I wish I could say that Unifi has just worked for me, but any time I add a new Unifi device to the network (say a new switch, or just recently a U6 range extender), my network gets incredibly unstable until I manually restart every UniFi device on the network, sometimes multiple times. (i.e. Some devices won't connect to WiFi due to DHCP IP configuration errors.) And that's after getting the device adopted, which generally takes multiple retries.

I've also had three instances where upon rebooting due to a power outage or a system update, my inbound firewall / port forwarding was just broken. UniFi simply did not pass packets to my server. Once again, a full reboot of every UniFi device on the network resolved it.

I really want to like UniFi, and I appreciate how much access I have to SSH in and figure out what's going on (and I did take tcpdumps and have a support case open), but it has definitely not been plug-and-play for me.

I'm using a UDR7, U7 Lite, a number of managed UniFi switches, and just recently added the U6 extender.

I just wanted to chime in and say that this hasn't been my experience. It sounds like you have some other sort of problem if it takes multiple attempts to adopt.

I appreciate the data point. It has truly been every single switch and now the extender as well. I'll open up a separate case for this.

The primary case I have open currently is in regards to the port forwarding / routing breaking on some restarts.

The 7 series has many problems. They'll eventually work it out, but it seems to be a bit more problematic than usual.

I do not have any of the 7 series yet, and perhaps that is the difference.

Sounds strange to me as well, ubnt has been the apple networking experience
