I have been a Sunrise Fibre internet subscriber for a number of years. Upon initial subscription, I opted to continue using my existing FritzBox 5490 router instead of the provided modem/router.
Recently, I received the Connect Box 3 Fiber from Sunrise. I’m wondering if it’s possible to maintain my current setup with the FritzBox 5490. My internet subscription doesn’t exceed 1 Gb/s, and I don’t see any significant advantages in switching to the new device. Moreover, changing routers would require reconfiguring all port forwards and other settings from scratch.
If I choose to keep using my FritzBox 5490:
Is this allowed by Sunrise?
Are there any steps I need to take to ensure uninterrupted service?
Are there any potential drawbacks or limitations I should be aware of?
I appreciate any insights or advice. Thanks all.
