[LARTC] rate limiting netmask w/ dd-wrt

["Ryan O'Toole" <rotoole@gmail.com>]

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:

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