    This appears to be a server issue, not a problem with your Mac. That's about all I can tell you.

    I guess I should have said it's a network or server issue. There's no obvious way in which the remote server could distinguish between clients on the same local network, which is what you seem be saying it does. The router could. Third-party routers can do odd things.

     

    If you want to try something exotic that almost certainly won't make any difference, try this.

    From the menu bar, select

    System Preferences Network

    If the Network preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Hardware tab. Select

    Configure: Manually

    and

    MTU: Custom

    Enter an MTU value of 1280.

    Click OK and then Apply. Test.

    You must apply the change before it takes effect.

    If the issue is resolved, experiment with higher MTU values until you find the highest one that works. The higher the MTU, the better the network interface will perform.

    If changing the MTU has no effect, restore the Configure setting to Automatically.

    earlier in the thread you felt the network was apparently ruled out

     

    "Apparently" is the key word. The facts you've stated since then don't fit any pattern I recognize.
