Getting an Open NAT on Xbox 360 Wirelessly?

[Hell_Rell]

I have been going crazy trying to get a stable internet connection while using my Wireless Adapter on my Xbox 360. I can get the Open NAT but when i play things like Call Of Duty i constantly get “Connection Interrupted” as well as my connection going from ¾ Green Bars to 1 Red Bar.

I followed this guide as far as: Port Forwarding, Setting up Static IP, Adding my XBox’s Wireless MAC Addy to the Router Settings Page but everything ive tried has failed to give me a strong signal.

Could it be that my router is too far from the Xbox? Im using a Linksys E1000 router and have already given up and moved the PC closer to my Xbox just to avoid this, but id really like to have it Wireless.
