Unidentified 4mb Internet Connection after Ethernet to Switch pulled from Router! Mystery.

Just a mad latest update .... where to start?

After reading the good advice about Sonos & STP, we did some testing and checking. As mentioned, there are some well documented issues about mixed Sonos wireless and wired networks.

Anyway as part of this testing we measured the speed on a wired desktop PC to the internet with a long standing Sonos Play 5 connected to a port on the Netgear switch and then to router. This is what we saw .... ahh .... I can't see how to link an image from the PC I'm typing on .... strange. It only allows from media sources not the device?

Anyway, basically with the Sonos Play 5 connected we saw near 900mb internet connection at the desktop PC.

When we disconnected the router but the Play 5 still wired to the switch .... we still see 4mb connection to internet. But the Play 5 has no wifi or bluetooth functionality. It can be wirelessly connected to the network.

And when disconnecting the Play 5, and the router, there is of course no connection.

Very odd.

Sounds like you have network loops/bridges

You need to draw out your topology like what was suggested In the first post
 
Sounds like you've got some form of wireless bridge operating without you knowing. I wouldn't be suprised if this is a "feature" that's enabled by default. The topology diagram will help identify possible sources.

For example, as a temporary solution, I'm currently using a few Unifi APs as a bridge/mesh, which I think would look similar to your cable removed situation.

Could be, could be The wifi performance is excellent in fact. The Orbi devices are quite powerful and not so heavily used.

The topology in theory is quite clean, not so complex but nevertheless to do it well will take me a little while. I have a SW package I downloaded to try do it called Paesslar. But it's not exactly simple ... to me at least. I also have access to the Netgear Insight app/service that comes with the switches. But same again, I need configure it and learn a bit about it. If I can do that then I think both will create a network map that should prove useful. Just takes a little time.

In parallel I'm checking the small number of 8 port PoE switches that are attached the 2 x 48 port switches. These are often were things go AWOL. but so far the ones I've checked over look configured correctly.
