i have the hp elitebook 745 amd ryzen 3500u g6 laptop and i have it connected to an hp port replicator. up until a few days ago when i did a speed tests i got over 500 mbps up-dn. then yesterday it started to slow down now i'm getting 400 up and 500 dn. if i take the lan out of the port replicator and plug it into the pc it goes back to over 500 up-dn. so to prove out it is not the pc i plugged into the usb-c port a port replicator that does lan and monitor and i got over 500 up-dn.
so during those tests trying to get the monitor to work with one of my other usb-c port replicators i then plugged in the hp port replicator and the speed went back to over 500 up-dn. then maybe an hour later it was back down to under 400 up-500dn.
could that hp port replicator be failing?
can someone tell me if the hp elitebook 745 with the amd ryzen chips and the usb-c port that has d in a half circle and ss and the lan symbol run a monitor thru that port? the usb-c replicators i have say something about some pcs will not operate monitor thru those devices. but the hp port replicator is running a monitor. thanks
