Hi,
After a number of modem connection issues, resolved by updating to the latest RUTOS firmware, I'm still plagued by the following performance issue: The RUT955 I use has ~210 devices connected, almost all are statically assigned, connected by ethernet via a bunch a switches.
What I am seeing in about 10-20 of the devices is a necessary persistent TCP connection failing ("timeout" according to the devices) where I'd previously never had a problem, and a basic ping to those URLs seem to have no problem.
When I restart a handful of devices that have lost connection, they usually establish successful connections. But what I see at the destination server end is that this causes a handful of other devices to lose connection, so that there is always ~15 devices with timed out connections. It is like Whack-a-mole- restore some bad connections, and others get kicked off instead.
Looking at Live Data>Connections, there are about 600 connections at one time, with ~700 reported peak. What is the maximum connections that the 955 can handle?
I'm wondering if by incrementally adding devices, I have now reached a limit of the RUT955?
As an additional data point, I have an RUT240 with its own subnet and mobile connection as a failover, but connected to the RUT955 via Wifi for its primary WAN.
The ~30 devices on the RUT240 subnet do not have this TCP connection timeout issue. Only devices on the RUT955 subnet are showing this problem.
