DSL-2780 shows DSL line speed down as 10.1 Mbs
TT speedchecker shows download 8.5 Mbs
Q2: That is a normal feature of ADSL broadband, remember the "A" stands for "Asymmetric."
I wasnt referring to speed, but attenuation. Surley my attenuation should measure the same for both up and down as this is the line resistance back to the telephone exchange ?
