I had not got around to trying the "atm"= =C2=A0 option in cake, which tries to compensate for cell size also. So you= should enable that - and I havent added support for it to sqm either!

Hi again

I tested Dave's build of cake on wndr3800.=C2=A0 (Didn't try sp= ecifying cake2/cake3; I'm guessing tc cake means cake3 on there).=C2=A0 &quo= t;atm" adjustment worked fine on my adsl.=C2=A0 I can't distinguish it fro= m sqm-scripts with the same configuration.

SQM seems to win from having "overhead 40", which I can't= configure in cake.

IMO it wouldn't hurt for 'tc atm', 'tc adsl', and e= verything else to default to 'overhead 44'.=C2=A0 (The highest overhead Seb repor= ted; the original worst case overhead[1] plus a vlan header for IPTV).
