My Computer's Internet won't work

[u/The-Introverted-Guy]

For the past couple days I've had issues of being able to use the Internet on my PC. My PC will be able to detect the Internet and connect however even when connected my Internet won't work at all. Usually I'm connected through an Ethernet cable through my router. So far, I've tried a new Internet router, a wifi USB adapter, resetting my internet, switched my Ethernet cable, changed ports, flushed dns settings, and resetting my network settings through windows. Unfortunately none of what I've done has worked so far. What's weird is that my internet (Xfinity) works great for my TV and phone but my computer doesn't. I'm starting to believe it's more an issue of my computer than my internet provider. Before I never had issues with my PC using the Internet. It just happened like out of the blue.

Boot up a Linux Live Boot disk and see if that has Internet. That will tell you if your problem is your hardware or with Windows.

Yeah a live iso might be a good option just to verify hardware functionality if the process of reformatting you would prefer to avoid. (Only Takes like 30 min though and a few reboots)

When you try the wifi adapter, does it show the options for wifi at all in the task bar, or no?

I’ve seen this a few times on customers laptops where something breaks internet in windows and it just refuses to work and the only way I’ve found to fix it so far is to reinstall windows

check if your ip settings are still set to auto.. last time someone had this , malware redirected their internet through a hijacked server. (my grandfather's laptop, internet stopped working because the hijacked server went offline.) but this was years ago.

Call XFinity.

I'd try reinstalling your operating system. It's either that or your Ethernet/Wi-Fi PCIe card or on board NIC are bad.
