Firmware Version

2.5.13

Description

After a period of time (6-18hrs, no longer than 24hr), WiFi enabled ESP32 based devices on are losing network connectivity (not physical connectivity, just no longer passing traffic). I have tested this with 2.5.13 and 2.5.14, but not older 2.5.x builds. I'm going to setup a heltec v3 for testing so I can capture console traffic. I'll post that here when I'm able to do so.

When the issue occurs:

• You can de-auth the node or power off the access point that it's connected to and it reconnects to wifi (same or another AP)
• When it reconnects you can see the node request DHCP and get a response (dhcp server logs)
• The DHCP exchange is successfully sniffed by my Ubiquiti setup
• Traffic logs (ubiquiti) show WiFi rx but no tx for the node during this issue

I am seeing this on:

• Two different wireless networks using Ubiquiti hardware
• One wireless network running off a Netgear Nighthawk
• Station G2, Heltec V3, and a T-Beam

Relevant log output

No response
