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=Down...).

In all instances, I can get 5mbps upload however.

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.

Check that the WiFi channel your router uses is the least congested around.

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).

I'm talking about the WiFi signal channel, which is probably 1, 6, or 11.

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...
