Why can't I see my own 5G network but I can see my neighbour's?

So I'm using a desktop with a tp-link wifi adapter, I turned on my 5G network and try to see if I can connect on my desktop, but I'm unable to see the ssid of it (regular ssid +5g at end), but I can see my neighbour's regular 2.4g and 5g, both on 802.11n

I've tried setting my 5g as 802.11n and 802.11ac, but no avail.

Any ideas?
