wireless question....put on your thinking caps!

A very strange thing happened last night...but first off this is what I have for my wireless components:

Encore ENLWI-N card

Buffalo Wireless Router

I have flashed the router with tomato firmware and everything was working great for the past month. I started doing a little overclocking last night. All I did was increase my FSB so Q6600 speed was 2.5 instead of stock 2.4. I left the voltages at stock as well. Then it seemed my internet (just browsing to various sites) was going increasingly slow. My card showed 100% signal strength but loading any pages reminded me of a 28k dial up connection.

I changed the FSB and everything else back to defaults and still it was like this (after several reboots and a system restore). The webpage would almost load or load halfway then time out. I had trouble getting to my router web page as well. Using ping in command prompt, I'd get random time outs to yahoo and msn.com

I tried using another computer on my home network that is wired and this works fine, so did the same with mine; used my wired ethernet ports and browsing went back to normal. (If you're wondering, my computer is down a long hallway from the router and running a cable wouldn't work for long term).

Have any of you guys experienced something like this? I wonder if it is the wireless piece of the buffalo router that is not working properly or the wireless card in the PC. (I'd troubleshoot with a laptop if I had one). I assume this is hardware related....All my other specs in my sig. Thanks for any help!

Do you have speakers next to your router? That will cause timeouts, disconnects, and data loss. I'd try to clear the path between you and the router of anything that can generate interference. (Microwave, Speakers, Cellphones, etc) Also, try using the wireless at a different location in the house. If you're 10ft from the router w/ wireless on, then either the adapter on your computer is forked, or the router is having issues.

You can try updating the drivers on your wireless adapter, or at least reinstalling the existing ones to see if that helps.
