Connection Cycling

Hey,
I've dealt with this problem for a long time and I'm getting pretty frustrated. Using a Toshiba Satellite (laptop) A305 running Vista Home Premium x64. Checked my router and internet connections using other non-Vista laptop and wireless connection - no problem with them.

When the internet runs, it runs like a charm...

But...

Seemingly without warning, internet connection will disappear. Tends to go from Internet Connected, to Connected to Router (but no internet connection), to Not Connected (even to router), to Connected to Router, to Not Connected, to Internet Connected. All of this doesn't happen in a regular or predictable manner (including how long it takes to go through the "cycles").

Normally, if I leave the computer alone for a few minutes (15-30), it will go back to full connection.

Makes me want to through my computer against the wall at times. Please help?

Let me know if there is any additional information you might need.

Jay
