Unable to connect to WiFi: encrypted with WPA

Wifi Network security is meant to protect a wireless network from unauthorized access. Sometimes it happens that users cannot connect to a wifi network encrypted with WPA. The WPA encrypted Wifi Network asks for an authentication key before a connection can be made. If a valid key is provided and the user can still not connect to a wifi network encrypted with WPA, there could be a problem in the channel. Here's how to fix it.

What are the symptoms?

You cannot connect to a WPA-encrypted WiFi network even though it is listed and has a strong signal. It spends a long time establishing a connection before failing with an error message.

What configuration parameters do you need?

  • Freebox v5 in router and WiFi mode with WPA key.
  • Atheros WiFi card.
  • Windows Vista.

Note: this tip may work on other configurations.

What are the causes of it?

Channel 11 is the default channel in all configurations, which may have caused interference with the signal. Changing the channel should stop this.

How to fix it?

  • Go to the console for wireless management of your other Wi-Fi router.
  • Disable the automatic channel.
  • Select channel No. 10.
  • Choose an alphanumeric WPA key (using only letters and numbers).
