Who I have the same questioned this solution

In my own testing, E3200's Broadcom WiFi 6 radio is more robust than CR1000A's Qualcomm radio and CE1000A's MediaTek radio. CR1000A's WiFi 6E radio is better near 940Mbps peaking for 5 minutes.

I don't know what issues would E3200 have with CR1000A. E3200 has lower speed ports than CE1000A.

The LED thing, you might need to reboot the CR1000A, not the CE1000A to resync the settings. The SSDP re-broadcasts after a reboot.
