Hello, thank you for your answer.
Here's mine:
All the devices are updated (some were already) to the latest FW.
It is not a connection problem, it is just really slow. So slow apparently that the ledprocessor can 't even ping to the server the check whether it is still online.
Signal strenght is stable and over average everywhere.
Everything worked fine until a few weeks ago. Problem started on all devices at the same time. Physically nothing happened to the devices, the weren't moved, the antennes weren't changed etc...
They all have the same signal strenght, one out of the 11 is still doing ok, the others are slow as ... It is almost impossible to teamview them.Is there a setting that can cause this 'slowlyness'? When a use my phone as hotspot next to a device and I connect my laptop to it it goes really fast, same provider.
I tried to send a testfile (around 20MB) with the pc that is connected to one of the routers using Wetransfer and it took me 4 (!) hours.
Thanks for the help
