The 5 ghz network is not shown

[eaangrino]

I have a TP Link Archer C64 repeater and it has 5 ghz wifi, when I finished installing the driver of my tp link ac600 tu2 nano it does not recognize the 5 ghz network of my repeater, only 2.4 ghz, I changed something to support wpa2 psk[aes] in the repeater configuration, but it shows it for a few seconds and it does not appear anymore, but if I can see the 5g networks of other routers around.

I can connect to windows via 5 ghz.

It does not appear in ubuntu.

When I selected the wpa2 psk[aes] option it appeared for a few seconds but did not show up again, these are all the options.
