Hi everyone, Infrastructure: I recently moved into a 3-stories house and I purchased 2 Wlan-Box 2 to extend the coverage of the WiFi from my Internet Box 2. I installed some smart switches from Allerco Robotics, also known as Shelly. Problem encountered: When monitoring my network from the web portal of the Internet Box, I noticed some unusual connections. I have mostly 10 devices, outside of the smart switches, that are connected to the Internet with a WiFi connection, and it is easy to spot them. This is not someone trying to hack my network as I have rule out the suspect or rather the suspects. The unusual connections are all linked to these smart switches. The Shelly connects to the network only on the 2.4 Ghz band. It appears usually with a name that is PC-XXX with a defined MAC address. Then, I noticed that a lot of other clients start to connect to the same access point, with a MAC address starting with 5E:BB:00:... I checked wether it was something linked to a specific manufacturer, but it doesn't. Under the IP address field, there is "Device doesn't need an IP address". With one Shelly connected to the Wlan-Box 2, there are about 23 to 25 connected device at the same time. It varies continuously when the Shelly is connected, new devices connecting with a name PC-XXX + 1 and older ones disconnecting from it. Network Topology Device List Strangely enough, these devices don't appear on the Home App. Moreover, when the Shellies are connected directly to the Internet Box, there is no such devices appearing. What I tried so far: I made some modifications to the Internet Box parameters without any luck. Static IP either on the router or the smart switch, WiFi 6 deactivation. I think I changed nearly all the settings without getting a different result. I reset every Wlan Box and Internet Box and also flashed older firmware without getting a different result. I tried to create a guest WiFi and move the Shellies on it and it seemed that there was no more ghost devices, but that is not really practicable, as I have to be one the same network to interact with them. I read that sometimes WiFi repeater give mixed results with IoT devices, so I used a long cable to plug the Wlan-Box as an access point, but there was no noticeable difference. I flashed an alternate firmware on the Shellies with native HomeKit support and in this case, there are no ghost devices. This is an open-source firmware and the capabilities, while promising, are still way behind the official firmware. This is definitely not an ideal solution for me. I flashed older firmware versions of the official firmware, without getting a different behaviour. It may be only a display glitch in the Internet Box web portal, as it does not appear with the Home App. Alternatively, this is maybe linked to the Wlan Box, because I cannot reproduce the problem with the Internet Box. I also contacted the manufacturer's support to see if the problem is on their side. Question: Has any of you experienced similar devices without IP adresses on the network ? Did you find a solution to get rid of them ? Any help would be appreciated
