2 days ago, I was working on my PC and was about to open Chrome to check something, but it said that I had no internet. I checked my phone, which was connected to the same network, and it had Wi-Fi, but the PC couldn't connect to the internet. I restarted the router, waited a little, and after it turned on, the lamp for the internet was glowing red, and at that point I couldn't connect to the network via phone either. I figured it was an issue with my internet provider, as it tends to happen, so I waited about 4-5 hours. Since the internet didn't come back, I contacted my provider's tech support. The woman told me to use command prompt and ipconfig, and I followed the instructions, but it was to no avail. She said how the next day they'd contact me for further instructions. Yesterday, they contacted me and it turns out that the wifi works fine. My mom can connect to the network via laptop and I can connect to the internet via any device other than my PC. The ethernet cable is fine, I tried switching ports, I tried messing around with the network settings (they gave me instructions as to what to do), I tried disabling the ipv6 thingy, but nothing worked. My router works fine, my phone has wifi, my mom's laptop has wifi, but I simply can't get the internet to work on my PC at all. I assume this is a software issue, and I'm not sure what the cause is, but are there any suggestions you could give me? I'm thinking of reinstalling Windows or something, but I'm not sure if I should resort to such "drastic" measures and I can't help but feel like there's a way to resolve this in a simpler way. I should also note that I've tried restarting my PC and router multiple times, but nothing seems to be working.
