on my network i experience a complete loss of signal a few times an hour, for about 1-3 seconds duration. usually it resolves itself, with the signal strength going from excellent to unavailable back to excellent, but sometimes i have to go into the properties and force a refresh for the network to become visible again. this affects both of my notebooks (fujitsu p2120 and compaq x1000, both with integrated wi-fi nics) at the same time, regardless of the distance from the antenna (about 10 feet unobstructed, hawking external high gain directional antenna). router is a d-link mr514. we *do* have seimens 2.4 ghz phones, but we took the batteries out of all of them and unplugged the power from the base station, stil without a noticeable difference. i don't want to throw more money at the problem blindly. any thoughts?
