Duet 2 Wifi incompatibility questions

jayarmstrong

It seems the ESP8266 / ESP-12s doesn't work with certain routers, including my brand new one (which uses Qualcomm IPQ4028 https://www.qualcomm.com/products/ipq4028 )

Can the ESP-8266 firmware be updated?
Does it currently require WPA2 TKIP?
Is there a list of incompatible chipsets?

Same issue reported here: https://forum.duet3d.com/topic/14993/cannot-connect-duet-wifi-to-new-wifi-router/18

Thanks

@jayarmstrong is there some documentation (maybe from Espessif) about the incompatibility? I compatibility should be possible as the SoC you linked said it supported 802.11n

Had a similar issue.
Was running Ubiquiti WAPs in Dual mode, 5ghz and 2.4 together on the same SSID.

Created a pure 2.4 SSID with WEP encryption and my problem went away and allowed me to connect.

@jayarmstrong you could try the DuetWiFiServer-duet.bin version from here https://github.com/gloomyandy/DuetWiFiSocketServer/releases/tag/V1.26-01
this is built using a newer SDK than the one used by the duet releases
