Internet isn’t working after activation

It’s the start date but you can’t get online. Start with the cause at the top, it’s the most common.

Updated 6 Nov 2026

Common causes

1The fibre box and router haven’t been restarted

Check

Have the fibre box and router been without power since activation?

What to do

Unplug the power to the fibre box and the router for at least 3 minutes, then start them again.

If it still doesn’t work, test with a computer connected by cable directly to the fibre box. If that works, the fault is in the router.

Test your connection directly at the fibre box
2The order isn’t approved or the invoice is unpaid

Check

Have you approved the order with BankID and paid the first invoice?

What to do

Approve the order with BankID and pay the invoice. We only activate once both are done.

Find and pay an invoice
3You end up on the city network’s website

Check

Does, for example, Zmarket’s or Zitius’s page show when you try to browse?

What to do

The old provider hasn’t released the connection, or activation isn’t finished. Restart the fibre box and the router. If that doesn’t help, email support.

The city network’s page shows instead of the internet
4The wrong apartment number in the order

Check

Does the apartment number in the order match the number on the fibre box label?

What to do

With the wrong number, another outlet is activated. Email support with the right apartment number.

5The router has a fixed IP address set

Check

Is the router’s WAN set to a fixed IP address?

What to do

Set the router to DHCP (get an address automatically). The broadband hands out the address itself.

Connect your router to the fibre box
6The fibre isn’t finished in the building

Check

Has the fibre been brought in and connected in the building?

What to do

Contact the city network, or email support and we’ll find out.

In Zitius’s and Telia’s networks, call 020-40 24 00, 09-16. Then contact us, and we’ll move the start date.

Good to know

  • Still not working? Email support your address and apartment number, how the fibre box lights look, and if you’ve tested with a cable directly in the fibre box.
