My internet speed has been pretty crappy lately, and I have no idea why. My roommate's speed is just fine. We're both using USB dongles, his computer is about 4 feet from the router and has great speed. Mine is about twelve feet away, with a wood and plasterboard wall in between. I have 5 bars on my wifi signal thingy. I'm using a 5 dollar dongle I got on newegg. It had good reviews so what the hell. I don't think its the donge because this only just started happening. I had good speed with it before. My brother is normally on my laptop directly between me and the router so could that be causing it? When downloading a game on Steam it fluctuates between like 200 kb/s to like 1.5 mb/s. This only recently started. What's causing it?
