Dell precision 5470 limited ethernet speed (DBQBCB064 adapter)
Precision 5470
Hi,
My laptop is running on Win11 and I have a 1GB internet speed.
When I'm on Wi-Fi, I reach 800MB speed.
When I connect to wired LAN via the Dell DBQBCB064 USB-C network adapter, I am stuck below 100MB.
In the driver properties I see that the link speed is limited to 100MB.
I've updated the driver, BIOS, everything I could - no change.
Dell support also have no solution...
Does anyone else have this problem and found a solution?
Thanks in advance.

Turns out that my Ethernet cable was defected.
Once replaced - the problem solved.

What type of switch and cable are you using? Is it a 10/100 switch, or are you using CAT 5 cables?

@ejn63 I'm using the Dell DBQBCBC064 Ethernet to USB-C adapter with a CAT5E cable
