I just wanted to give feedback on the admin password issue I see many people have posted about.
I wasted 3 hours and 4 calls to KPN, resetting - disconnecting - powering on and off - tinkering with 4 different browsers. The problem is clearly a major issue but KPN will not fix it and you will not get help from calling.
Download Firefox and re launch 192.168.2.254 was the only solution. I didn't need to adjust anything in Firefox, just install and the password change worked.
Save yourself time and just install Firefox.
