Hello!
I observe the following issues of which I think are somewhat related to my QMI Cellular device wwan0 / interface wan1 and the DNS settings:
- After booting the router I can reach any webpage for ca. 1 minute, afterwards every request times out
- I open the interfaces settings for
wan1and set "Use DNS servers advertised by peer" to "0" and enter some known DNS servers into "Use custom DNS servers". After applying this setting I have connectivity again. Even though I'm saving these settings they do not get persisted after a reboot (?!) - After a couple of hours (ca. 10 hours) HTTP requests do not work, a simple click on "restart" of the
wan1interface makes it work again
The modem seems to be working fine at any point.
I'm sorry if I can't provide more information at this stage, it is very hard for me to understand where the problem lies, especially as there is no error message or significant logging message I can observe.
I'm running the following setup:
Modem Quectel RM502Q-AE (4G/5G)
Architecture MediaTek MT7621 ver:1 eco:3
Target Platform ramips/mt7621
Firmware Version GoldenOrb_2023-08-02 ( OpenWrt 22.03-SNAPSHOT )
.. and here are some more informations which might hopefully be useful:
