Problem Description

We are building smart garage door opener with ESP-WROOM-32 module. Everything went well. But recently, with the increasing number of devices that we sold, more and more reports came from our customers that their devices can not connect with their router. (All the Routers in the reports are provided by Arris, for example Arris DG2460 and Arris TG3452A/CG).

We came to some of the customer’s house and did some basic investigation. We found:

1. The ESP32 failed to get an IP address from the DHCP server of Arris Router.
2. ESP32 can connect with the router(STA_CONNECTED event triggered), but failed to get IP address from the router( The GOP_IP event never get triggered).
3. If we set the router to OPEN(not encrypted), ESP32 can get IP and work properly.
4. If we set the router to any of the encrypted mode(for example WPA2), ESP32 CAN NOT get IP from the Arris Router.
5. For most routers from other vendor, ESP32 can work properly.

Expected Behavior

Connect with Arris Router and IP assigned.

Actual Behavior

STA connect with Arris Router but fail to get GOT_IP event before ‘TIMEOUT’.

Steps to reproduce

Just try connecting ESP32 to a Arris Router

// If possible, attach a picture of your setup/wiring here.

Code to reproduce this issue

BluFi example in IDF. Or sta connect example in IDF.
