I have a Netgear WNR3500L wireless router. I assume it's v1 because on the back it doesn't have "v" anything. :-) Firmware version V220.127.116.11_35.0.53NA.
When I connect using g I get 22+Mbps download speed. When I connect using n I get 10 Mbps. I've tried using both WPA2 only (laptop reports 130 Mbps connection I believe) as well as the combo WPA+WPA2 (laptop reports connection of 117 Mbps). Broadband download results don't change - they stay at the 10 Mbps level.
I've fiddled with some of the settings on my laptop's wireless card - but the results are the same.
For now I'm just trying to figure out where I should focus my investigation and fiddling efforts - on the laptop or on the router.
