	This depends; compared to not using SQM you will loose some bandwidth, BUT the latency should stay nicely bound. The main improvement in a nutshell is that with properly configured SQM (with cake being the easiest to setup variant with lots of clever tricks under the hood) your link will still stay reasonably snappy even under saturating load. In other words the links keeps useable when you actually use it, most people consider the typically required bandwidth sacrifice of 10-15% for downstream acceptable…

	By the way, if I could convince you to post the results of the following commands run on your router via ssh:

cat /etc/config/sqm
/etc/init.d/sqm stop
tc -d qdisc
/etc/init.d/sqm start
tc -d qdisc

I would be delighted ;)

Best Regards
