I am living in a 3 story house and the wireless doesnt reach to the top floor very well, we are with talk talk and have a pc down stairs plugged directly into the adsl router and i have a 2 gaming pc's on the top floor, me and my partner are trying to play wow on these 2 machines together, i have a powerline (sends signal through elecricity cables) to eithernet my pc and the other one we tried wireless but get no signal, so i looked on the internet and saw i can use my spare router as a switch, so i tried that and hey presto it works i can run both pc's via eithernet or one eithernet and wireless up stairs, BUT when i log 2 pc's on upstaires the internet drops on the pc downstaires, this pc is her dads so i cant really steal all his internet . so is there something i am doing wrong or something that will aloow me to run all 3 pc's on the internet at the same time. the 2 routers are both talk talk and both have the ip address 192.168.1.1, if i put that IP into the upstairs pc's it loggs ontop the main router downstaires that is supplying the internet but if i do it on the pc downstaires it logs onto the router/switch upstairs?????????????????
do i need to change any settings? the router upstaires has 4 ports the one down only has 2.
please help as im really stuck, im not computer savvy so in lamen terms please
