It depends on how strong your wireless signal is, how far you are from your router, and how strong the receiver on your dongle is. USB 2.0 has a 60MBps speed so you could theoretically get that speed. Can you receive the WiFi signal with your mobile device? You can extend the range of your WiFi signal using repeaters (for wireless solutions) or by adding a router (which will require an ethernet cable). Alternatively you can use an ethernet wall plug adapter (something like this http://www.amazon.com/Ethernet-Powerline-Wall-Plug-Adapter-PLA4111/dp/B00D7GF4XC). Or you can buy a PCIe slot wireless card which will give you greater speeds and should also have a stronger receiver.
