Solving Internet problems with Swisscom

Troubleshooting on your Swisscom Internet connection

Connection problems, no Internet access

Key facts at a glance:

There are many possible reasons for having no Internet connection. There can be a connection problem between the Internet Box and the Internet, or a problem in your own network with the computer itself, a cable, or the WLAN.

If you can’t get onto the Internet with your computer, first check the status LED on the Internet Box.

What colour is the status LED on your Internet Box?

LED is red

LED is white

With the WLAN connection, please check the following:

  • Is your WLAN activated on the Internet Box?
  • Is your WLAN activated on the end device, and connected to the Internet Box?
  • Are you connected to the right WLAN network, and have you entered your WLAN password correctly?
  • Are you close enough the Internet Box, and not out of the WLAN range?
  • Restart the Internet Box and your end device.
  • If possible, try to connect your device with an Ethernet cable.



In all other cases:
