Hi Jay,
Dell Wireless 1490 card supports the WPA2-PSK security type for wireless connections. You may delete all the existing wireless profiles from the system and create a new profile with WPA2-PSA security key. Please follow the steps below:
- Open Control panel, select and double click Network Connections.
- Select ‘Wireless Network Connection’, right click it and select ‘Properties’.
- Choose ‘Wireless Networks’ and select existing network in preferred networks, then click ‘Remove’.
- Click OK.
- Then select ‘Wireless Network Connection’, right click it, select and click ‘View Available Wireless Networks’.
- Click ‘Refresh Network List’ to view available wireless networks. Select the correct network which you want to connect, double click it or click ‘Connect’.
- If the wireless network is secured, it will pop up a window asking for the key/password.
- Enter the correct Key then click ‘Connect’, wait for a while, you will connect to this wireless network.
Hope this helps. Please reply for any further questions.
