Why won't my PC connect to WiFi after moving to a new house?

I recently moved from an apartment to a house and switched my internet provider from Xfinity to AT&T Fiber. Now, my home PC won't find any WiFi signals, whether it's from my new router or even my phone's hotspot. I've already reset both my PC and router, and I've played around with the device settings, enabled WiFi, and reinstalled the drivers. Other devices like my phone and tablet connect just fine, but my PC seems totally clueless. I've checked my PC tower for a network switch I might've accidentally bumped into, but I can't see anything out of place. My PC has always been reliable for connecting to networks for the past four years, so this sudden issue is really puzzling me.

Also, if you're using the 5GHz band, try setting the router's channel to 44. That might help with connectivity issues.

Don't forget to check that the WiFi antenna on your PC is connected properly. Sometimes that's an easy fix!

I understand your frustration! Sometimes, not all Wi-Fi adapters work with all routers. When I switched from Xfinity to AT&T, I had to get a different Wi-Fi adapter because my setup simply wouldn't recognize the AT&T networks. I went with one from Amazon that works great with my new router.

CuriousCactus21: Thanks for the tip! I'll definitely consider getting a new adapter if I can't resolve the issue.

Have you tried doing a Network Reset? You can type 'Network Reset' into the Windows search bar, and that might help solve the issue.

Head to the device manager by right-clicking the start button. Check under 'Network Adapters' to see if your network card is listed. If it's missing, your card might have failed. If it's integrated into the motherboard, you're kinda stuck, but you could grab a PCI-E network card if you have room for one.

It sounds like it might be a hardware issue. Have you opened up your PC to check the network card? Make sure it's securely plugged in and look for any signs of damage.
