Strange network behavior in mesh setup (2 x Carrier, 2 x Buddy 5)

[sstepane]

Hi,

I would like to ask if there's something I'm missing or something wrong with my network setup.

In short - quite simple setup. 1 x Carrier as a main controller (connected to ISP), 1 x Carrier and 2 x Buddy 5 set up as extenders.

Extenders - Carrier and 1 Buddy connected via ethernet, last Buddy connected via WiFi. Everything works fine. When I connect the last Buddy via ethernet whole network starts to "choke", packets lost, connection unstable, on mesh control page of the main controller devices start to timeout..

Can't figure out what's wrong.

Might be missing something. No fancy stuff installed or configured - everything straight forward as in manual.

Hi,

Seems that I found the issue. One of the switches was an "intermediate" switch (or smart switch, linksys 2008) and it was in default "STP" configuration thus interfering with mesh (over ethernet) setup. Setting it to "STP" mode for the port and giving it a lowest priority seems to resolve the issue. It was mentioned in one of the Keenetic notes.
