Dude33 Old/new IB3 doesn’t matter. The hardware is the same, so it makes no difference. Replacing routers is simply pointless in 99% of cases. And it doesn’t matter whether it’s copper or glass. Makes no difference either.

This problem seems to be caused by something in your home network. You can no longer access the start page of the router menu with any device? Are you using 192.168.1.1? That’s a strange problem, which I’ve only seen very rarely so far. It was usually enough to call up the page again in the browser.

Dude33 Why don’t you try a downgrade via the hotline 0800 800 800.

Have you ever tried to access the Web GUI with a PC connected directly to the IB3 with a LAN cable?
If that doesn’t work either, what exactly is the error message?

5018 No, I’m using 192.168.180.1 the settings are all exactly the same as before… I have saved them in the Swisscom portal as a backup so that I can restore them as soon as the new firmware has an upgrade and I might run into a problem. That didn’t help either. I will probably have to call support again for a new box because the old firmware is still not available to install it again.

Dude33 The old FW will also no longer be available. Then try 192.168.1.1 Your special configuration may have been overwritten.

5018 Thanks for the input, but it can’t be because the special config sometimes works but is usually no longer accessible - all other devices work.

Dude33

There is something wrong with your config in the new firmware.

What happens if you just leave it on factory settings?

Do you have a special VPN configuration, this could be a possible cause.

Sometimes it is better with a completely new version.

Re-enter and save the port rules.

On my IP, only the 3rd digit of the IP address has changed.

192.168.11.1…..

I have no problems with this.

I have several port forwardings on it.

I have also activated Wireguard there, which is available with version R15.

I have thrown the old VPN overboard.

A new router won’t do you any good either, because it will get the update sooner or later.

The fact that you are not using 192.168.1.1 is new information. There may be an error with the change to R15 (where the basic operating system from Broadcom has been updated to a newer version). I’ll ask the router team.

5018 What about your findings with the router team?

5018 by chance I got a work around, after reseting the IB3 I installed the last running backup config from my Swisscom backup mechanism and disconnectd all Lan connections before that and connected only by WLAN, still the UI did not responde properly by producing strange error messages (see attachements) but after refreshing the page many times the Login page at some point will be displayed and stressing on just some times. If Swisscom wants to know more about the behavior they can call me and I send an invoice for my work on it. I stopp here, I am not a Swisscom employee
