Hello,

Have you tried forgetting your wireless network and then re-connecting to it? Have you checked that you are typing in the correct wireless password?

What is the make and model of your laptop? Do other people use your wireless as well?

If not then change the wireless encryption from WPA2 to WPA and try connecting again.

Also, your Xirrus image isnt very clear. Can you try and re-post it?

Your wireless adapter is disconnected check it is turned on or not disabled in device manager.

Try deleting all the wireless profiles.

Then try and re-connect to your router ssid.

xiaoyue · 02-10-2012, 06:28 PM

i just format my pc , so it is empty now. no matter i enable/disable the WPS , my pc and iphone still cannot connect the wi-fi. anyone got any idea about that ?

**this-IT-guy** · 02-10-2012, 07:45 PM

WPS only concerns devices that are WPS compatible, it's a feature design to provide easy wifi access. Since you've formatted your PC, double check and make sure your wireless network configuration is the same as your router's wireless configuration. Same goes for your iphone.

Same network name, password, and security/encryption type.

Since re-formatting your pc have you installed all the hardware drivers for all your hardware such as chipset drivers, audio, video and Lan and wifi drivers?
