I had a WRT54G ROUTER thinking it was causing the lag spikes but after buying a new router, a wrt541g, I find out that is not the problem.

My internet connection is 3m/512k. I play a game called Crossfire which is at z8games.com. My ping is around 30ms at all times when no one else is on the computer that is hooked to my router. However, when my mom gets on Facebook my ping spikes LIKE mad, it will go from 30ms to 350+ in an instant and makes the game completely unplayable. Anyone have any ideas on how to solve this? This only happens when mom is on her computer too, it should probably be noted that she plays Farmville.It wouldn't let me edit the post for some reason but here is a ping test.



That is while my mom is not on it and when she is on it the jitter jumps up to around 100 or so randomly and the ping goes through the roof. Also I made a mistake on my first post, it's a wr541g not a wrt541g.What's the network topography like?  Are you on WiFi?

Tbh, it's GOING to happen anyway as the router has more LOAD to deal with when more devices are using it.

Anyway, try running a trace route to a couple of different places next time you notice the problem.

Such as (without the qoutes) the following in a command prompt (Start -> Run -> CMD):

"tracert -d www.google.co.uk"
"tracert -d www.bbc.co.uk"
"tracert -d www.microsoft.com"
"tracert -d z8games.com"

Post the results back, and we'll be able to see where the lag kicks in. 

(Note: When I tested z8Games, there were a couple of routers that had noticably high times such as 300 ms)
