Windows 7: Desktop WIFI Internet Issue - Connected, but Slow/Dropped Internet

Desktop WIFI Internet Issue - Connected, but Slow/Dropped Internet

I've been battling this particular issue for a couple of weeks now without much success. I have a custom built desktop where my WIFI connection will deteriorate to the point where internet (and gaming over Steam, etc...) will be either painfully slow or unable to load pages at all. Windows claims throughout that I am connected to my WIFI network with internet access and good signal, even when I cannot reach any internet pages.

This problem has happened at 2 different locations (on different WIFI networks), and with 3 different WIFI adapters (TP-LINK TL-WDN4800 PCI, TRENDnet TEW-684UB USB, Edimax EW-7811Un). At both locations, I have another laptop and a phone that can connect to the WIFI network just fine. I even got a couple of the adapters to work fine on the laptop without the issue.

I've found that disabling NetBIOS seems to temporarily improve matters (I'd read elsewhere that that can cause issues), but it has not resolved the problem. Also: I'm getting DNS errors in the Windows 7 event logs:

"Name resolution for the name XXXX timed out after none of the configured DNS servers responded."

ipconfig results are posted below. Images of Xirrus (1) and its connection test (3) are attached. Any help is very much appreciated!
