Windows 10: "No Internet Access" Despite Being Online - Cannot Access Certain Services

PC Specs:AMD Ryzen 7 2700 Eight-Core Processor 3.20GHz 16GB RAMNVIDIA GeForce GTX1060 6GBGigaByte B450M DS3H WIFI-CFTo start off: This all began when all of my sound devices are nonfunctional: multiple AUX devices and Bluetooth. The extent of my efforts there was removing and reinstalling devices, to no avail. Eventually narrowing it down to a Windows driver update, I went to grab it out of my Optional Updates, and found that nothing I'd selected was downloading, and it just asked me to "retry" over and over again.That's when I noticed the issue of "No Internet Access". Which has been baffling

Unable to access internet with certain programs

I have a Compaq Presario CQ62 running Windows 10. I am unable to access the internet with a couple programs. I downloaded the update from Windows 7 to 10. Everything runs fine but HP's support program and Print Shop V22.

I googled the problem and tried some of the suggestions listed, but I still can't access the internet. I am using Firefox and it connects fine along with Norton Internet Security. Any suggestions?

No internet access

What type of security program/s do/did they have installed? I've seen McAfee and Norton both completely block internet access for no reason. Even after being uninstalled they can sometimes still block internet until you run their clean-up programs.

 

W10 can connect to wider internet but cannot access web pages

I have an odd issue with my W10 laptop linked to Sky broadband in the UK via wifi using a Sky router. The effect is that while I can actually access the internet (I can send and receive emails using Outlook and can connect to other machines using TeamViewer) I cannot access any web site (Google, BBC etc). There is no specific error message, merely that the access request timed out and a suggestion that it may be to do with proxy. I have tried the following:

1. Other systems (W10 and ios) can access web sites using the same Sky router (therefore probably not a router problem)
2. I have sent and received emails using Outlook, so the broadband connection is working (probably not a Sky problem)
3. I have tried two different browsers (Firefox and Edge), no connection (not a browser problem)
4. I am using Windows Defender and have:
   1. Made sure that Firefox is in the list of allowed systems in its Firewall, no connection after a reboot
   2. Turned off the Firewall and tried again - no connection

My next step will be to re-install Windows, but has anyone got any other suggestions? Could it be some sort of virus (I have carried out a complete virus check using Defender) So - any suggestions?
