I have an HP Omen (HP 15-dc1044na) laptop which has now become my primary work machine as my old desktop blew up.
I need the convenience of a dock so that I can move my laptop without plugging in a million cables and to drive my main display and after speaking to HP online chat, they recommended this dock.
I have a UD-ULTCDL dock which has:
4k HDMI plugged in (for ultrawide display - screen displays and works correctly)
Speakers (standard 3.5mm and work perfectly)
Various USB devices (phone charger, external harddrives etc… all working correctly)
I have a huge problem though with connectivity - whether I’m using the dock for ethernet or have ethernet plugged directly into my laptop or using wifi with the dock plugged in.
When the dock is powered on and plugged into my laptop and the ethernet plugged directly into my laptop (wifi turned off), pinging google.com is intermittent and very slow with my internet speed reduced to 0.2mbps. Without changing any set up and just turning off the dock, the ping quickly becomes stable and fast and my speed goes up to 16mbps.
Thanks for contacting Plugable support! I’m sorry to hear about this Ethernet issue through your Plugable UD-ULTCDL docking station, but I’d be happy to help.
Thank you for providing those pictures.
Sometimes a switch or VOIP in between these devices can cause network issues.
Can you clarify if the dock’s Ethernet cable goes directly to the router or modem?
Next, I’d like to have you temporarily disconnect everything connected to the dock (except Ethernet), then run the speed test.
That’ll help us rule out any odd peripheral contributing to this.
Next, You mentioned that you followed this KB article from DisplayLink. Would you be able to try the same steps but with the “Speed & Duplex” property, manually set to “100Mbps Full-Duplex” (instead of Auto Negotiate) to see if that changes the behavior?
CONFIGURING THE LINK SPEED
If these steps help, great! If not, I’d like to request some logs from your system to investigate further. Could you please keep the Plugable dock connected to your system (with the Ethernet cable still attached}, then navigate to our PlugDebug tool (https://plugable.com/support/plugdebug) and follow the instructions there?
Please email the results of the PlugDebug tool to firstname.lastname@example.org with “Ticket 330035” as the subject.
