Wireless dies, then comes back to life...

Hi guys,

Firstly, Windows7 Rocks.

But, when I startup, I have a good wireless connection, but aftre about 20 seconds, the network connection dies. My wireless indicator (Tray Icon) shows a good connection, but pinging my router (192.168.1.1) doesn't reply with anything. Not internet, not local network. Nothing. This lasts around 2 or 3 minutes, and then, by it;s self, it starts working again 100%, and works until I either restart, or go into power saving. When it restarts, same story. Networking dead for a few minutes, and then it comes back.

I am using a Toshiba M300 laptop, with built in Interl 5100AGN wireless device. I'm running Win7, Build 7022. All default settings since install.

Hope someone can assist.

Yeah, tried that/ No joy. Did it on the Wireless adaptor only though.

Actually - just noticed something. I CAN ping 192.168.1.1, but I can't browse to it. I normally can. Then, after a few minutes, I can browse again. So, the wireless is till alive.. Just can't browse/check mail...
