Using netgear wifi router, sometimes with 3 computers online at once. Downstairs neighbour uses our wifi. Is a serious gamer (Call of Duty) Will this slow internet on the other 'puters
I would say the other computers will probably slow down the Call of Duty first instead of the other way around.
You can easily setup the netgear router to give priorities too. But i suspect your neighbour will be mad about Call of duty problems before you have speed issues on the 3 computers.
Depends on what speed of internet you have, but online games require much slower internet speeds, but require it to be constant.
If you can set your router to 'reserve' 0.5 mbps up/down for whichever device he plays COD with, that should make him happier.
