I managed to install LEDE on my V5 using alexvan's factory image and the lede sysupgrade image method.
The switch works perfectly. VLAN tagging works and I know it's very case specific but PPPoE auth for my ISP works too (once you figure out the correct configuration, see hxxps://forum.openwrt.org/viewtopic.php?id=71191)
Wireless is all over the place. If you change the mode, channel, width or transmit power from either 2.4ghz or 5ghz they crash and won't enable themselves. Encryption works though, I'm currently using WPA2-PSK with forced AES and it works.
He doesn't like low signal too. I'm either hitting 30-40 Mbps on my wifi devices or they straight up drop and reconnect. My phone is struggling with this a lot more than my laptop (which has an Intel 7260 AC adapter). They meant it when they wrote "Radios do not work reliably yet".
Overall I'm happy, next step is to get the official install image and better wifi support, then I'll probably fiddle with VoIP and SIP, which will probably be quite tricky.
