The musical performance of Källa can be significantly improved by setting it to a fixed IP address, instead of the default setting which is DHCP (where the router assigns a network address to Källa).

Please follow the below steps, which are valid for a typical home network.

1. Using a web browser (Safari, Chrome, Firefox, Opera, etc.), enter the IP address of your router in the address bar at the top. The format is like the following example: If you don’t know the address, check the bottom of the router or google its name and ‘IP’.

2. Check what DHCP range your router has. This is the last number in the IP address, which the router assigns to every device that appears on your local network. If the range is for instance 100 to 199, you router will pick a number in that range and assign it to a device when it appears, like when you first switched on Källa. Now pick a number outside of this range and remember it. In this example you can pick 200. The example fixed IP address for Källa would then be

3. Now check which IP address the router has given Källa. This can often be found under the label ‘Devices’, or something similar. In the above example, your router might have given Källa the IP address

4. Enter Källa’s IP adress in the address bar of the web browser. You just need to edit the last number and then press return. The browser will now leave the router and connect to Källa. You should now see the web interface of Källa:

5. Choose Settings. Then select Manual. You should now see the manual IP configuration:

6. Under ‘IP address’, enter the IP address you picked in step 2. In this example, we chose 200 as it was outside the DHCP range of the router.

7. Enter the Netmask address:

8. Enter the router’s IP address in the two fields below ‘Default Gateway’ and ‘DNS’.

9. Click ‘Save’. You will now return to Källas main page. Källa will now prompt you to reboot it. Click ‘Reboot’.

10. When Källa has rebooted and plays the startup melody in your speakers, its web interface is now available at the fixed IP adress that you chose. In this example, it’s

11. Play music and enjoy the higher musical performance!

12. If you wish to access Källa’s web interface again, you need to enter its new (fixed) address in the address bar of your browser. If you wish to access it more easily on your iOS or iPadOS device, choose the Share button (box with an arrow pointing up) and scroll down to ‘Add to home screen’. Källa’s web interface will now appear like an app on your device.

Note: If you set Källa to an incorrect fixed IP address – one that your router doesn’t accept – then Källa will play a deep bass note in your speakers. Källa will then revert to DHCP.
