Both the DSl-AC52 and DSL-AC56U have the same MediaTeK DSL chipset, but the DSL-AC56U does have more RAM and is a good little unit.
Was you given a modem with your ISP service, what does the stats on this read?
Alas the Broadcom 63138 DSL chipset for ADSL is not ideal, maybe worth looking at an older Broadcom based modem/router?
For testing, try Annex A, just out of interest, I know in theory, Annex M should have more Upload Synch speed, but worth testing, ?
