just needs to be set up correctly, so: there are several things to consider, speaking from experience, all options work
1. possibility - connect - log in - it works
2. possibility - connect - log in - internet - access data - internet provider sunrise - access type sunrise fibre l3 - now running
3rd possibility (if the way 1. & 2. does not work) - disconnect pc/laptop from the network - connect fritzbox to pc via lan - log in - system - backup - factory settings - load factory settings - disconnect fritzbox from pc - connect - do 1st or 2nd option - be happy
Hi PCforever... my "favourite topic"! I bought the Fritzbox 5590 for exactly this reason, but I was a bit unlucky with the support. But after 4 months I tried again with the Sunrise support... and now it finally works! :)
My requirements: - Sunrise glass connection via Swisscom, but this will probably be the case almost everywhere, as Swisscom is clearly ahead with the 'last mile' - I had to give the MAC address of the 5590 to support - You will receive a 6-digit activation code from Sunrise and then log on to the Swisscom activation page. - The activation can fail within the first 12 hours after changing the MAC address, which was also the case for me. - The morning after the MAC changeover, the registration worked
Oh, and one more thing: Yes, even a DECT Fritzfon can be registered afterwards via SIP with the help of Sunrise Support!
