I guess maybe location has a bearing. My router is set to max all in a UK set up with BT as the line provider and Supanet as ISP. I can see definite changes when speed checking with this and other sites on the various tweaks, currently still using Apple Broadband Tuner it si about 10-15 k faster than Mac Pilot and 100 K faster than standard. Bt keeps altering my cap speed. I'll keep trying but thanks for the comment
