Info: upstream vectoring issue FRITZ!Box

Dear customers,

We would like to inform you about an issue we found with our FRITZ!Box 7360/7490 routers.

Problem: During the implementation of upstream vectoring, which allows upstream speeds up to 20Mbps, we noticed that during boot up the FRITZ!Box router synchronization falls back to 576kbps. This problem occurs only on vector profiles.

Solution: This problem is resolved in a newer firmware of the FRITZ!Box routers, but this version isn’t certified yet. We are working on an emergency certification process in cooperation with proximus.

Workaround: as the problem only occurs during the synchronization at boot up, just leave the router powered on, and after the first bad synchronization, pull out the DSL connection, wait a minute, and reseat it again. From then on the synchronization will act normally and upstream vectoring will be applied successfully.

If you have any questions left, please do not hesitate to contact us.

Best regards
The edpnet team
