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.
