Query: Doesn't work with Motorola modem

We purchased this range extender to work with our Qwest Motorola modem/router. 1 of our laptops wasn't getting the wireless signal on the second floor of our house. After 5 hours of attempting to get the extender to recognize the router I came across a wiki that said that this is extender does not work with every brand of modem. It's not a universal extender, and therefore you can only be sure it will work with a Linksys modem. Buy a universal extender if you want to be sure it will work with your non-Linksys modem.After making a stop at our local big box appliance/computer store, we decided to just upgrade our modem to aNETGEAR WNDR3300 RangeMax Dual Band Wireless-N Router. It was one $169 item as opposed to a $99 router plus a $77 extender. The Netgear router solved our problems and increased the signal strength so that the problem laptop could connect upstairs, and there's only one unit to plug into the wall.
