Problem with Networking: Help

[andvruss]

Recently, I had 2 computers in my house networked. It was all fine, but then on of them disconnects and says a connection cable is unplugged. Then another section says it is unavailable. I had a 450 MhZ computer networked to a 2.4 GhZ one, and this connection worked for a while, sharing the same high speed internet. But then the slower one says it is unavailable, and I checked all the cables around 3 times on each computer, and they are plugged in. This is using a 22 Mbps Wireless Broadband Router. I don't see how I could've somehow disable the connection via my computer or another other such programs. Can anyone help me?

Unplug the router and plug it back in. Unplug your modem and do the same thing.

If this problem still occurs, then set up networking on the 450 mhz machine again.

Check the cable to see if it's been cut/damaged.

Ok, I called the company that installed it, and they gave me some instructions. They said it might be fridge interfering with the wireless reception. I will have to see how it is now......
