HI TP-Link, the oven (mountain house) is Siemens HN678G4S6/94 software version 66.4-2.11.6.13174, the other oven (sea house) is Siemens HN678G4S6/69 software verison 65.3-2.11.6.13174. Unfortunately I'm at the moment in my main house so I cannot ask my mountain neighbor the detail of his Bosh dishwasher but if you need I can do it next saturday. The oven are connected to the 2.4ghz of the MR600, to avoid issue I turned off the 5ghz. Yes the ARP table is under the path you described. The oven connection is never working I can see the oven in basic settings but only there in the Home Connect App I can't never see the oven when it is connected to the MR600 (also the oven is telling me the it is connected to the router but it can't connect to home connect server). The oven is not present in the ARP table and it appears only and for a while when I ping it from my laptop for the first time after the router restart). All other device are working correcly in the two house I have with MR600 - Samsung Smart TV, LG washing machine, Alexa device, smart plug in, Sonoff devices, laptop and mobile phone/tablets) Also the two ovens are working correcly if I connect them to standard adls router (and I firsly thoght it was an issue of aving a 4G devices) and now that my mountain neighbor installed a 4g router we did some test and we found out that the problem it is not related to 4g network but to the router (if I put his sim in my router the problemis the same and if i put my SIM in his router everiting works perfecly - connecting the oven to his router with my sim). So we did many test and we sow the issue in the ARP table and with the ping on the router network. If you can explain to me how I can download the system log I will send it to you next saturday when I'll go to my mountain house (please write me where I can send it). Many thanks Riccardo
