So I have a 2G wifi I can connect to and a 5G wifi I can connect to. I have always been able to connect to my 5G wifi, but as of recently, whenever I click connect on my computer, it says "Can't connect to this network". I am able to connect to my 2G wifi on my computer only. On my phone and other devices, I can connect to both the 2G and the 5G wifi without any issues. I am not aware of any changes recently made that would affect this. The only thing I can think of is that I recently got an upgrade for my internet, but both internet connections work fine on my other devices, so I don't think that that is the issue for my computer not being able to connect to the 5G wifi. I have tried several solutions including going into the wifi adapter settings and messing around with it, and reseting my router and modem. I feel as if the issue has started around when I upgraded my internet, but it works perfectly on other devices. Thanks for all the help!
