Desktop Wireless and Networking

Hi everyone! I’m hoping somebody can help me with a Wi-Fi connection issue I’ve been having for about a month now. I have an HP Envy All-in-one PC and currently have updated my system up until the 16th of June. The problem I’m having is every time I turn on my monitor, my Wi-Fi never automatically connects like it used to. I have to go into the Network and Internet settings and select my Wi-Fi router. When I do, it usually works for about two minutes tops and then disconnects again. When I try to reconnect, I get the “Cannot connect to this network” error. I’ve tried to use the ‘Get Help’ feature and follow the all the given prompts, reset both my router and PC but nothing seems to work it does look. My wifi works completely fine with all my other devices in my apartment and the wi-fi app says the connected to my PC is strong as well. It seems like I’m behind a couple updates so I’d like to think that’s the reason, but I can’t download updates unless I’m connected to Wi-Fi!! I’ve also tried to connect to another Wi-Fi router that I had the permission to use, but then I proceeded to get the same error that says “Cannot connect to this network”. I’ve tried searching for solutions all over the Internet, but nothing has worked so far. I’m completely lost on what to do at this point. I don’t want to have to take my computer to a tech, just for them to do something that I could’ve done at home in five minutes!! Any help would be so greatly appreciated !!
