Currently in the house we have set up a Linksys 54g router which sounded great at the time. But when i've tried to play (mainly) a First person shooter such as Counterstrike etc. I get irritating "lag spikes" as theyre called.
In other words the ping just rockets up too 999+ then shoots back down which you can imagine can be pretty annoying. Games were fine when i ran on a wired network with one PC acting as the hub (on at all times feeding the web across the network) and according to steam support its due to the wireless service.
Went to disable the windows wireless service but because I use the wireless software instead i didnt need to. Tempted to try wiring into the router itself, running a cable upstairs, to see if it works. Common problem?
