Reuse the same connection in the R signal when navigating different pages

I have an MVC project with several pages.

I have a lengthy process that updates the client process. However, this update is sent only to one client, and is not broadcast to everyone.

Clients.Client(ConnectionId).sendMessage(msg);

In my layout.cshtml, this is how I connect to the hub

    var serverHub = $.connection.notifier;
    window.hubReady = $.connection.hub.start(function () { });

The problem is that when I go to another page, I no longer receive messages from signalr, because the connection identifier has changed.

How can I solve this problem, so my signalr concentrator can still send messages to one client, and the client goes from page to page.
