Need some advice here from people who have experience with LANs and internet connections. Ok, so, here's the setup. I have a router connected to a modem which provides 2mb broadband. PC 1 is directly connected to this router via an ethernet cable, PC 2 and PC 3 are directly connected via Wireless. 1 and 2 are used to surf the web and occasionally download things, nothing big. PC 3, however, is used for gaming (including online). Normally the connection to the internet is enough to get games to run without a lag on PC 3. When PC 2 is connected and is used to surf the internet at the same time there are small hitches but nothing serious. However, when PC 1 is connected internet speed for PC 3 falls dramatically, even if PC 1 isn't sending/receiving a lot of traffic. This leads me to believe that the router gives some sort of priority to the ethernet-connected PC 1 over the Wi-Fi PCs. I did some research and the closest thing I found to a priority function is a thing called Quality of Service, which is enabled on my router. Will turning it off help? This could also be because the ethernet cable connects PC 1 to the router with a speed of 100mbps, while the wireless connects the two PCs with a maximum speed of 54mbps. If this is what's causing the problem, is there any way to limit the speed of the ethernet connection?
