Hi Kaywess,
I suggest you to update the wireless card drivers and check if you are able to open the web sites. Please visit the following link and enter the system Service Tag in the “Yes” section and click “Submit”:

Click on the “Network” section on the download page and download the wireless drivers listed. You will need to check the security software blocked website settings, if the issue persists after installing the drivers.
Please let me know if you need further assistance.
