Recently I haven't been able to connect to services such as most online games such as Minecraft servers, Dark Souls online service, etc.
I'm able to use the internet just fine otherwise.
I have tried using a wired connection, but that doesn't help
I have also tried on a different computer, with no avail
Disabling my firewall didn't work either
I have reset my router, restarted my computer, reset my winsock, etc. But nothing has changed
Hug?
"I have reset my router" - if you reset your router back to the factory defaults, this will have erased any Port Forward settings that may have been needed for online gaming, but would not affect normal Internet access.
When the problem started, it might be that the router accidentally reset itself to the factory state, possibly as a result of a short power glitch, or it might be that somebody reset the router without you knowing.
If you had changed the Wi-Fi settings from the factory state (many people don't bother) and had been using your own Wi-Fi settings, then Wi-Fi connections would have been interrupted by the reset, but not wired connections to the router.
Yeah, lots of people have that problem right now. Go look at the calendar on the wall. Check the date carefully. I think you will figure this out…
