Windows update issues

+1

If your wireless router has a built in firewall maybe it's somehow set to block the ports that Windows updates use?

I'd also suggest if it works with it being directly connected then you could try resetting your router to see if this fixes the issue.

That's my 2 cents anyways. *Smile

 

Internet through wifi connection

Hi Sammy,

A few possible reasons can cause WiFi connection issues. To help us identify the cause of this problem, we would like to know the following information:

• Can you connect to the WiFi hotspot of your router? If yes, what is the status of the connection?
• Does your laptop automatically connect to the WiFi? Do you need to type a password when connecting?
• Can your laptop detect other WiFi hotspots around your location?

In the meantime, let's run the Network troubleshooter while connected using WiFi. The Network troubleshooter can help diagnose and fix common connection problems. To run it, follow the steps below:

• Click Start.
• In the search bar, type Network problems, and then select Identify and repair network problems from the list of results.
• Follow the steps in the troubleshooter and see if that fixes the problem.

Keep us updated on the status of the issue, and we will be glad to assist you further.
