SMB - Dell environment with slow Ethernet speed on WD15 and D6000
-We are a 215 PC environment with mixed desktops and laptops that have found issues lately with speeds on our 80 mbps internet connect
-After troubleshooting I found that bypassing the docking station (Dell k17a) I could get full speed on the laptop -Thinking it was the K17A I replaced it with a Dell D6000 and found the exact same issue -After updating the BIOS, the Docking station firmware, the drivers and still getting the slow speed through the docking station I stumbled onto this forum - Went through the building and grabbed two random laptops and tested and found they had the slow issue as well -On the first laptop listed I have the BETA DisplayLink USB Graphics Software for Windows 8.5 M1 installed with no changes -I have also tried removing the displayport adapters converting to DVI and tried removing all monitors still getting the same slow speed -Here is my issue, I have LOTS of laptops deployed using these USB C docking stations with slow speeds on them including Dell tablets that I have to image with the docking station that are VERY SLOW -What are the next steps to provide more info in moving forward to either work with Display Link or engaging Dell as we are a Government\Public work site and I want to get this moving in the right direction. 1.Dell Latitude 5280 - This laptop I have tested with both D6000 and WD15\K17A D6000 and k17a -Driver 10.21.1012.2017 for the realtek usb GbE - NETWORK Driver -Latitude 5280 -Firmware 1.9.3 -Primary: DELL U2713HM -Secondary: DELL P2312H -When connected to D6000 or k17a ethernet speeds are 50kbps down to 8mbps -When connected to the laptop Ethernet get full 80mbps down 2.Dell Latitude 5280 D6000 -Driver 8.3.1728.0 Display Link Corp - NETWORK Driver -Latitude 5280 -Firmware 1.6.4 -Primary: DELL P2312H -Secondary: DELL P2312H -When connected to D6000 ethernet speeds are 500kbps-8mbps down -When connected to the laptop Ethernet get full 80mbps down 3.Dell Latitude 5280 -dell k17a \ WD15 -Driver 10.5.919.2015 realtek USB GbE - NETWORK Driver -Latitude 5280 -Firmware 1.6.4 -Primary: DELL E2211H -Secondary: DELL P2312H -When connected to WD15 ethernet speeds are 8mbps\8mbps -When connected to the laptop Ethernet get full 80mbps down Last edited by tmasazo; 06-08-2018 at 09:09 PM.
