I have two laptop setups, both laptops are HP DF0023CL’s (3.0 USB ports) and two UD-3900’s.
I am connecting them to a Netgear R6700v3 router and getting 1GB internet service from CenturyLink
that has never measured more than 800mbps on speedtests. I am using cat5e or cat6 cables for the connection to the router. I have applied the latest Pluggable driver 9.3 M1 (version 9.3.3147.0) to both.
I am having the same problem with both setups. If I connect the laptop directly to the router I get download speeds generally above 700mbps. If I am connecting the laptops to the docking stations I typically get download speeds between 250-300mbps. That is quite a dropoff that I would like to close so I am approaching something closer to the 700mbps speed.
