Hi all,
I'm experiencing a recurring crash loop on one of the router's network instances, which causes intermittent internet outages for devices connected to the router, even though the LAN/Wi-Fi itself stays up.
Setup:
Router: GL.iNet Beryl 7 (GL-MT3600BE)
Admin Panel: v4.9.0
OpenWrt: 21.02-SNAPSHOT
Kernel: 5.4.281
Architecture: ARMv8
WAN source: USB tethering from an Android smartphone
Clients: multiple smartphones connected via Wi-Fi to the router
Symptom:
Connected smartphones intermittently report "no internet," while the Wi-Fi connection itself never drops (DHCP keeps working, other LAN-only devices stay connected/functional throughout).
Log excerpt (syslog)
::instance1 is in a crash loop 6 crashes, 6 seconds since last crash
This line repeats, with hostapd disassociation/reassociation events and errors like:
7993@ERROR.RA,ra0,UniCmdSetRecSecPnInfo() 6006: wdev is null!
7993@ERROR.PROTO,ra0,Peer_Vendor_Spec_Action() 982: frame len check error
happening around the same timestamps as the crash loop.
What I've tried:
Rebooting the router resolved the issue temporarily. The crash loop had not recurred since, but I wanted to flag it in case it's a known firmware bug with the USB tethering WAN instance.
Is this a known issue with the WAN instance handling USB tethering? Happy to share the full log or additional details if useful for debugging.
Thanks!
Marco
