FRITZ!WLAN Repeater DVB-C Service

Push service mails are not

The FRITZ!WLAN Repeater cannot send push service mails with connection and usage data.

One of the following error messages is displayed in the event log of the repeater:

  • "E-mail delivery failed: SMTP server reports [...]"
  • "E-mail delivery failed: TCP error"
  • "Sending of an e-mail message failed. Reason: authentication error."
  • "Sending of an e-mail message failed. Reason: TCP error."


  • The SMTP server entered in your repeater for your e-mail provider does not respond to the connection request sent by the repeater, for example due to incorrect account information or because your e-mail provider is experiencing technical difficulties.

Adjusting your Google account settings

Adjusting your Microsoft account settings

Adjusting your Apple account settings

3 Enabling POP3 download in your e-mail account

To retrieve your e-mails, you must use an e-mail account with a POP3 e-mail server, and POP3 download must be enabled with your e-mail provider:

  • Enable POP3 download in your e-mail account settings. Your e-mail provider can provide you with information on the procedure.
