I'm looking for a new OpenWrt router. Based on your great ToH, I managed to break down my selection to 8 devices:
Linksys WRT AC Series: WRT1200AC, WRT1900AC V1 and V2, WRT1900ACS, WRT3200ACM, WRT32X
ZyXEL NBG6817 (Armor Z2)
I live in Germany and I have a 120 Mbit/s internet connection. My needs are:
stable and open source wireless driver for fast 2.4 and 5 GHz wifi
high stability and software maturity in general
Because I'm a linux and open source addicted nerd, there is a big chance that I will not only use the router as AP.
Right now I don't know what exactly I'm planning to do with the router, so I would like to buy a powerful device that can handle some "advanced" stuff in the future.
Did you find a resolution to the random reboot problem?
I'm having random reboots and slowdown on my Netgear R6400v1 (running DD-WRT) and have been looking at my options for a new router and running openwrt. Was about to order the NBG6817 until I read this message.
No, 19.07.3 will not magically fix the issue in stmmac (and it should affect basically all ipq806x devices, not just the nbg6817) - kernel >= 4.19 will, but that (respectively v5.4) is only in master/ snapshots (~what will become 20.xy.0). A fix might be backported, if the changes that actually helped could be identified (git bisected), but there's been a lot of work on stmmac recently (and ongoing), so taking a lucky guess won't be possible. This would need to be investigated by someone who is affected (I'm using a nbg6817 since early 2017, I've never seen it myself).
Yes it was the Apr. 1 snapshot when I tried. And I still see people having same issue as of 5 days ago so I am a bit afraid to give it another try...
edit: I finally got a snapshot installed, will update thread if restarting issue is resolved! It usually happened every 2 or 3 days so if I can go 2 weeks without it happening I think I can say its fixed.
Confirming latest snapshot has seemed to have fixed the issue so far, over 6 days and no crashes which is almost a record for me. If I can get to 2 weeks without a crash I will consider the bug fixed, but so far it is looking VERY VERY good. (I used to crash every 0-2 days minimum).
So, at this point I feel comfortable recommending the NBG6817 IF you are comfortable flashing the dev. snapshot. Otherwise, I would not.
