Hello All,

I faced today very odd issue. I got brand new Xperia V12 modem today, for a fiber. I connected it, logged in, and was asked to change admin password. Which I have done, Then I configured WiFi and SuperWiFi point and at the end connect to WAN from Fiber. all was working pretty nice, but I wanted to check something later on and I tried to login to the xperia modem and it was just telling me that I am putting wron password. I checked on few devices and few browsers, nothing. I set factory settings and this also did not helped. Finally I got an idea to disconnect WAN cable and… voila, I was able to log in with an old password. So being logged in I connect WAN cable and… it kicked me out! I tried to login back but it told me wrong login information. My question is what is happening? Do any of you know the solution/had the same issue? 
and next thing is that KPN Thuis app doesnt see my modem when connected to home WiFi...is this somehow connected? 

Try Firefox, its a known bug unfortunately.

Well, I tried Firefox, Brave, Safari and Chrome on MacBook. Tried Edge and Chrome on Windows PC. Tried Safari and Chrome on iPhone. Tried Edge, Safari and Firefox on Windows Tablet. Everywhere effect is the same. Issue is not on my side. 
If this Is known bug,  then only thing left is waiting for KPN fix it?  I did not have this issue on copper with Fritz.Box. Now Having fiber and Xperia box v12… Other solution is to buy some devices by myslef and pack all Xperia stuff back to box and waiting till the end of contract?

 


There will be an update, but this is released in stages, this project is already running for two years so don't get your hopes to high. Can you just reconnect your Fritzbox or did you send that one back ? 


I still have it, but I will send It back, because I wand to have WiFi 6, which Fritz box is lacking. On the other hand, I can buy for example Xiaomi Mesh System AX6000 for 100 Eur and this I think also be a good solution.  Just watching now for any alternatives

 


Laso, I am not changing much after proper setup is done.  so for the time being it can stay like that. And if I would need to change something I just disconnect WAN cable. This is not like a critical issue, it's just an inconvenience,  I was more curious what is happening, why and if there is a fix for that. 
I don't understand the, if there is an update for that, why release it in stages 😃 Just let people download and update :D


Solution for password issues

 

1. Ensure that the WAN is connected.

2. Reset the modem and wait until it has fully started up.

3. Connect to the Wi-Fi or via a cable to the Box12 modem.

4. Open a browser (such as Chrome) and go to the following address: https://192.168.2.254 (important!)

5. You may see a message stating that the connection is not secure. You can accept this to proceed.

6. Enter the password to log in.

 

After these steps, the password should be working.

This was tested today already with a technician on the phone. Not working.
