BleepingComputer.com: wireless network intermittent problems

My neighbor installed wireless security cameras and it is messing with my wireless network. We have narrowed it down to his cameras. He was kind enough to unplug them for 24 hrs and I had no problems at all. As soon as he plugged them back in my wireless goes intermittent. At times my wireless network is completely lost. I have a Net Gear router (wireless G) and have no problems with it until he plugs his cameras in. I did go buy a Link Sys Router (wireless N) this did not fix the problem so took it back to the store. Can anyone tell me how to block my across the street neighbor wireless network so that mine can work?

Thank You

One thing before we start: You're sure his cameras are connecting to his wireless and not yours? Just checking lol

It sounds like there is a channel issue. If you surf into the router there will be wireless settings.Its normally on the same page you set the SSID and what band it is using. You want to change the channel from Auto(this is where it normally is set) to a specific number. If you talk to your neighbor you might ask if he specified a number so you don't pick the same. You may also have to change this on your PC's wireless card settings.
