Windows 10: Overnight, Im no longer able to connect to 5g on my router, only 2.4 ghz is available

I didn't change anything on either my computer or router. Overnight, 5G suddenly stopped working. I thought it might be due to a windows update, so i rolled back my driver and installed again, still no dice. I can't see it on my 2 laptops or my phone. I've tried switching around the 5G channels on my router but no such luck. Is it possible that my router just s**t the bed, for 5G at least?

Cannot connect to 5g

Hi I'm Peter an independent advisor, if your trying to connect to 5g then you've got a router and network adapter that supports 5g (ie a virgin media router)? Qualcomm is your wireless network card....realtek is your ethernet adapter (physical network
port) for wired networks. If you want to connect to 5g open your wireless network available list and you should see the same SSID as 2g and one as 5g...just click on the 5g one.

 

Windows 10 doesn't connect to Netgear 36/36-5G router

Computer: Lenovo T520, O/S Windows 10 Pro, Router: NetGear 36/36-G,

Problem: Disconnected fm primary wifi network, NetGear 36, to connect to

NetGear 36-5G. To disconnect I called up network list and selected “disconnect”.

When unable to find & therefore connect to NetGear 36-5G attempted to reconnect

to original wifi system. Received message that computer can not connect.
Tried

all suggested solutions with no results, restarted computer, restarted router, tried to

restore computer to previous settings when computer worked normally, nothing worked.

Received error code 163851 which may indicate radio turned off in BIOS.
However, computer connects to internet successfully via different unencrypted wifi and via encrypted Hot Spot (wifi) on BB Z10.
So computer’s wifi radio is working normally.
Computer does not see the 36-5G side of NetGear router.
With Windows 7 Pro it did recognize that side and 36-5G was a valid choice for a connection.
When observing computer trying to connect see constant message “attempting authorization”.
Can not find anyway to check computer settings, SSID, Password, encryption key to confirm that the setting in my computer are correct for this wifi network.

Request help.

While using my desktop pc I see a 5G network available, but when I use my laptop, I only see a 2.4G network available. My router has two ports, 2.4G and 5G. Any ideas as to what I need to do to connect my laptop to the 5G network that does not show up
when I check networks available?
