Yes I saw this sticky.1 of 5 PCs stopped connecting to the WiFi router. It had been working for some time.The SSID appears in the list as "Automatic". Click connect and it spins for minutes before stopping without error message. Nothing appears in the event viewer. Virus scan says clean. I can run an Ethernet cable to it and it will work. This has been going on for a month. Since it's used occasionally by a 9 year old I've let it go. Another computer is doing it now too as of Saturday. We ran an Ethernet cable to the second PC and it will work. Recently the 9 year old had used this computer for school work. Her computer (1st one) had been working fine until sometime after starting to do homework on it. Of course it could be something else. Now it's two machines not connecting without error. Could to be related to something she is inadvertently doing. Any ideas on troubleshooting? 1 person needs an answerI do too

Once you connect to a wireless network, details of that connection are often saved as a "profile" under your wireless network application and re-used the next time that wireless network is encountered. If that profile has been somehow altered, the default information retrieved may not be sufficient to authenticate to that connection at a later time.Look in your system tray for your wireless internet application, double-click on it or otherwise launch it to the screen. Look for a "Profiles" button and open the profiles window. Then delete all the profiles that you see there such that there is no longer a history for an attempted connection. At a minimum, delete the profile that is associated with the SSID that you are trying to connect to. After that, try re-scanning and reconnecting to your network.HTH, JW
