Time to talk to your PC's maker how to factory reset and try again.
So, since day one i've had UPnP problems with my computer.. I just cant figure out how to make UPnP work. Games usually show its Strict.
My router is Huawei b593, and it says i have the latest firmware.
Windows 10, and the network drivers are up to date too.
To start it off, yes, i have tried with other connection sources like sharing a connection from a phone, different routers and whatnot but the problem still exists. I've tried port forwarding my routers aswell without any good results. My router firewall has been disabled completely and i dont have other firewalls than windows firewall. Ive tried enabling IP-helpers and UPnP services from my computer, tried most of the things on windows's sites about the topics aswell but not knowing if this actually did anything since the problem still persists.
Also, i noticed that my computer says i'm missing internet protocol sockets, but resetting them with netshell did nothing for me (it was succesfull)
Any more info and details you may need to help me better, feel free to ask. I've tried most of the things google offers me so i decided to come and ask people first hand about this problem. Also, sorry if my english was bad, it's not my native language.
