Regarding linksys routers: If you are experiencing problems with it, and none of the above fixes are working, it is because the product itself is flawed.

I searched through many a customer review on the linksys routers and have found two things in common

1. Customers praise ease of installation.
2. The product sucks anyway.

Don't buy! It's cheap but not worth it! I've spent 140 bucks on two of them only to have them not work. I quickly fixed the problem by equipping my pc with a brand new wireless network card ^_^

If you don't handle SP2 correctly, it'll screw with you more than you know, learned the hard way :P


There's always the "manual hard labor" fix for these kinds of problems as well.
It involves unplugging the router at the first sign of trouble and plugging it back in after ten seconds... repeatedly...
