Hi, Thanks for the ideas. I was pretty sure it was device independant which is why this confused me. I’ve checked the counter on the iptables rule. The rule is being hit in both cases. I’ve used wireshark to capture the output. It shows the packets are correctly marked in both cases. However when I look at the counters in tc –s qdisc show dev $dev all the traffic in the wifi case is going to the default bucket, but in the wired case it goes to the correct bucket. The comments in the script below show the commands I’ve used to test it. Is there anything else I could be missing? A module not loaded perhaps? Anyone care to try and reproduce it with the script below?

Traffic control classification is device-type independed. Don't matter what kind of interfaces do you use. So, you have issue somewhere else. Check the actual classify rules and queue discipline and classes of your setup. Also check the actual dscp-value of outgoing packets with tcpdump. 2015-01-05 6:44 GMT+03:00 I-Strong, Russell J <Russell.J.Strong@xxxxxxxxxx>: I've been experimenting with HTB and have found that it works on a wired Ethernet devices but does not work on wireless devices. Packets are being correctly classified by the mangle table but are being placed in the default bucket when using wireless. They Are placed in the correct bucket when using wired. The script below shows how to reproduce it. Any thoughts? Is this a bug?
