Expedition Navigation Software » temporary loss of network data

Probably not a Expedition issue but I have this problem that the connection with the network is lost from time to time.
The data is lost somtimes after 5 seconds, sometimes the connection is lost after a few minutes. But there is never a steady connection.
Connection is re-establisshed instantly after hitting the "instruments re-connect button".

Would anyone know hoe to solve this problem?
The network has always worked very well.

Maybe a router pproblem?

Many thanks!

I have had a similar problem which I believe is caused when the router/modem loses the internet connection. It seems that the modem is busy trying to find service and misses processing the internal tcp/ip traffic which results in expedition disconnected. I had the same problem with both wifi and hard wired connections.

It would be good if Expedition would automatically reconnect after a predefined period of time.

The websocket reconnection seems to be more reliable.

I've been looking at it today and found a case where it doesn't attempt to reconnect. I have fixed that and made the behaviour closer to the websocket for the next update.

I am still having this problem that the connection is lost from tim to time (but very reguraly).
Re-connection is done automatically in a few seconds but the connection is not steady at all.
Sometimes the computer crashes.

Could this be a firewall/ virus scanner issue?

Many thanks for the help.

What sort of connection is it? Ethernet, Wifi? What sort of instruments?

It is a network connecion. Instruments (old Raymarine), through multiplexer and separate router via Ethernet.
Or wireless through wIfI, but I found out that it doens't matter if I connect wireless or through Ethernet: The same problem occurs...
