ESP32 disconnects every few hours from new router

Postby jp-nyc » Mon May 02, 2022 8:33 pm

Just replaced a standard Netgear router with a Linksys WRT3200ACM running DD-WRT v3.0-r48607 std (04/08/22).

The ESP32 has been reliably connected to the Netgear WiFi for many months without issue. When I connect to the DDWRT Linksys it disconnects and then reconnects every few hours. The log in the ESP32 shows it only disconnects for 3 seconds each time and probably takes 2.5 seconds of that time to reconnect, so it is just a really quick disconnect and then reconnect.

If I put the old netgear back in it stays reliably connected. Not sure if it is a hardware issue or DDWRT setting issue since I didnt test before switching firmware.

I'v tried to make the DDWRT WiFI settings as conservative as possible. I tried all 3 channel widths(20mhz, 20/40mhz, 40mhz), I tried B only, G only, N only wifi. I also tried changing the channel from 'auto' to a fixed channel since I'm in the heart of New York City with a lot of WiFi.

Any ideas?
(I'm also going to post on the DD-WRT forum)
