The DIR-636 RangeBooster from D-Link is a draft 802.11n compliant device. It supposidly runs 5x faster then the 802.11g wireless connections but yet is still compatible backwards.
It can in some cases provide a faster then 100Mbps signal. With the device you can create a secure wireless network in your home which makes file sharing across your computers a lot safer. It is also compatible with VOIP protocols so that calls can run smoothly.
