Wi-fi USB Adapter Issue

Hey everyone. I seem to be having a issue with my Wi-fi USB Adapter on Windows 7. The one I purchased is linked below.

I just upgraded to Verizon fios, so I was expecting to see a significant increase in my download speed. However, my speed seems to cap at 11mbps, if it even reaches that high, while my internet plan supports up to 50mbps. I understand a wireless connection may not reach as high of a speed as advertised, but this is pretty low. I'm not too knowledgeable on these adapters, but it appears to be stuck in 802.11b and I haven't found a way to reach g or n speeds. Unless I didn't understand the product description properly, I thought this supported all three. I tried reinstalling the necessary setup files as well as updating to the latest driver from the manufacturer's website, but I haven't seen any new options appear.

Would anyone have advise on what I can do to improve my speed, or is this adapter really capped at 11mbps? Any help would be very appreciated.

Have you checked your wireless router, I bet it's the wireless setting on it that is not allowing you to connect o B G or N.  I used to do home PC repair for a side business and 9/10 times with verizon fios customers, the 4 port router/combo wireless was always setup wrong.  And I saw that the wireless signal was stuck at a default channel 6 and at B speeeds only.

So get your password to login to your wireless router and check that.
