My windows 10 computer suddenly got a problem with connecting to the internet. It started with my login pin not working, due to being offline. I then started noticing that most of the software on my computer could not connect to the internet at all, but some worked fine.
Working and not working stuff
Stuff confirmed not working:
- Windows login
- Windows Update
- Discord Client
- Twitch Client
- Edge
- Internet Explorer
- Kaspersky installation downloader
Stuff confirmed working:
- Steam
- Chrome
- Firefox
- Torrent client
- Plex server
- Ping in cmd
- Dropbox
Stuff I've tried that did not solve it
Other computers on the same network work fine. This computer tethered via USB to my phone shows the same problem. This leads me to believe the problem is in Windows.
Running both MalwareBytes and Kaspersky, both in premium trials. They found one or two threats each, but removing them did not solve the issue.
Rebooting the computer into Safe mode with networking.
Changing the DNS settings to either Google's DNS or
1.1.1.1.Disabling proxy settings in internet settings (they were never on).
Turning off firewall.
Disabling antivirus (only Windows defender installed when problem appeared).
Running the following commands in an elevated command prompt.
Commands:
ipconfig /flushdns
netsh winsock reset catalog
netsh int ipv4 reset reset.log
Other information possibly relevant
The day before my chrome acted up, showing clear signs of being infected by a malware, from god knows where. All my google search results were littered with spam links, and about half of the real links instead pointed to something called Search Feed Tech. After uninstalling some extensions that problem disappeared. But it seems to much of a coincidence to not be linked. Again, MalwareBytes did not find anything.
I have not been able to install windows updates for several months. Every time it tries to install an update it crashes with an error code, resets the update, and reboots back to normal. Searching around for that error code seemed to be a problem with missing DLLs from the N version of my windows. Have not been able to remedy that.
