Issue with Xiaomi Mi Router 4A Gigabit Edition (OpenWrt 24.10.0) - Unable to Obtain IP from Modem

Installing and Using OpenWrt
1

Hello OpenWrt Community,

I hope this message finds you well. I am reaching out to seek assistance with an issue I've encountered after updating my Xiaomi Mi Router 4A Gigabit Edition to OpenWrt 24.10.0.

Issue Description:

After successfully updating from OpenWrt 23.07 to the latest 24.10.0 release, my router is unable to obtain an IP address from my modem. This issue did not occur prior to the update, and I have verified that the modem is functioning correctly with other devices.

Troubleshooting Steps Taken:

  1. Rebooted Both Router and Modem: I have tried power cycling both devices multiple times without success.
  2. Checked Cable Connections: Ensured that all Ethernet cables are securely connected.
  3. Verified Modem Functionality: Connected a different device directly to the modem, which successfully obtained an IP address.
  4. Reviewed Router Configuration: Double-checked the network settings in the OpenWrt interface to ensure they are correctly configured for DHCP.

Additional Information:

  • Router Model: Xiaomi Mi Router 4A Gigabit Edition
  • OpenWrt Version: 24.10.0
  • Modem: Hawai epon ont

I would greatly appreciate any insights or suggestions on how to resolve this issue. Has anyone else experienced similar problems with this router model or OpenWrt version? Any guidance on potential fixes or further troubleshooting steps would be highly appreciated.

Thank you in advance for your help!

Best regards,

Power off both devices
Power on pon cpe and wait until leds stabilise like 1-2 minutes
Connect openwrt wan port and power on xiaomi router, let it boot for a minute
Connect wired to open!rt.lan / 192.168.1.1 user: root, no password.
Go to network/interfaces and tell first 2 numbers of wan interfaces ip4 address.

Works fine for me (the upstream device is another router).

If what brada4 suggested doesn't work, download these packages

https://downloads.openwrt.org/releases/24.10.0/packages/mipsel_24kc/base/libpcap1_1.10.5-r1_mipsel_24kc.ipk
https://downloads.openwrt.org/releases/24.10.0/packages/mipsel_24kc/base/tcpdump_4.99.5-r1_mipsel_24kc.ipk

upload them using winscp to the /tmp directory and install them.

Then run:

tcpdump -nnvvi wan port 67 or port 68 & ifup wan; sleep 3; killall tcpdump
