    Hi  

    Please login to SSH console and check for syslog and sysmessages.

    Please also check the Interface negotiation speed of the WAN interface with an upstream device.

    Please check the IP address added in the WAN gateway failover condition, The device will keep sending a request to that specific IP to check the status of the gateway if the request does not get a response for the configured time, it will trigger the alert of the gateway as down

    I had a similar issue with the gateway going down randomly.  I thought it was the modem but it turned out to be a bad ethernet cable.

    Hi Keyur,

    After SSH console I see details below:

    Sophos Firmware Version SFOS 17.5.8 MR-8

    Main Menu

    1. Network Configuration
    2. System Configuration
    3. Route Configuration
    4. Device Console
    5. Device Management
    6. VPN Management
    7. Shutdown/Reboot Device
    0. Exit

    Select Menu Number [0-7]:

    I can't find syslog and sysmessages from the subfolder of choice 1-5?

    Then I try top check the interface negotiation spped of the WAN interface with an upstream device.

    I can find some System graphs from Diagnostics of Monitor & Analyse:

    But I can't find the specific date / time of that port 2.

    At last, how can I check the IP address added in the WAN gateway failover condition?

    Thanks,

    Yeung Yan Ting
