FRITZ!WLAN Repeater 300E – Service

Push service mails cannot be sent

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.

1 Installing the latest FRITZ!OS for the FRITZ!WLAN Repeater

2 Adjusting the e-mail account settings

Many providers employ special security mechanisms to protect their e-mail accounts. They may also prevent push service mails from being sent:

Adjusting your Google account settings

Adjusting your Microsoft account settings

Adjusting your Apple account settings

  9. Enable the option "Send a test e-mail to the given sender to make sure that the account data were entered correctly."
