When I plug my laptop directly into the router (Motorola SBG6580 (I can only get Time Warner here fml)) I speedtest to 30mbps. When I use my wireless usb (TP-LINK TL-WN722N) in the same laptop and sit it right next to the router, I max at 10mbps.

My other MAIN problem is when I plug in the same wireless usb into my desktop, which is in another room around 40 feet from the router, I have this problem where I burst up to around 5mbps and then it lowers to around 2. I placed the laptop usb where the desktop usb is and could still get around 8mbps, so something is wrong with the desktop. Sometimes if I unplug the router several times I can get higher, but this is the typical speed. I also have the extension for this usb but placing it in different places doesnt seem to help.

I didnt see any wireless drivers for my mobo, only a lan driver which I have installed (http://www.asrock.com/mb/Intel/Z87%20Extreme6/?cat=Download&os=Win764).

In all instances, I can get 5mbps upload however.
 
Solution
Find a PCI/PCIexpress card for your desktop with suitable antnaes, and check whether you can find miniPCI card (or whatever is compatible) for your laptop. USB is inheretly slow network interface.

I did just start looking into this, although still not sure why it jumps from 2 to 10 randomly.



I actually tried changing the 802.11 Band from 2.4 to 5.0 earlier but then I couldnt find the signal again, so I set it back to 2.4. I did set the bandwidth to 40 though (it was 20).

Oooh ok, it's currently 6, it lists 1-7 so I can try those. I'll get back to you tomorrow, hopefully it helps...
