DP83848-EP: Regarding turning off auto negotiation

Part Number: DP83848-EP

Tool/software:

Hello, Evan

Thank you for your advice.
I have a similar question.

You are considering Auto-negotiation mismatch between link partners as one of the possible causes of the problem you are experiencing.
If this is the actual cause,
if we turn off auto-negotiation on both ends of the LAN cable (PC and peripheral device) and fix the communication specifications (communication rate, terminal specifications, etc.),
won't this prevent the kind of situation where the link cannot be established?

We are considering turning off auto negotiation as a countermeasure for this problem.

Best regards,
tsuji

  • Hi Tsuji,

    If auto-negotiation failure is the root cause of this issue with link down, then I agree that fixed speed with auto-negotiation disabled is the workaround.

    Please do test this and confirm if the issue can still be observed.

    Thank you,
    Evan
