    First off, my specs:
    Adapter: Realek RTL8188EE 802.11bgn Wifi Adapter
    Router: Linksys/Cisco WRT400N (Known to have connection issues in the past, but I explain why this probably isn't a factor.)
    Not sure what else is needed...

    So, I'll boot up my laptop and everything will work fine. My download speeds will be somewhere near 20-25 mb/s and uploads are around 4-5 mb/s. I'll also ping test my computer with no packet loss, a ping around 20 and jitter around 1-3%. It all looks great and dandy (Pics below). Except, after about 15 to 20 minutes, my download speeds will dropoff to about 20-50 kb/s and my ping test goes through the roof to about 70-90 with jitter near 70%... Not good at all.

    Now, I have the suspicion this is being caused by my internal wifi adapter (the Realtek), because when I use another external usb adapter (TP Link TL-WN722N) my speeds never fluctuate and I have no problem, ever.

    Is there anyway to narrow down what this could possibly be caused by? Plus, I should mention, I've uninstalled and reinstalled the driver for my internal adapter so many times its not even fun anymore. After I install, the speed will jump to the 20-30 mb/s range, but again will drop after 20-30 minutes.

    I couldn't find the screen shot of my outrageous ping beside the horrible download speed but, I'll keep looking...

    EDIT: I'll use Xirrus Wifi Inspector to see relative signal strength, and according to it, it never changes..... Gah.
