  • Device problem occurs on: Netgear Nighthawk X4S R7800
  • Software versions of LEDE release, packages, etc.: LEDE Reboot SNAPSHOT r4173-5d48dc1146 / LuCI Master (git-17.141.68918-5ca3864)
  • Steps to reproduce
    Boot device, wait for it to crash within 24hours

The paste ending in Hn was recorder after wifi stopped working and i turned wifi off and on.
The paste ending in Wu happend about 30 minutes after that and could only be resolved by rebooting the device.

I can confirm that the wifi (5 GHz radio) is unstable and readily crashes the router in LEDE master (I tested with r4658-4787e1960) on this device. LEDE stable works properly.

Data throughput is also very low (download in particular), and stressing the connection randomly crashes the router. Just changing wifi settings also frequently causes crashes.

@DragonBluep do you think, this is related to the Sercomm Partition Table? If so then, this could be closed now, right?

I'm sorry I have no experience with Sercomm Partition. The ath9k and ath10k drivers will copy the calibration data to rootfs. As far as I know, R7800 uses ubifs as rootfs, and this file system is very stable.

It has been six years since this issue was raised. Maybe it has already been fixed.

I'm not sure whether ubi likes the underlying data layer to be shifted. regardless:
Back then stable wasn't affected, which it likely would be with issues related to the sercomm partitions.
I agree, it's been years and it was likely fixed.
@hauke please close this issue

This commit might've fixed this (unclear)
