New hardware that is not free cannot be a solution and I tried disabling Internet-Booster, it didn't help.

Various connected devices are constantly disappearing from the local network. Will this be fixed with the IB2 firmware update?

Hello @"Lar4ik"#230053 Are you still encountering issues with your installation? In case of the answer is yes, feel free to contact our technical assistance [https://bit.ly/3pFvCMe](https://bit.ly/3pFvCMe)

In the initial post you suspected an issue related to the booster. Now this sounds like you're also facing disconnects and drops even if the booster is not connected or powered off. First you should check if you really need the booster. I have seen customers which have the booster still connected even after a network upgrade to g.fast where the booster is not needed any more. If you still face issues without the booster even being connected you might try a couple of things: * Check your local network for any rogue access points. Sometimes old WLAN devices or even Routers are still used (or re-purposed as switches) and people forget to switch off those devices, causing WLAN clients to randomly connect to those devices getting wrong or duplicate IPs or even IP conflicts etc. Make sure to create an inventory of all your network devices. Use a mobile app like "wifi analyzer" to detect all access points and assure you only run the ones you need (internet box + eventually connected WLAN boxes) * Reset your internet box to default settings and restore settings or re-build settings * Disable band steering in your internet box WLAN advanced settings to try if some devices potentially do not like it * Try selecting another WiFi channel in internet box settings (usually this is not required as the box selects the best channel on restart)

This problem appeared after install Internet-booster. My speed without booster is 30 mbps and with booster 50 mbps, but due to problems in the local network, I will have to abandon the Internet-booster and send it back to Swisscom, very sad...

I wouldn't give up on using the booster. Even though your 30Mbps without booster aren't a totally disastrous value. Actually most users won't notice much difference in day-by-day use (meaning, non-speedtest use-case). Also still I am confused as you stated that you tried disabling the booster and it DID NOT HELP. So what makes you believe the booster is causing the issue? How does your topology look like? Is the booster connected to power and connected to the IB2 using a high-quality (shielded) Ethernet cable? Also you might want to assure your IB2 is running the latest [firmware](https://www.swisscom.ch/de/privatkunden/hilfe/internet/firmware-aktualisieren-internet-box.html#tab=internetbox). On your IB2 in the WiFi settings you might want to try disabling band steering and potentially also configuring another WiFi channel (try channels 1, 6 or 11 on 2.4GHz). Potentially disabling 5GHz WiFi entirely for testing might help identifying some issues with some devices. Also updating the WiFi drivers (especially if you have a laptop with crappy Intel WiFi drivers) might help increasing stability. WiFi connection issues can have many reasons including unexpected ones like defective power supplies or microwave ovens. Having a defective device radiating with 1W in 2.4Ghz area easily causes WiFi networks with max 0.1W to pass out. That's why I recommend to change channels first. You might also try to switch of or unplug devices for a day or two to find if one of them eventually causing radio noise and WiFi problems. Sometimes even physical distance to other devices will make a big difference.

When a device disappears from the local network, it only has access to the Internet and does not ping on the local network. For example, I cannot send youtube video to smart TV, because the TV is no longer recognized on the local network. I think this is the case in the special IB2 firmware for Internet-booster. Thats why disabling the booster does not give anything.

As of my knowledge there is no special firmware for IB2 when you have a booster. I used to own a booster too and it was never deployed with a special firmware. And how do you know that the IB2 disappears from the local network but still has internet access if you don't have access to it? By looking at the DSL light on the front as it stays solid white? You also say "no longer recognized on the local network". But it's not clear what you mean by that. The TV might not be able to connect to internet service or it reports the network link (cable) being unplugged/down? It is also possible that another device on your network is causing your issues. Do you have any other devices connected like different Routers, WLAN devices/routers, Powerline bridges etc? Are you sure you plugged everything properly and creating NO LOOP? I did actually visit a user once who reported that after certain amount of time his network is dead and only rebooting the IB resolves it for a while. It turned out the user plugged his compute into the IB and since he had a leftover cable he plugged port 2 and 3 with a loop cable. This surprisingly worked unless there was a Multicast/Broadcast packet sent in the network (e.g. from TV) which made the switch-loop cause the packet to loop and fully load the IB2 LAN side. As a result the box appeared "dead" and did not even respond to ICMP Ping any more. Can you draw a network diagram including all your devices you have connected? e.g. ``` [IB2] |- Ethernet -> [Ethernet Switch xy] --> [PC2] | \----- [PC2] |- Ethernet -> [TV] |- Ethernet -> [Swisscom TV box] |- Ethernet -> [Booster] ``` It might also be handy to upload pictures here showing all cables and devices and where they are connected - e.g. pictures from the back of your IB2 with all cables connected showing where those cables are going to (which devices, Ports, Bridges, Access-Points...) Make absolutely sure you do not create a loop. Networks are organized in Star-Topology. A switch or Router (4-Port Switch built-in into your IB2) is always connected to an end device like a PC, Laptop, TV-Box or TV. It might also be connected to another Switch. where more devices are connected. But NEVER EVER connect port x to port y on the same switch with a cable. Or connect two cables to the same switch like IB2 port 1 ---> Switch Port 1 IB2 port 2 ---> Switch Port 2 As this creates a loop and the data will flow on in this loop and fully load the network: IB port 1 --> Switch Port 1 --> Switch port 2 --> IB port 2 --> IB port 1... And yes, for the professionals here: I know about STP but the average home user doest not. EDIT: And as I write this I remember the IB2 supports STP. So what you can try too is to enable STP (Spanning Tree Protocol) on your IB2: * Log on to your IB2 web interface at [http://192.168.1.1/](http://192.168.1.1/) * Go to Network -> Settings and enable Spanning Tree Protocol (STP) at the bottom of the page This might help to resolve the problem in case you created a loop. It does not fix the problem but if it helps you will have to find the cabling issue in your network.

This problem did not exist before installing the booster. My smart TV has internet access but not response in local network, I can easily check this by ping the local IP of the TV. Only reboot IB2 helps. And this problem is not only with TV, but also with other devices in the house, and it only appeared after installing the booster. About special firmware I mean IB2 has special firmware or activated booster mode, you can see IB2 displays booster status and also does not have direct public IP, whether the booster is enabled or not.
