Tp-Link was just my current decision, but Netgear, ASUS, Dlink or whatever cold stand here, if they paid, I would have put it on more public area
Just for understanding, I bought my RB4011iGS+5HacQ2HnD back in 2019 due to port count and SFP+ uplink option. Was quite happy with features but also a bit frustrated due to non intuitive user interface. Noted, that I started with WiFi devices back in 2001 with first 802.11b devices and configured almost all major brands but ubiquiti since, even aftermarket firmwares like Openwrt, Tomato, dd-wrt and RouterOS was the one with highest learning demands and recherche for How-Tos since.
Bought a couple of TP-Link PoE APs, EAP225/245 to have overall WiFi coverage and wanted to power one via RB4011 PoE-out, which simply didn't work. This should ensure connectivity for smart connected devices during night, when unnecessary network is switched of for ppower saving reasons. As not unhappy with the router, I bought the CAP and HAP ac, which both worked on PoE out, but already spent an entire afternoon to configute CAP as access point, don't know for what reason this is a router by default. Spent the time to configure - unreachable - reset, configute again a little further - unreachable again, very frustrating. Same with HAP. As went on holidays, have overseen limit to return units and have them covered by dust during 2021. Needed another AP last summer, so flashed CAP to FW 7.4.1, configured as AP and worked this time for basic coverage, thus, WiFi performance being quite poor, more like 802.11g device.
Finally, after flashing RB4011 to every current firmware, I decided to also update CAP, as Release notes for new versions always wouldvirtual print on several pages. Just used integrated update option to do this. I returned about 20 minutes after starting update, unit had just ETH1 blinking and never got the unit beyond this so far. Spent another almost 3 hours since, trying different firmware and reset cycling without luck.
As meanwhile my hapiness with RB4011 vanished due to unstable WiFi connection and a couple of devices just refuse to connect to RB4011 WiFi, take some minutes to finally connect or even are not able to connect online on 2,4GHz WiFi thus connected correctly and router has almost basic configuration, I thought of alternative solution. As out of the last experiences, I'd also not unbox my HAP. Final decision to switch to TP-Link now was as Omada-Controller is now available as app for my Asustor NAS, so have just one management-tool in tjhe end that is also intuitive.
And also I am not willing anymore to read through endless tutorials on how to configure an AP as an AP and not router, as this is impossible to find out with 20 years of experience how to do it by simply walking through unit parameters and ending up on hours of trials and errors.
Nobody pays for this time, so I go for a solution that simply works out of the box after 2 minutes of configuration
So I hope I could explain the bullshit I posted before!

Thanks for hints, currently I have only SBC instances of Linux running and set-up a dedicated machine just for netinstall, as with virtual adapters for WSL / WSA on my productive systems that cannot set disabled it didn't work anyway. Netinstall finishes with success, but CAP still no reaction
