[   23.256674] Rebooting in 1 seconds..

The 07-05 build of 21.02, ath10k, definitely chokes up for me after about 6 days of continuous use. It starts to randomly disconnect phones.

Trying 07-31 build...

Using the July 5th build of master, uptime isn't as stable as the June 18th build. Last few days a spontaneous reboot, while this same build with configuration also lasted about 2 weeks before spontaneous reboot. I have no clue whatsoever of the reason. Syslog is going to my NAS, but as is expected; a spontaneous reboot often is so fast there's no network connectivity anymore to send something to syslog over the LAN.

Is there a way I can retrieve a reason for this spontaneous reboot without attaching some sort of console cable? Can I make OpenWRT save crashdumps on a USB stick for instance? And; would that be of any use to us?

I just left the sysupgrade file in the bin folder. That router is unique and doesn’t have a factory file when you build. Do you need the initramfs.bin file?

maybe not needed,but I can try yours . I used before is snapshots initramfs.bin

Just hooked my router on the 6/18 build into my new apartment's gig fiber connection and, well, yall are incredible for making this available. Still totally stable - had wifi go down the other day for some reason but it booted right back up

@ACwifidude Would you consider accepting this pull request so that NFS is included in your future builds please - https://github.com/ACwifidude/openwrt/pull/1

After almost 50 full days of uptime, curiosity got the best of me :slight_smile:

Compiled the image 21.02 from the @ACwifidude's repo and flashed it without wiping the config.
2 hrs later everything still seems to be stable. Fingers crossed for similar stability :slight_smile:

That said, in the last few builds my upload performance is slightly lower that it used to be.
I would typically get 940M(D)/930M(U), now it is 940M/880M. Any ideas?
I've tested this with multiple speedtest servers at different times. Even tested with the original Netgear FW, which gives full 940/940 with the same speedtest servers

Don’t know. I have an asymmetric WAN (940/35) so the upload is always “good”. :grin:

Must be a change in master. Would be interesting if 21.02 was the same.

@ACwifidude, not sure what it is but there is no difference in wire line speed test results between 19.x and 21.x. Both show 940/880. Is there any QOS turned on by default?

No qos. Everything is default settings except for this one tweak:

Does the performance governor get you to 940/940?

That is with the performance governor

Could be your ISP throttling uplink speed. Are you able to try local LAN-WAN iperf 3 test?

I have tested the same with the Netgear FW, I get 940/940

IC. IMHO tho. using Internet servers for speed test is going to be hit and miss sometimes, tho. I cannot explain why using the official firmware give you full speed, while using OpenWRT with the NSS cores enabled is slower. Interesting.

Are you able to test using iperf 3?

I'll look into it, but i'm 99% sure it'll be the same. I used to get 930-940 both ways with OpenWRT as well.
I understand that speedtest can be a hit an miss, but this is constantly the same across builds for the last few months. I'm not upgrading often, I prefer stability over latest and greatest, so can't really tell when the slight degradation started. It is not a big deal, we are after all talking about 5% less performance on upload. Would be nice to squeeze out that too :slight_smile:

Regarding the speed I post this just for comparison.
Yesterday I've installed the latest R7800-20210731-MasterNSS-ath10k image.
This is what I get with my 1000/700 Mbps link. I get the same speed with the latest Voxel firmware.
Screenshot (235)
What are the differences between the ath10k and ath10k-ct, at least for the R7800?

He contributed something, which is half I know. is the wifi driver, the cr is "upgraded" by a third party company, or something like that. but it can give other types of problems depending on which Wi-Fi devices you use. I hope I am not wrong. he he
