Hey, I have a Dell Inspiron 17r SE. It comes with a Intel® Centrino Wireless-N 2230 adapter. Every 5 minutes or so, I lose internet connection. I run the trouble shooter, and it resets the adapter, saying the default gateway was not available. It happens so often, I don't know what to do. In the advanced settings menu, I can't get the 40 hz band. Only auto, or 20 hz. Please help me! Thanks a lot!
