Should the R8000 UI see devices connected via a GS308 switch?
In the supplied user interface, on the Basic tab, "attached devices/wired devices" area, should I be seeing any info at all (like status, IP, MAC address) for devices on a connected GS308v2 or is ...
You should see all devices connected to the switch

This is considered after the router, yes?
That's right. After all, you are asking the router to tell you what is connected to it.
Out of interest, but possibly relevant, what is this cable modem? Make and model?

I replaced the switch with a new GS308v3, changed to new cables and still can't "see" the devices on the switch.
All devices work fine if I connect them directly to the router but not on the (new) switch.
So, none of the devices that you add to the network through the new switch will work? Is that also the case for the old switch? Invisible and not working?
I ask because earlier on it was the invisibility that troubled you. Now it is that and the fact that they also don't work.
The cable modem is a Cisco DCP3008.
Sorry if I misled about "can't see/doesn't work". None of the devices on the switch are accessible via the network. But the type of devices made that difficult for me to prove to myself. A webcam's propriety software is unable to find the device, I'm unable to map a NAS, and I dont have access to the Dlink router installed by the security company to confirm connectivity. So I moved went from a lack of proveable functionaly to trying to "see" they were even connecting to the network by checking the router UI.
But I may have found the problem. I removed all the cables fron the switch and reconnected them one at time, stopping to check the wired device status on the router UI. This first device I connect did appear on the wired devices list and the 2nd one did too. But when I connected the 3rd device, they all disappeared from "wired devices".
I'm guessing the chances of a new cable failing in the same way as the one it replaced is highly unlikely but that appears to be what's happening. I'll leave it disconnected until I can get a new cable and will monitor to ensure all is well.
Thank you your help and for being respectful while I thought this through.

If that is the DPC3008 then that rules out some possibilities.

You seem to have homed in on the problem.Good research Sherlock.
You can narrow it down to the cable, and rule out the devices, by testing the third device with one of the other cables.
Maybe you did that.

Yes .. DPC3008 .. typo.
The location of the third device is farthest from the switch and I have no "known good" cables that long. But I might unmount the device and bring it closer or just wait to get a cable that I can always use.
Again .. thanks!

If possible, you could take another, more portable, LAN device to the remote end of the cable and see if that works.
Or disconnect and move the cable and use it to connect known good devices.
You will kick yourself if it turns out to be something other than the cable.
Again, maybe you tried this.
