I am sure it is not coincidental, but 900 seconds is a very common default TCP timeout i.e. if no communication is received over the TCP connection in 900 seconds, then the TCP connection will be closed which could give the effects that you are seeing.

So the question is, why is no TCP communication occuring on the connection after 2.435 where it probably was before?

Personally, I would look to see if any firewalls are at play in the communication between the two devices and if so, temporary disable it. This assumes that one device is a PC/Mac and that you have control over the firewall. In your scenario, the router will not have any effect.
