A network speed tester lets you test the speed of your wireless network, too. You can get information about your wireless network to make sure it’s properly configured–for example, pinging your configured DNS server and gateway to confirm that they’re active and working properly. Xirrus Wi-Fi InspectorA similar tool for troubleshooting wireless networks, Xirrus Wi-Fi Inspector (also free) offers even more information than InSSIDer does about each wireless network it finds. Then you can solve the problem either by moving your router or by moving the PC from the poorly served location. You can also walk around your office or home with InSSIDer on a laptop, and see the signal strength in all locations, to find dead spots. That way, you can determine whether a nearby network might be generating interference, and change your channel. It searches out every wireless network in an area, shows the signal strength of each, and shows the channels that each one uses.
