Router Probelm?

[Tok]

Ok I give the fuck up

backstory - couple days ago I noticed that I was sucking pretty hardcore in call of duty, I was emptying clips into enemies and not getting a hit..when the game ended i noticed that my connection was shitty, only had one bar. This went on for a couple days (and it happend on call of duty WaW as well)

today I swapped out my modem and retested it, my modem was kicking me off a couple times during the past couple of days, wasn't that, I went direct from modem to xbox and had perfect signal, so I totally reset my router and did a little tweaking in the configuration, enabled Quality of service and put my xbox to highest priority even, set all ethernet ports to high priority and released and renewed the DHCP lease on it. ran a couple tests and everything seemed fine for a bit, then i noticed after i put my fathers laptop back on my network that the signal was bad again, i disabled his wireless card, rinse and repeat and the signal was fine, got on call of duty 4 and played a bit and then bam, shitty signal again...turned off my mothers computer (so now the xbox and my pc are the only one using any connection at this point) and no change...

so I don't know if it's either my router now, or my xbox...i ran some ping tests from my router config page and i am getting some packet loss so it might be the router...but that whole %50 fail rate on xbox's could be a factor as well...either option is a shitty fuckin option cause my xbox is brand new and i don't want to replace my router.

any help?

Modem - Xbox = Good (note)

Modem - Xbox - Laptop 1 = Bad (note)
Is your father's laptop a zombie machine?

You should not have to mess around with QoS and expediting options.

When the problem shows up, slap a machine directly to the modem and run a bunch of pings and trace routes to make sure it's the router. If you're not experiencing packet loss then it is your router. If you are, then it's your connection. Unreliable connections from the WAN wrecks havoc on routing tables all the time and if you have DHCP/NAT setup on any home based router you'll experience a weird drop out and slow connections for no apparent reason (due to a unstable connection).

It's irritating, but good luck.
