We have tried several different solutions for providing an Internet connection to my children's PC. We bought it for them to do their homework on and play games since they were tying up our other two computers (one used for our home based business). The problem was that we live in a very old and big house, making running cable very problematic. The obvious solution was wireless. We went out and bought all of the needed parts (all d-link), but the kid's room was *just* outside the range of the signal. Using the D-Link 2.4GHz Omni-Directional 7dBi Indoor Antenna ( ANT24-0700 ) solved this problem. It also took less than 1 minute to replace the old antenna with this one. This was just what we needed!
