Hello, after receiving a new router from my internet provider (Sunrise, in Switzerland), almost all my Fibaro FGR-223 Roller Shutter modules (Z-wave) have stopped working: they appear in the app but no longer respond to open and close commands. Some were still working initially, but gradually they too stopped responding. So, I first looked for what was different about the new router: the biggest difference is that IPv6 addresses are assigned and I can’t disable them. My Homey therefore has an IPv6 address. I tried reinstalling the old router, but it still doesn’t work, which is strange. Needless to say, I’m very frustrated because all my blinds are only controlled via Homey… I can no longer open or close them… Does anyone have any ideas on how to fix this? Thanks! ---

Hi Philipe, Z-wave is unrelated to wifi. But Homey and IPv6 possibly aren’t friends yet and the Fibaro app might be influenced by the “not installed” Homey bug. Possibly the online “_is app X installed or not_” check mechanism has a hard time to reach Homey when IPv6 is enabled, at least that’s how I think it works. Make sure to update to the latest Homey firmware > [@Lights not working in Homey since last night (WiFi & Zigbee)](https://community.homey.app/t/lights-not-working-in-homey-since-last-night-wifi-zigbee/142337/6): > > Homey firmware is lower than v12.4.5, update firmware; > > ![Screenshot_20250829_014808_Chrome](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/c/4c42471b3b77ec4fb1f7e94e8d3be570d05f72ac.jpeg) > > (the description is not complete: _ **or when installed apps disappear** _ should be included). > > if it’s v12.4.5 or up: > disable IPv6 on on your router and see if this fixes the issues. > > If true: please do report to homey.app/support the IPv6 bug is _ **not** _ resolved ---

Thank you Peter. The fact is that my homey has a IP V4 and is up to date (v 12.8.2). I’m getting mad…. ---

Probably you looked into this, but just to be sure: you gave the new router the same SSID name (Wifi name) as the old router? This helps your existing hardware to easy access your Wifi / internal and external network. ---

You’re right, I changed the ssid name when installing the new router. I’ll try to go back to the previous one. Let’s hope… 🙂 But anyway I don’t understand why is the Homey so dependent from the router. Shouldn’t it run by itself ? ---

Well, restoring the old ssid didn’t make my homey work better. ---
