Massive rubber banding/ping spikes in Battlefield 2 on G73JH

Don't know if this is the right place to put this, but here goes:

I recently got a new 802.11n wireless router and now my Battlefield 2 is unplayable on my G73JH due to massive ping spikes every 30 seconds or so, which causes the so-called "rubber banding" effect. I'll be running along just fine at <50 ms ping and then suddenly I'll spike to 300 back-and-forth for a few seconds and my screen goes herky-jerky. As far as I know my new router is configured perfectly because the signal strength remains stable and strong even in-game when the spikes happen. No other game that I have does this to me. This happens on all BF2 servers, even the ones with very low ping. I'm completely stumped. Could this be an issue with the game itself? I'm running Windows 7 64-bit.

 

you could try port forwarding and see if that fixes your issue, also try playing directly using the modem and bypass the router, if the rubber banding still occurs then it maybe your modem or ISP if not then it's your router.

 

I don't know what port forwarding is. I've already bypassed my router and it's fine on just my cable modem. Weird thing is my router is perfectly fine on every other application except Battlefield 2.
