Washing machine for mac11/22/2023 ![]() It’s been working fine for more than a week now. I start a DHCP server for the VLAN that will only give out one address: 192.168.1.80 3 I create a new VLAN for the 192.168.1.0/24 network and assign it to my stupidwasher SSIDs. My initial reaction is to firewall the washer’s ARP traffic and hard code the ARP table in the router, but after a deep breath I realize I can handle this with a bit more finesse. In my home, it’s never been on a network with a DHCP server that would’ve given out a 192.168.1.0/24 address. ![]() Previously, the washer was connected to a 10.0.0.0/24 address. You can see in the screenshots that it’s been using the address of 10.107.33.30 and working fine. The washer seems to arbitrarily decide to broadcast itself to the network as 192.168.1.80 2. I immediately check Wireshark to see what’s happened, and… I go about my day.Ī few hours later, I check the LG app and it’s disconnected again. It’s sending a “ping” via MQTT to an AWS IoT endpoint every ~60 seconds. However, I wanted this to run until the connection drops again and I needed a better way to analyze the data: How about we pipe the output directly to Wireshark? How about we capture some packets? Luckily, the UniFi APs I run make this easy to do via SSH: If I go through the steps and “change” the network to the same stupidwasher_2g, it will re-connect, but seems to die sometime in the next 2-4 hours. I go about my day and occasionally I’ll check the LG app to see if all is good. You can even read me claiming victory over on that thread. I step through the all too familiar steps to update the washer’s connection, and: it just works! No errors, no issues it connects I claim victory. I choose to split the frequencies into separate SSIDs. I craft a password that best expresses my current feelings towards LG. I create a new wireless network called stupidwasher. Except, no, I’m not updating all our other devices because of this stupid washer. Ok, so instead of having one SSID for 5ghz and 2.4ghz, I’ll split them. I head back to do further research, and then I remember that a cell phone hotspot is only using the 2.4ghz frequency. However, when I go to change the network afterward, I get the same errors. I get it connected to my wife’s phone’s hotspot and it updates the firmware and “reboots”. I continue to not have a lot of luck, but then someone suggests connecting the washer to a hotspot running on a separate cell phone, letting the firmware update, and then switching it to the proper network. Googling finds me a thread on the LG forums with some ideas. Same odd errors, same amount of forward progress. I try connecting it to my now “secure” SSID, the one it was connected too before, with no luck. I tried a few more times and then, before getting too annoyed, decided to switch and update the dryer’s connection first. It was giving odd errors about a “router out of range” or, perhaps, it suggested, I was using invalid characters in my SSID or password. It’s a fairly simple process to put the washer in the correct mode, and then step through the app to update the network. The update had to happen because I had just created a new VLAN specifically for all those “IoT” devices like washers, and lights, and plugs, so they can exist on their own network where they can only talk to themselves and the internet without having any visibility in to our “secure” network. The first time I set it up was not memorable. I assumed updating the wifi connection on our two month old LG WM3900HWA would be trivial. ![]() If that doesn’t work, I’d come back and read through this adventure + the comments to see if you’re able to find another solution that works for you. So, after some discourse in the comments on this post from other victims of the washer, if you’re looking for a tl dr of how to probably get it “working”: I think the best thing to try is placing the washer on your “guest” wifi network. As far as I can tell, LG still hasn’t fixed this issue.
