Having difficulty in connecting to your wireless network anywhere in the house? No problems, if you follow what Bob Morris did in his house:

The offices in the new house are in a loft and the Wireless-G Range Expander for the linksys router did the job perfectly with the computers finding the wireless net easily. (Without the Range Expander, they couldn't find it at all.)

If you buy these two devices from Amazon you can get them at a rather inexpensive price. AND what is more, there is no wiring or other costs:

Unlike adding a traditional access point to your network to expand wireless coverage, the Wireless-G Range Expander does not need to be connected to the network by a data cable. Just put it within range of your main access point or wireless router, and it "bounces" the signals out to remote wireless devices.

Sounds too good to be true. But hey, it is true, I installed one today at home and now I can get my signal downstairs through a concrete floor.
