Windows 10: 5Ghz Network Issue

Now I've searched online and have seen the typical response of "update the drivers" or "enable 802.11n mode" and both have been done. Now my issue is mainly that I can connect to my wifi's 2G network but not the 5G network. Here is where it gets weird. 1: Windows CAN see 5G networks fine as I am detecting my neighbor's 5G wifi fine as well as other 5G networks. 2: The router is not at fault as both my cellphone and my mother's both run off the 5G network perfectly fine. 3: I only lost the ability to connect to our specific 5G network after updating windows from version 1803 to version 1809. 4: I know for a fact that windows remembers I have a 5G network as when I go to "Manage known networks" under the "Wifi" section of the settings it shows it remembers my 5G network. Which device is at fault here? How do I fix this? All other solutions I have tried have failed so I come here hoping someone may have an answer. Thank you for your time and I look forward to a response.

My 5GHZ wifi network is no longer appearing.

I have been connected to my 5ghz wifi network for a while around two days ago it disappeared from my list of available networks but is still on my known network.

In order to fix the issue i have:

-reset my router

-uninstalled and reinstalled my network adapters drivers

I am not to knowledgeable about network issues, and i know the 5ghz wifi connection is available and works because i am using it on other devices and the connection is fine and fast.
