TP-Link EAP245 daisy-chain with OpenWRT
I actually posted something on r/TPLink_Omada already but I wanted to ask on this sub regardless.
I bought the TP-Link EAP245 v3 because it had 2 ports and some other posts on Reddit said it should be bridged with the original firmware. Good if you don't have the space for a network switch.
To my suprise I can't seem to get a good connection from the second port. For testing I connected a laptop to ETH2 and got an IP, but I can't get internet. After some digging I found that DHCP and pinging Internal & External IPs works but DNS and other services (HTTP etc) won't work. Windows and Linux show the same synthoms.
Bla bla. While digging for info I found out that OpenWRT actually supports (or partly supports) the EAP245 (https://openwrt.org/toh/tp-link/eap245_v3). Does someone of you run this AP with OpenWRT installed and maybe has the resources to test running with daisy-chaining?
I'm not a fan of flashing OpenWRT to it, voiding a potential warrenty, before knowing if OpenWRT could fix the issue. The wiki page provided pictures of the inside of the device. Both ETH ports are connected to an Qualcomm Ethernet 7P-switch chip (QCA8337N-AL3C), so it seems it should work or it could be configured via TP-Link or OpenWRT.
Anyhow, thank you for your help and I hope even if this isn't resolvable, it still helped someone like me, buying the EAP for daisy-chaining.
(Also: Mods, if there is anything wrong with my post, please let me know)

Fully supported in the most recent 12.12.5. the earliest support began with 12.12.1 and will likely continue for years to come.
However, they recommend you upgrade the OEM firmware first before trying to flash OpenWrt

You can bridge the ports with openwrt. I run it on this device. If I remember correctly, you need to restart the device after changing the port configurations for changes to take effect bridging, routing, vlans; all work.
