PC can't find WiFi

[Brandcwh22]

I have 2 networks: wifi@unifi and wifi 5g@unifi. My phones can connect to the wifi 5g@unifi network perfectly, but my 2 PCs can't, they can't even find them in the list of available connections. I have a printer set up and connected to the wifi 5g network, so now I can't send documents to the printer. Please help.

Yep @Brandcwh22 , that is not aproblem actually.

You see, some devices cant recognize 5ghz spectrum. That is normal. Even some smartphone (like mine) cannot connected to 5ghz.

My suggestion is, either you change the printer network or use lan cable.

The thing is that it used to be able to connect. Now it just can't be detected

If you can used it before, then something might changed. What brand is your printer? With model number. I want to try googling around.

Your PC or smartphone is not able to decect the 5Ghz wifi because of the diffrence in the receicers most Mid-Range smartphones and PCs are not able to decect 5G wifi. i hope this helped you Have a good one!

P.S. Receivers such as 802.11n is able to receive 5G wifi.
