Hi together,
we have a bad condition with MR 29.6.1 → MR 30.5 on AP MR36 ....
Let's try to describe:
We have 100 AP's, MR33, 36, 55 ...
In some classrooms we didn't have enough RJ-45 plug near the beamer/projector, so we had used network Splitter. (1)
This had works well with Firmware up to 29.6.1. After Upgrade to Firmware MR 30.5 all MR36 no longer has network connection to the MS Switches, if they are connected through a Network Splitter. They still are powered with PoE and could mesh, but they no longer accept the LAN Cable. On the Meraki Networkswitch the Accesspoint Port ist showen as only PoE, but not LAN connected
MR33 don't have this issue with MR 30.5
MR36 don't have this issue without splitter, or with the Firmware MR 29.6.x (or MR 28.x)
If i replace a "failed MR36" with a MR33, it work on the same cable with the Firmware 30.5.
I downgrade for now the firmware back to 29.6.1 and it's all "fine" - but we would like to use the a newer Firmware MR 30.x if the "bug" is fixed.
... Yes, RJ-45 Splitters aren't the greatest way to use a single Cat6e Port as two Cat 5e Ports.
Sadly we can't use a tiny network switch as we had two completly different VLAN Settings on this Cat5e Ports.
1) PS: probely i'll have to open a bug report
