I have had the 3500L for over a year now and I love it. In November I bought a new laptop and it connected to my router no problem at 150Mbps and ran like that for some time. Just recently I noticed that it was only connecting at 72Mbps, so I thought I'd buy a better quality usb adapter thinking there was a problem with the one in the laptop, but its only connecting at less then half of what it should. I checked in the router settings and its set to connect at 300Mbps. so my questions is, is there anything else I should check or do? any ideas or suggestions would be very helpful.
