We have a KR1 with a Kyocera 650 aircard with remote antenna. We use the wireless portion to talk to two laptops and one printer. When we bought it, it was the only wireless router. When it works, it works great, but it will not stay connected via the aircard for more than 20 minutes. Then you have to unplug it and restart.The dropping of the line is signal independent. Some areas the dropping is every 1-2 minutes others 15-20 minutes but it never stays connected. It also sometimes broadcasts its ssid and other times it doesn't.Based on input from others the problems we've encountered with the KR1 are inherent in the design. Software upgrades don't seem to work. We have just ordered a new D-Link DIR-450. We know D-Link collaborated with Kyocera on the KR1, and some folks speculate the DIR-450 will be just as bad. But we have talked to users that say the DIR-450 doesn't drop the line.
