Sounds more or less normal. Wireless is in no way a substitute for wired when it comes to speed, especially if there are others on the same wireless network.
If you're in the US, my advice would be to go to the Monoprice website and just buy yourself a 50ft ethernet cable, maybe even 75ft so you have some slack to go behind furniture and generally keep the cable out of the way where people may trip on it.
Hey guys, I have just recently built my first PC and I'm having some issues with the internet on it. I don't have an ethernet cable long enough or wired to reach my room from the modem (about 40 feet away) so I purchased a micro USB transmitter to connect wirelessly. I noticed immediately that the download rates were slowed down dramatically compared to my laptop which was loading webpages lightning fast on the same network. I have since troubleshot the transmitter by using it on my laptop and disabling the internal antenna and it works perfectly fine on the laptop so this leads me to believe it's something with the desktop that is causing an issue. I'm running
ASRock H77 Pro4-M Motherboard
Intel Core i5-3570K Processor
MSI GeForce GTX 660Ti GPU
If there's any additional information needed to diagnose this problem I'll be sure to provide it as needed.
