I'm trying to setup a DD-WRT router (www.dd-wrt.com; embedded micro-device
linux for the uninitiated) to rate limit all the traffic it receives from
its wi-fi interface. I followed the instructions from the cookbook section
on rate limiting (http://lartc.org/howto/lartc.ratelimit.single.html), but
it doesn't appear to be working. I tested by checking my laptop's bandwidth
on http://www.speakeasy.net/speedtest/. Here's the commands I issued to tc:
# tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit
# tc class add dev $DEV parent 1: classid 1:1 cbq rate 512kbit allot 1500
prio 5 bounded isolated
# tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip src
192.168.1.0/24 flowid 1:1
I replaced $DEV with each interface name in succession, as I wasn't sure
which to use. Here's the output of ifconfig from the router:
# ifconfig

Can anyone tell me what I'm doing wrong here?
