to have a problem. My Wife's Dell D820 has an Intel 3945ABG WLAN card. Everything works fine with G band connections. But I have just gotten a new dual Band Router, it can output both A and G simultaniously. My Inspiron i9400's Dell 1500 WLAN card sees both A and G bands but the 3945 only sees G Why would the 3945 not see the A band router ? It works just fine in G, but I would prefer both lappies on A Got me stumped. Link to comment Share on other sites More sharing options...
Bill Posted August 9, 2007 Report Share Posted August 9, 2007 If you turn off the G output does it see the A? You might have to manually turn support for 802.11a on yourself. Link to comment Share on other sites More sharing options...
mobilenvidia Posted August 9, 2007 Author Report Share Posted August 9, 2007 Already tried that :) If I turn G off then the 3945 sees nothing There in no setting for just A, only A/G, A/B/G or B/G. Wonder if draftn has anything to do with it, as it's a draftn dual band router and the Dell 1500 hooks up at 270Mbps Link to comment Share on other sites More sharing options...
mobilenvidia Posted August 9, 2007 Author Report Share Posted August 9, 2007 I see now, the Buffalo dual band router uses 5180 - 5320Ghz Range, channels 36 - 64 The Intel 3945 uses 5745 - 5805Ghz Range, channels 149 - 161 Now it looks like I'll have to mod the Intel INF to fool it into thinking I'm in the US to hopefully get the missing channels. Learning curve is steep. Good channel reference is here Link to comment Share on other sites More sharing options...
mobilenvidia Posted August 9, 2007 Author Report Share Posted August 9, 2007 Ha, found the culprit. The Dell D820 comes with an Intel 3945ABG WLAN REV00 card My i9400 came with a Intel 3945ABG REV02 card, but now has Dell 1500 WLAN Once I swapped the 3945's over, the D820 has the REV02 card and instant A band recognition. Now both lappies use A Band happily, Dell 1500 @ 270Mbps the 3945v2 @ 54Mbps Printer happily uses G Band as does my neighbours Network and now I'm away from cordless phones for clean airwaves. Looks like the Rev00 card is crap and only works with limited channels (upper A band) Link to comment Share on other sites More sharing options...
