Windows 10: Looking for my 5 GHZ wifi network

Time ago, at the very start of my contract with my wifi network. I could choose from my 2.4 GHZ and 5 GHZ wifi easily from my computer (Windows 10) and my phone (7s) everything was good and I used to be connected all the time to 2.4 GHZ wifi. Nowadays I'm trying to connect to my 5 GHZ wifi through my phone and my computer and I can no longer connect my computer to that wifi service, It used to appear as a normal wifi network but now it doesn't, my phone can easily connect to it and work with it so I don't understand why my computer can no longer connect to it now. I tried to update and roll back my wifi driver and it still don't appear, I tried to make the wifi 5 GHZ connection to hidden and therefore try to connect to it and it didn't work. I tried a lot of things and it still doesn't.


I really need help because the 2.4 GHZ is too slow for the things I need to do and that annoys me!.

5 gHz Wifi

I installed a new Cable Modem Router that has dual band, 2.4 gHz and 5 gHz wifi. Everything works fine on my cell phones but when I connect to the new wifi, my computer does not see the 5 gHz wifi. I am using Windows 10 on a HP Pavilion g6. The computer
is more than 5 years old. Is there a way to get the computer to recognize the 5 gHz wifi, which is more reliable than the 2.4 gHz?

Windows 10 not finding 5 GHz wifi networks

since upgrading to windows 10 i'm only able to connect to my 2.4 GHz network at home, unlike with windows 7 were the 5 GHz network was my pc's default network. i'm finding no way to fix this issue so far, I've tried manually connecting and the router is
up to date. oddly i cant even see my neighbors WiFi connections anymore, only my 2.4 GHz WiFi comes up.
