[/FONT][FONT=arial]Hi everyone,
I wanted to ask if someone else experience network cutouts with newest firmware? My HW Version is V1, after I upgraded to Firmware 3.2.4_902111_170628_901 (EU) problems started.
After some days, connections break down and flapps between 1Gbit/s and 11 Mbit/s with short cuts, nothing helps just rebuild the network from scratch.
After that, it works again for a few days and problems begin again... Looks like some kind of buffer overflow or similar.
One Device is behind a Fritzbox with FritzOS 6.92, another one before a Cisco Switch, nothing special in the network. Is there any help?

Nothing changed in my environment only the firmware .. can I downgrade it? Or is there an inofficial beta firmware I could use with the EU devices?
Please advise, it isn't fun anymore :(

Kind regards,
Dennis
