SG135 slow internet connection

Sophos User6847

Hi all,

We use two SG135 - FW 9.712-13 with completely identical config (really 100% identical) and identical fibre internet connection 300/50.

At the first SG135 iv'e get the full internet speed but at the second SG135 the downspeed is limited to approx 60mb down (upspeed is ok).

If i connect directly to the ISP modem i get the full downspeed of approx 300mb.

I found here in the community a similar problem with the information that IPS was the problem.

So far so good, but when i turn off the IPS setting i get approx 100mb down instead of approx. 60mb but  the rest 180mb downspeed are still missing.

I also deactivated QOS, ATP, etc. including reboot of the device but doesn't change the situation

Did anyone here have any suggestions what i can try else?

    Ok - crazy situation.

    Setting is on auto negotiation for all ethernet ports,
    cli says - for some unknown reason -  link mode is only at 100 currently at he the "problem" sg135.

    At the other SG135 also auto negotiation is on but link mode is 1000.

    I guess i found the problem, but i don't understand why he handle out a slower link mode at the other SG135.
