Missing in Windows 8 is the ability to view and delete all wireless profiles from your PC.  For some unknown reason Microsoft removed that feature which is very problematic if you ever need to edit a saved profile or delete one. I recently had an issue with a wireless access point that had a hidden SSID.  I had to manually setup the connection but I forgot to check the box to connect even if the network is not broadcasting. So I was able to connect the first time but all other attempts failed because the network would not show up on the new wireless charm list. When I would try to re-add the profile again using the manually create wireless screen it would fail because there was another wireless profile with the exact same name.  Since Microsoft tore out the GUI t delete and edit profiles, I was stuck. After some research I found that there is a command line utility that will let you delete profiles.  To use that follow these steps: Open up an admini...

Fix Connectivity Issues It sounds crazy, but 95 percent of all Internet connectivity problems can be solved by power-cycling both the router and the modem. Turn them both off, and then turn the modem back on first. Once its "sync" or signal light comes on, turn on your router. Use Encryption You've probably heard this before, but it bears repeating: Always enable your router's wireless security! Wired Equivalent Privacy (WEP) encryption is the oldest (and weakest) form of security; the newer (and stronger) Wi-Fi Protected Access (WPA) and WPA-2 are the best protection available today for home users. Update Your Router's Firmware All routers include internal read-only chips with embedded instructions that can be updated by the manufacturer. Router manufacturers generally update a product's firmware to increase performance as well as to resolve bugs and security issues, so it's wise to keep your router's firmware up-to-date. C...
