Link speed?

[mrgroot]

Just got an XA1 Ultra.... before that had a G4, which regularly stated link speeds of 433Mbps, same for my LG tab and my wife's S7 shows 866Mbps...so here I am with my XA1 getting only 135Mbps....??? Why would that be? It can't actually be a hardware limitation, can it?

Help please. I, too, have such a very small speed problem
, - - - z5 it shows 433 megabytes.
