Problems acquiring DHCP IP in case of multiple access points serving same SSID

[yanshay]

I'm developing for esp32 using esp-hal with embassy and face problems acquiring IP.
I have several TPLink Omada access points, and when several serve the same SSID the device fails to get the IP, or takes a lot of time (at least tens of seconds and even more).
When I leave only a single access point serving that SSID (others still work, just don't serve that SSID) the device gets the IP within a few seconds.

I discussed this in depth with the esp-hal team, and provided them with the relevant logs and they told me this part is handled by smoltcp.

The full discussion is available at: esp-rs/esp-hal#2345
Logs with some more finIngs available at: esp-rs/esp-hal#2345 (reply in thread)
Some more analysis: esp-rs/esp-hal#2345 (reply in thread)

And there is more relevant information on that thread which I don't want to copy here.

Any pointers as to how to troubleshoot this? Maybe it's a known issue?
