I'm looking to install a single UniFi AP AC Lite which I already have, sitting unused. I just want to use its 5GHz radio w/ multiple SSIDs and VLANs and also 802.11r for quick transitions between APs (the other "AP" is actually a Netgear R7800 running OpenWRT in AP mode).
I have a few questions please:
Should I stay with stock firmware or flash it to OpenWRT? For a single AP, dealing with the UniFi controller is overkill (and the mobile app is terrible just very basic settings). But that might be the true and tried firmware version that has many deployments. Not sure how well OpenWRT works on it and what version to use. The attraction of OpenWRT is that I can just use the WebUI/ssh which I'm familiar with from my R7800.
I'd like to use the same SSIDs/VLANs as on my R7800, to improve coverage in a corner. Any ideas if 802.11r will work well between these 2 devices? The backhaul is wired, no mesh or repeater, though not sure if a mesh helps in any way with a wired backhaul and what I'd need to do, if it even has a chance with these 2 different devices.
I assume that I want different channels, e.g. use ch 36 on the UniFi and ch 149 on the R7800. I'm also thinking of turning down the power on the UniFi, I just need some better coverage in a corner (which luckily happens to have an Ethernet drop).
