Win 8.1 Lost Internet Connectivity

Topic

New Reply

I have a networking issue with Windows 8.1 that I hope someone can help me with.

Up until Saturday morning all was fine. Then, after I ran JV16 Powertools on my desktop Dell 8700 (that is connected to the router via Ethernet), I lost my internet connectivity.

The cable modem is fine, as is the router. Wi-Fi is working fine from other laptops and iPads in the house.
Even when I go into safe mode on the Dell 8700, I have internet connectivity. But when I boot into windows normally, I don’t have the internet access. I also don’t have access to the NAS drive that is connected t the router (I can successfully access the NAS via Wi-Fi from other laptops). I can also successfully print to the network printer (via WiFi) that is connected to the router.

I tried restoring from an earlier version of Windows. That didn’t help. I tried diagnosing using Windows built in help. That didn’t help. I think there must be some deep down setting that is preventing the PC from talking to the outside world. And, of course, I have checked the Ethernet cable to the router from the Dell.

Please help. I don’t know what to try next.

Thanks

Doesn’t JV16 make a backup file of what it changes?

See if How do I fix network adapter problems? or How to reset TCP/IP by using the NetShell utility help.

Usually when you can get Internet connectivity in Safe but not in normal mode, it’s usually a security program problem or another 3rd party program conflict.

If you still don’t get connectivity in a clean boot then I would look to your AV program or any paid for scanners, as they are the only type of programs that can reinstate themselves in a clean boot.
