I would repeat that test a couple times to make sure. It would not surprise me that we also won on the dslreports tests for wifi for normal clients - dslreports does use multiple flows after all and the fq is going to help a lot here - but seeing bandwidth improve from 7 to 12mbits as a result of all this for that test, under these circumstances, strikes me as a bit much. --=20 Dave T=C3=A4ht Let's go make home routers and wifi faster!
