My network speeds are 25mbit down with 1mbit up. I am using the provide cable companies modem which is a some Motorola docis 3 modem with a netgear 3700. I always have about 5 computers on the network at a time and sometime up to 10+ devices. When I moved here I added 2 computers to the network. They were using some decreped brandless router from the cable company. I could litterally not do anything on the internet without it being slow. I replaced the previous router with my netgear 3700 which really helped make hulu/youtube not buffer every 3 seconds and gaming. When everyone is actively using the internet it gets slow, for obvious reasons. Gaming wise I will sometimes have an excessive ping, like 300-500 more than I usually do. It makes me lag pretty bad. The router is in the opposite side of the house in the floor above me so I could not route an Ethernet cable easily to myself even if I was not renting. Is my router not enough? Do I not have enough bandwidth? Would a powerline adapter to myself help? Can I prioritize myself in the network with QOS or something else? DDwrt? I have tried using QOS to throttle the certain people but it does not work.
