The detailed investigation is expected to be completed within the next two to three weeks. We consider that there is a problem here with active packet and hardware acceleration. It is intended that packet and hardware acceleration remain active and re-enabled upon reboot of the operating system / hardware. Occasionally, customers have reported this error.Īt the first sighting of the data of other customers, we were unfortunately unable to determine the cause of the error that occurred in you. The firmware update to FRITZ! OS 7 may cause connectivity problems with NAS systems connected to the FRITZ! Box. Thank you for your request to AVM Support. Today I’ve got answer from AVM concerning this connection-problem. Because without you I would not have found the solution! Therefore, I sincerely award you the “Hero of the Day” certificate. Then I gave up.īut the internet knows everything. I spent about 4 hours with troubleshooting. And unfortunately, tonight, I also did a firmware update of my main POE switch. The Roon Rock was not affected by the connection problem.Īctually, I think that I have more than good network knowledge. Likewise I do not only have a Windows Roon server but also a Roon Rock. This is all the more amazing because in the 7490 this package acceleration is also activated and this does not seem to cause any disturbance. If I went with the iPad or the tablet near the 7490/7390, everything worked without problems. The amazing thing was that there was only a connection problem when I got the WLan from the 6490 Cable. All IP addresses and the WLan are managed by the 6490 (identical WLan, SSID & PW in the house). The 6490 Cabel is the master router, the 7490, 73 boxes are connected via LAN as IP clients. My network is not quite trivial, I have 4 Fritz boxes distributed in the house. Neither with the iPad Air nor with the Android Tablet I was able to connect to the Roon Core, things behaved exactly as described by Martin Kögel.

Tonight I was caught cold, since my FritzBox 6490 Cable has performed the firmware update to Fritz-OS 7.0. It will be useful info to have for any other users experiencing the same issue as you
