What is the laptop using--802.11a, b, g, n, or ac?

What is the Jessie system using--802.11a, b, g, n, or ac?

(I/m not sure how you can determine this--maybe the LInk Station has a 
"maintainance" screen you can access?)

(Also, the Linkstation has to act as a repeater between the laptop and Jessie 
system--I'm not sure how much that might slow the transfer.)

Anyway, note that the theoretical throughput of 802.11b is 11 Mbps--your 880 
KB/s is reasonably consistent with that.  IIRC, 802.11g can do 54 Mbps, I'm 
not sure about the others.
