That seems plausible, and I was kinda expecting to that work,

r52054 - I had never touched the SFE setting before, but I just disabled it as you suggested, setup QoS, and instantly soft-bricked again. Rebooting the router does not help. Only option was to downgrade firmware via recovery as usual.

(If it had worked, I was gonna say, I've been using dd-wrt for years and whenever a certain version soft-bricked the router, it was always fixed in a future release. So this would've been a first, but, not to be.)

Did you wait long enough for the firmware to be upgraded?

Did you turn off then turn on the router after firmware upgrade?


I sure did! Will try again when I have time and do a full reset. Haven't done that in a good while on that particular router.

When I tried `service qos start`, SFE was affected:
Code:
~# service qos start
[sfe] : shortcut forwarding engine successfully started
~# tail /var/log/messages
...
Mar 21 15:41:33 DD-WRT user.info : [sfe] : shortcut forwarding engine successfully started
~#

According to the QoS guide in https://wiki.dd-wrt.com/wiki/index.php/Quality_of_Service ,
there should be svqos and wshaper. I found svqos to be a script as /usr/sbin/svqos,
while service wshaper was missing. I suspect service name "wshaper" might
have become "qos". I dunno for sure as I don't use QoS. The guide might have been too
outdated.
Code:
~# service list | grep -iE 'shape|qos'
        qos                     [start] [stop] [restart] (emulated)
~# which svqos
/usr/sbin/svqos
~# which qos
~# which wshaper
~#
# nvram show | grep -i shape
wshaper_enable=0
wshaper_downlink=0
wshaper_uplink=0
wshaper_nopriohostsrc=
wshaper_nopriohostdst=
wshaper_noprioportsrc=
wshaper_dev=WAN
wshaper_noprioportdst=
~#
~# nvram show | grep -i qos
qos_done=0
svqos_port2bw=FULL
svqos_port4prio=10
svqos_port2prio=10
svqos_port1bw=FULL
qos_type=0
svqos_macs=
svqos_port4bw=FULL
svqos_svcs=
svqos_port3prio=10
svqos_ips=
svqos_port1prio=10
svqos_port3bw=FULL
svqos_aqd=sfq
~#


The script /usr/sbin/svqos calls /usr/sbin/tc, where "tc" means "traffic control". There is nothing about tc command in DD-WRT's wiki:

Tc command - DD-WRT Wiki
https://wiki.dd-wrt.com/wiki/index.php/Tc_command

I suspect you can use your own script calling tc to do QoS, without relying on the WEBUI of DD-WRT. But you might need to mangle with the firewall script.

It also seems that tc might just be a command of Busybox? If so, you might wonder about the version of Busybox in use...

BTW, I wonder: could it be interface naming issue again? As some routers don't have wl0 but eth0. There is also no interface named "wan" as indicated by variable "wshaper_dev" above! Also you need to take into account br0, vlan1 and vlan2. Smile

Anyway, I think volunteers might be needed to really test QoS in various routers. Relevant documentation needs an update, too. Well...
