PCWorld: How To Fix Wi-Fi Networking Problems
If you’re having problems with poor wireless connectivity on your small business network, start by downloading a free utilitiy such as inSSIDer to help you figure out what’s going on.
“I recently stayed at a Bed and Breakfast that offered guests two unprotected wireless networks. There were no other Wi-Fi networks in the area, yet the signal strength in my room was poor and Internet access was slow and spotty.
Windows does a miserable job of reporting on some important aspects of wireless networks, so whenever I need to get a better picture of the Wi-Fi environment, I turn to the free, open source, inSSIDer program from MetaGeek. inSSIDer runs on Windows XP, Vista and 7, both 32 and 64 bit.”
