GS116Ev2 and GS105Ev2 speed issues
I have a strange situation that I cannot figure the cause.
I have had a GS116Ev2 switch setup with VLAN tagging and connected to several devices (including downstream GS105Ev2 switches) for a w...
Just to close this thread out...
I was finally able to resolve my issue! It seems that the installer didn't do a clean installation of the wall panel and left the connectors "noisy". By going in and cleaning up the work, everything is up. Thanks for the various suggestions!
I do have a switch question, though, but I'll start a different thread as it's unrelated to this...
Hi pcm0,
Welcome to the community! :)
How are the 3 switches (GS116Ev2 and 2 GS105Ev2) connected? Are they daisy-chained to each other? It would be best if you post an image or screenshot of the detailed network setup.

Hi DaneA,
Thanks for responding! I've attached an image of the setup. And, no, the 105s are not daisy-chained - they're edge switches connected to the 116.
Referring to the image:
Essentially, Rooms A&B (blue & red) were setup a while ago and were working fine. When Room C (green) was added, the link from Room B (red) dropped from 1Gb to 100Mb. This happens regardless of which actual 105 switch is used in the room nor which order the rooms are connected.
One other interesting thing I noticed - when either Room C or Room B is plugged into the 116, the switch turns on/off the lights on these connections in alternating fashion (B on for 10-15 secs, turned off, C on for 10-15 secs, turned off, back to B for 10-15 secs, turned off, etc). I notice that it only happens between these 2 room connections - adding/removing Room A (blue) doesn't seem to impact any of the other ports on the 116.

This does indicate some loop or similar odd wiring problems - ensure the four pairs of each connection have no interconnection to the other room.
Double check there are no devices concurrently connecting to the wired and to the wireless network, e.g Sonos in these rooms.I got a chance to do run an experiment where both of the downstream 105s were disconnected from any end devices and only the switches were plugged in to the 116. The results are the same, which makes me think I am getting "crosstalk" between the CAT6 cables connecting the two rooms to the 116. I know about cross-talk issues *within* a cable, but I haven't read/heard much about cross-talk *between* cables. Any thoughts on where to look and/or how to debug?
