So what I did was just: 1) open network connections 2) click properties 3) in the GENERAL tab, click INTERNET PROTOCOL (TCP/IP) 4) click Properties 5) choose obtain DNS server automatically My internet worked afterwards. I had to surf using an unsecured network server for the past months.According to my friend, this prevented me from connecting to the net despite having a wi-fi connection.Then if your operating system is windowsxp please follow the attachment to have a try.(they sent me a file attachment with the email) If your operating system is vista please refer to id=214 I have also seen WPA - Enterprise as just WPA.unless you are running into the initial problem that most older hardware had. You may need to do a firmware upgrade on your device that is connecting to the router. Firstly you can not use WPA, you can use WPA-PSK/WPA2-PSK or WEP.
Note: If your router has multiple ethernet ports, DO NOT use the WAN port to connect a computer.I recently bought a new Linksys wireless router and after setting it up with basic WEP security, I tried to logon from my laptop and was successful! So then I tried to connect from my desktop computer that has a wireless USB adapter attached to it and I ended up getting this error message: Fabulous! I checked my settings on the wireless router to make sure I didn’t accidentally setup certificate security, but found no such thing.Also, since I was able to connect from my laptop with no problem, it led me to believe it was something wrong with my desktop.After about 30 minutes of fiddling around with various settings, I was able to figure out what the problem was.Here’s how to connect to your wireless router if you are getting this message.
