Sold out yet againThat makes me want to rush out and buy some TP-LINK HARDWARE ASAP! /sarcasm.
Or you could take your toiletpaper link router and repurpose it as a WAP behind a new unifi cloud gateway ultra ($129)
Cloud Gateway Ultra - Ubiquiti Store
Powerful and compact multi-WAN UniFi Cloud Gateway with a full suite of advanced routing and security features.store.ui.com
Probably available for twice the price on Amazon.
I think this device is the ideal replacement for those of us who started with CloudKey and the USG-3P. Unfortunately I can't seem to get one.
