FRITZ!Box CONEXION-INTERNET-CORTADA on DSL router: brief drops
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
If your FRITZ!Box event log shows the internet connection was cleared and re-established shortly afterwards, FRITZ! puts it down to your provider's exchange. Turn on the option to maintain the connection permanently.
Safety first
Stop and check this first
- Do not change the user name, password or connection type in the account information: only use the details your provider gave you.
- FRITZ! says this pattern is not a FRITZ!Box fault: swapping the router does not usually fix a drop caused by the exchange.
Safe checks you can perform
- Read the exact event log message
- Enable Maintain permanently
- Check whether your devices notice it
- Tell your provider if it keeps happening
Leave these tasks to a qualified professional

What they doIf the drops repeat with the permanent connection enabled, the provider's technician checks the exchange and the session monitoring on your line.
They must show youthe drops recorded on their side at the same times as in your event log.
In writingthe ticket number, the cause found and the fix date.
Ask FRITZ! support
What they doIf the provider rules out their network, FRITZ! support can review the event log and the configuration of your FRITZ!Box.
They must show youwhich event log lines they analysed and how they read them.
In writingthe case number and the diagnosis.

What it means
FRITZ! describes, for DSL models such as the 7530, an internet (PPP) session that is cleared now and then and comes back on its own shortly after. The event log shows messages such as Internet connection cleared or PPPoE error: Timeout, Timeout during PPP negotiation. According to FRITZ!, the provider's exchange clears the PPP session or stops answering the LCP monitoring echoes, and it is not a fault of the FRITZ!Box. Neither the message nor the lights alone prove the router is faulty.
