Hey, I currently have 50 Mbps internet through cox. Recently my roommate has started watching anime tv shows on a streaming site, it will only be him and I using the wifi internet and it will be super laggy while playing video games for me. I was wondering if this is normal... I would think I shouldn't have any problems with lag having 50 Mbps internet, with it being only two people using the wifi also... Is there any way to fix this problem or maybe I should try replacing the modem?
Speed will depend on how many others around you are using WiFi. (The more people, even if on different networks, will congest WiFi signals, especially if on the same channel or those in close proximity.) Look for a channel that has the least amount of networks on it AND as best as possible, adjoining channels that have the fewest networks on them. If they are on the same or adjoining channels, the weaker their network signal to yours, the better.
The type of Wi-Fi you're using will make a difference too.... Wireless AC being the fastest and wireless B being the slowest (AC, N, G, B, A) You'll feel it more the slower your own WiFi (which is independent of your speed coming into your cable or DSL modem, (Cable in this case.)
Distance to the wireless router will have an effect too... try to keep the router centralized for the best even coverage.
Those things should help some anyway. Forgive me if you already have tried any of this.
