@hoba: Actually this bug could derive from two for the next version already fixed bugs: 1. "no scheduler specified": earlier versions had support to select different schedulers. that support was dropped. The setting could be found at the advanced settings page. Due to a non complete removal this error could pop up if you save advanced settings AFTER you have run the shaper wizard. This is fixed in CVS 2. "qwanroot has no parent": This could be cause by not having a bandwidth set at your wan interface in the bandwidthfiled at "Interfaces>WAN". Please check that setting and set it to 10 mbit/s if you have a nic running at 10 mbit there or 100 mbit/s if the link is 100. This also is fixed in the new upcoming release and won't be necessary with this new version. So: Check WAN Bandwithfield, then run the shaper and don't save advanced settings after that and you should be fine for now….hopefully  ;D Next version won't need these workarounds. You are right I don't have it set!  I have been meaning to set that option too.  I don't have it set for Lan either so my traffic shaping is probably not working so well. I think I will do a clean install on the next version,  I just hope I can remember all my settings :). Thanks for your help.
