I recently encountered above problem when connecting my personal ASUS netbook to our office network. I used to be able to do so without any issue until yesterday. My other colleagues have been able to do so without problem. I tried resetting the adapters and rebooting. I also tried to stop Bonjour services. ipconfig /renew didn;t work as well. Another thing, I don'have this issue when I am connecting to my wireless network at home.

I would suggest that you contact the system administrator for the office network and confirm the correct settings to access the network. SSID and password. Perhaps you need to update the drivers for the wireless adapter in your computer. Does the wireless adapter support the security protocol being used on the office network?

Hi, If your problem just happened with the special network, It should be caused by the setting between your laptop and the wireless device. I suggest that you may run CMD, then type the command ”ip config -all”, press enter. Copy the result or take a screenshot, and post here.
