    Wired connection works on Laptop, not Desktop (Daily, Intermittent)


    Howdy All,

    I am having an issue with desktop work computers that will not connect to the internet via Ethernet cable.
    When I test the same cable connected with my laptop, the internet works flawlessly.

    The desktop issue usually only comes up once a day, and for around 30 minutes. After this time, it just magically works again. During the down time, I can still access the work intranet site and share drives, but cannot connect to external sites.

    We don't have many desktops but strangely this issue has come up twice for different users in the past week (probably coincidental).

    Any guidance would be greatly appreciated!


    Thanks for your time,
    Andy

    Hi andyfromcali. Welcome to the TenForums @andyfromcali

    Is it possible the routers has old rules for when access is not permitted and along with that, the router has IP reservations for specific Mac addresses, or the desktops are using static addresses that meet these rules IP addresses.

    So in router a rule is present to restrict access for 192.168.1.10 from 12:00 to 12:30.

    Are all devices running the same AV and no extra privacy or connection software. (VPN''s as an example)
