I was about to buy a 3rd different USB wireless adapter and even considering a PCIe model with external antenna since I kept getting horrible performance with the nano adapters. I liked that they could just be plugged into the back of the system to add wireless support and they worked great on the Raspberry Pi, but on a desktop the performance was not much better than a dial-up connection.  Before ordering anther product someone mentioned interference and I then did a bit more digging and found Intel actually published a whitepaper on this subject (Linked at bottom).

After testing I was able to clearly see the effects of 2.4Ghz interference and would recommend to anyone having performance problems with wireless adapters to get a USB extension cable.  Using the same Plugable nano-N wireless adapter I ran a speed test from 3 locations:

Connected directly to back USB port

Connected directly to front USB Port

Connected to USB port via extension cable 3′ away
