Hello all! I have recently noticed that my wireless card, the stock Ralink RT3090 will not connect at a wireless speed faster than 20-25mps. I can connect with a network cable to my router and get 65+ mpbs.
My wireless router is the Netgear WNDR3400, so I know it supports the speed. I have double checked the drivers in the system and they are the latest available. I also went into device manaer, clicked on Ralink RT3090, properties, and tried to make sure that 802.11 a/b/n was selected, but there is no 'wireless' option under the properties for the card .Does anyone have any ideas? Its got me stumped and I'm usually pretty good at figuring these things out. I have attached a picture of the wireless properties as I see it on my screen. The driver version is 188.8.131.52 from 18FEB13. Any help would be greatly appreciated!

Yes, I have updated from Lenovo and Ralink as well. Even the Ralink WLAN software only has a maximum throughput of 54mbps, and I know the wireless card in this laptop will do better than that.

I worked through both suggested articles with no luck. I made sure I am the only computer connected to the router to make sure an older device wasnt causing the router to throttle the speeds. I uninstalled and reinstalled the drivers again to be sure. Checked all options, turned on the suggested functions from the first article, and checked in safe mode with the same result. I did watch the speed on a wlan monitor SLOW DOWN during a test on speedtest.net. Dropped from 54mbps down to 36mbps, but rose back up once the test was over. This is maddening because I even double checked the card to make sure it was an 802.11n card installed.
