Hello
I've been using dd-wrt for some time now and I have TP-Link WR842ND V2 with r31544 installed.
it works fine, most of the time.
Sometimes (like, several times a day) it keeps restarting and I don't know what to do.
I've tried with different dd-wrt versions:
28444
29059
30432
30471
30534
30880
31544
31571
It's always the same.
I have 3 PC's in my wired network and 5 phones on wireless.
I've set all devices to static IP and as soon as I use QoS, thing get tricky. Bit even if I turn QoS off, the problem remains.
Anyone have any idea on what to do?

there is newer builds yet, try them all.. setup syslog & if u can, visually watch the memory usage, is free ram usually close to 0?

[inside83]

thank you for your swift reply.
I'll try latest available, 31825.
Which one is free RAM?
This?

[tatsuya46]

yes

[inside83]

I installed 31825. but still, as soon as I enable QoS, router goes into a reboot loop.
Free RAM is usually 4-6 MB
This is the log:

You can see at 16:18 it starts a reboot.

[tatsuya46]

do u already have any settings entered in qos other than the (empty) defaults?

[inside83]

I experimented a little and as soon as I enable QoS with these settings (image bellow), router freezes/goes into reboot loop

[tatsuya46]

try htb and uncheck all ack priorities

[inside83]

I did and now it does not reboot that often.
But as soon as I add a service priority rule, it doesn't last 5 minutes.
I added two service rules:
- torrent (custom rule): bulk
I forwarded a port for torrent and added a custom rule just for that port.
- httpvideo (built in rule): maximum
I added httpvideo rule for watching videos with kodi.

Basically, I want not to worry if I have torrent active on one of the PC's when I'm watching movies and TV shows on Kodi on another PC.

dont use l7/ndpi, use custom port entries, services are old buggy not maintained properly etc & eat lots of cpu. eg: add an entry for port 80~80 tcp only = same as http, etc for other stuff.
