I wanted to diagnose why my wireless hub range was so poor. If you have Windows 7 (or Vista) then you can use the following handy tool;
- Open Command Prompt (e.g. start->cmd)
- in the command windows type, netsh
- show networks mode=bssid
Then you can not only you move around and measure the signal strength but also see if there are any other wireless devices using the same channel as your hub.
