Quote from: patient0 on April 06, 2026, 05:42:33 PMi have some unmanaged 5-port switches. Netgear 1Gbps model and Netgear 2.5Gbps model. so i can do this test. What specifically am i looking to test by adding in the switch?Quite a few issues that come up here or on the other sense forum are between the upstream device and the router WAN. E.g. the upstream device is picky or is not as flexible as switch ports or a port flaps. Adding a switch would show if it is a specific issue of the two devices or not. Generally the routes WAN (and LAN) ports don't like the connected device ports flapping at all.
I'm aware that you have/had a number of devices that run well with the same upstream device and as a result the 3900 should behave well. The test would only be to narrow it down. It's of course also sensible to wait for help from Deciso.
