This is taking place in several waves. **Information about the new firmware?** 1\. The firmware designation is: LG-RDK_11.10.26-2410.5. If you have this firmware, you have the new features. 2\. HTTPS-encrypted local UI & landing page (**\***) 3\. Adjustment of the third octet of the local IP range (previous example: 192.168.1.10, new example: 192.168.5.10) 4\. Improved interoperability with Sunrise TV Box, fewer connection interruptions 5\. Stability improvements (**\***) When you access the router interface, a security warning will be displayed before you log in. Click on ‘Continue’ in this warning. Additional warnings may be displayed, informing you that the page is not trustworthy. The reason for this is that a self-signed SSL certificate is implemented in the modem's firmware, but the browser or security software used cannot find this certificate in the usual place on the Internet due to the usual security checks. A permanent solution will be implemented in future firmware versions, which will make the display of this message unnecessary. Greetings Daniele

@"Daniele_Sunrise"#p301129 that might have big consequences, shifting the IP address where customers would have avoided 192.168.1.x address in my case, behind the Double-NAT setup I use 192.168.5.x, so this will surely bring down the internet. Honestly the full IP of Connect Box needs to be configurable, (like any typical ISP modem is) This will create allot of support calls to your hotline, you can measure the impact by checking data from the TR-69 updates and get an idea of the downstream subsets utilized

You may have misunderstood. They've just given an example of what you could do. After the firmware upgrade, everything is still 192.168.1.xxx but the third digit (the "1") is now changeable if you so wish. I was upgraded last night: [upl-image-preview uuid=e2c7130b-ccd5-4d9c-bb0c-c33b0075cb82 url=https://community.sunrise.ch/assets/files/2026-01-27/1769522507-971587-screenshot-2026-01-27-at-150055.png alt={TEXT?}]

This seems like a coincidence, but it's too much of one! Prior to the new firmware, I would have an occasional pixelated pictures on my live/cable TV channels. Also, the modem would have logs implying signal interference (channel changes etc.). Immediately after I got the new firmware, both problems stopped. If you have the Connect Box 3 HFC, and for some reason don't yet have the new firmware, make sure you leave the box on overnight and get it!

That's a great update, the HTTPS, however, the certificate seems to be wrong: [upl-image-preview uuid=16e36f9d-a74a-4864-9b4a-0b2b9efc2847 url=https://community.sunrise.ch/assets/files/2026-02-06/1770395209-295782-image.png alt={TEXT?}] [upl-image-preview uuid=1ec37edc-ed7d-46a9-b19b-1b5a0c4ad497 url=https://community.sunrise.ch/assets/files/2026-02-06/1770395221-54901-image.png alt={TEXT?}]

It's not so much "wrong", but it isn't passing browser tests. You need to manually add the certificate so that the browser allows access and stops complaining. I don't know why Sunrise (a) wanted to encrypt the modem admin pages anyway as they're only accessible from within the LAN, and (b) if they deemed it necessary didn't wait until they'd gotten a proper certificate organised. I'm sure support must be getting lots of calls from people wondering what's going on. If you look at Daniele's post at the top of this thread, read the * bit.

Thank you Daniele, The Local Subnet customization was long awaited. Finally it is here (but router not yet updated) Can you please allow custom DNS servers as well in the settings, to be able to specify secured DNS instead of "basic" Sunrise DNS ? Best regards

@"Daniele_Sunrise"#p301129 How will we know when this firmware is installed? Will it be automatically installed by Sunrise or do we need to reboot the router? Are there new settings or features inside the new firmware that will need our attention? Thanks.

For me, the firmware updated itself overnight and caused a router reboot around 3am (I think). You can check the firmware version by logging into the router, but note the new SSL and certificate issue mentioned under (*) in the first post. However, you don't actually need to do or check anything; the router just continues to work as before but with a newer firmware.

@"adrianlondon"#p304221 Thanks, Adrian. I logged into my router interface around 10 days ago but didn’t see any security warnings (per Daniele). I also didn’t know to check the firmware version as I was looking for something else and I just learned of this firmware update. Maybe I’m in a future wave of updates?? Do you recommend waiting a few weeks before checking again? I want to make sure my router is updated. Hopefully, there are some new security enhancements in this newest firmware update. Thanks so much!

If you logged in without using "https" and without getting a cert warning, then you most likely still have the old firmware. Log in, go to Admin / Info and check "Software version". If it doesn't match what it shows in (1) at the top, then you don't have the new firmware. Apart from the SSL thing (which I personally think is a waste of time 😁 ) Sunrise talks vaguely about performance improvements. They don't mention security at all. They do say one can now change LAN IP addresses from 192.168.1.xxx to 192.168.anything.xxx but I doubt many users care. I'm surprised your router hasn't been upgraded yet; do you leave it on overnight? Anyway, just check every few days for your own curiosity; there's no way to speed it up and imo it doesn't really matter anyway!

Rollout of new firmware for Connect Box 3 modems

Ant8e

Seems like my connect box is still on the old firmware.

Is there a way to upgrade manually?

Does the new firmware allows to configure static routes ?

adrianlondon

I’m surprised your firmware hasn’t been updated yet,

You definitely have the (not DSL) Connect Box 3 and don’t turn it off at night?

As for the changes … only what’s listed in Daniele’s opening post has changed.

Ant8e

adrianlondon

That’s what I have

It’s usually on 24/24

adrianlondon

Someone in the German language section also posted recently that they’ve not yet got the new firmware.

I think they also have the fibre CB3.

So … you just have to wait! There’s nothing much interesting in the new firmware anyway unless you’re desperate to change from 192.168.1.xxx to 192.168.<your_choice>.xxx

adrianlondon

Yes. I was hoping that I could split my home network into multiple networks. But I do not see it possible without even with the new firmware ☹️

hello Ant8e

If you want to use VLANs on your home-network, you’ll need a router and other network hardware supporting VLAN.

You can use DMZ to forward all incoming traffic to your own router.

Ant8e

Xydocq

Yes, I have one, that is currently setup as a transparent bridge. I would still prefer the option of routing at the IP level between multiple nets/VLAN

Xydocq

Ant8e

My home setup looks like this:

Connect Box 3 HFC 192.168.1.0/24 DMZ to 192.168.1.2
Zyxel USG Flex 200 WAN IP:192.168.1.2 Gateway: 192.168.1.1 Subnet:/24 DNS: 8.8.8.8 and 8.8.4.4
LAN1: 192.168.20.0/24 (Management, ALL access allowed, VPN allowed)
VLAN11: 10.10.1.0/24 (Family Computers, WAN access only)
VLAN21: 10.10.2.0/24 (TVs, WAN access only, bypass UTM)

Ant8e

Xydocq Nice setup! So it’s doing double NAT once at the Zyxel and a second time on the Connect Box, right ? No issues with that ?

Xydocq

Ant8e

I do have double NAT but it is no big issue. My connection is as fast as it can be and it is very stable.

I did some testing with Router Mode vs. Bridge Mode. No real difference, I also noticed my pings are faster then in Router Mode. Currently they are 12 to 14ms, in Bridge Mode they were 15 to 18ms.

Ant8e

Xydocq Thanks for sharing. Might move to this kind of config in the future
