A few notes and observations.
First off, kernel 4.15 is very new and not all userland apps and services have been updated to be in sync with the new crda/regdomain/cfg80211 regime. In particular, network-manager is known to be in flux.
I supplied files in the regdb folder for those bold adventurers who wish to experiment with the new 4.15 kernel. The instructions are at the bottom of the page:
https://github.com/zebulon2/rtl8812au-driver-5.2.20
which is a direct clone of my git repo at:
https://github.com/gordboy/rtl8812au
In order to use kernel 4.15 you need the proper regdb files. Either from your distro, or from the repos above.
Second of all, probably the best way to see which wireless APs are visible is "wavemon". It is very robust and has few dependencies. Desktop applets are liable to lag behind kernel innovations, and give misleading results.
What worked for me was "wicd", in terms of desktop stuff. "network-manager" still has issues with kernel 4.15.
But what worked even better for me was not using kernel 4.15, and going back to 4.13.
Until everything is in sync, blindly upgrading to the latest shiny new kernel, is a mistake many hapless newcomers make.
