[AFMUG] PMP450 ~50mbps cap

[Colin Stanners]

We setup a customer on a very lightly loaded 5ghz PMP450 AP and SM, 20mhz
channel, expecting them to burst up to 70mbit speeds for download; linktest
is reliably 85-90d and there's effectively no other usage. But we can't
seem to get over 50mbit speedtests. Has anyone else seen such issues?
