Cannot connect to home wifi directly with PC, can connect via phone hotspot

[emothxughts]

I have a weird situation right now, where I cannot connect directly to my home wifi network with my PC, because it will instead throw an "unable to connect to this network" error message. Sometimes it can connect, then hours later I am disconnected and cannot connect again. My phones are able to connect to the network, as are the rest of the household, including the TV.

 

The weird part is this: My PC is perfectly able to connect to my phones' hotspots. This would normally gobble up my mobile data, but if I turn off mobile data and keep the hotspot on, I am able to access the home wifi network as used by my phone, making my phone a wifi relay. In fact I am connected to my old spare phone with no SIM card to post this. The speeds are slightly lower than connecting directly to the home wifi, but still faster than my mobile data, so it's definitely (indirectly) connected to the home wifi.

 

So why then can't my PC connect directly? I have restarted the router, restarted my PC, forget the home wifi on my PC, I still can't connect directly. Is it because there's too many devices directly connected to the router?

 

(My wifi PCIE card is the TP-Link AC1200 Archer T4E)

Have you tried updating the drivers for your network card? Make sure you have all default settings, ip address, dns servers, etc.

The easiest solution for this though is always ethernet if you have access to it.
