See the solution below. A tech savvy poster in another thread did some digging into the wifi issues and came across the solution to our wifi problems that is currently working for at least three washers that I know of. Basically the washer, for whatever reason, will occasionally think that it's IP address is 192.168.1.80 on your wifi network. If your router automatically assigns IP addresses in a range of 192.168.1.XX, then you are most likely going to be fine and won't have this issue. If you are someone like me who owns a router like Eero, my devices were all being assigned IP addresses of 192.168.7.XX. This caused the washer to get confused when it ended up having two different IP addresses. You can read a more technical explanation here (not my blog): https://tylerrichey.com/posts/my-smart-washer-is-an-idiot/
To fix the problem, you need to be comfortable dealing with your wireless router's settings. There are only two steps though if you're comfortable diving into your settings:
**Don't make changes to your wireless router's settings unless you are comfortable troubleshooting any further issues or have access to someone that can help troubleshoot any issues that may pop up.
STEP 1: Change the DHCP server on your wireless router so that it is using IPs in the range of 192.168.1.XX. If your devices already have IP addresses starting with 192.168.1.XX, then you can skip this step. My settings for DHCP needed to be as follows:
STEP 2: Assign a static IP address for your washer as 192.168.1.80. Depending on your setup, it might be easy to find out which device on your network is the washer. If not, you'll need to find the MAC address of your washer, which may be printed on the back or might be found in the LG ThinQ app. Once your washer is assigned 192.168.1.80 it should not get confused anymore.
Thank you steinbch.
I too have an eero mesh and had been frustrated with the washer failing to stay connected to wifi. As a first step, I just tried to change my network’s address range and forced the washer to always get 192.168.1.80. This was still on the main network, though, and unfortunately it didn’t manage to stay connected for too long.
Next, I reverted my eero to completely autonomous DHCP mode and reset the washer to be on the guest network this time. It so happens that eero gave it a 192.168.7.x address to begin with, and later at some point a 192.168.11.x.
Regardless, ever since the washer has been placed on the isolated guest network, it has stayed connected consistently (a week or so and counting; hopefully I didn’t just jinx it).
Definitely seems like the WiFi driver on this machine is buggy and dies if/when it sees some kind of packets that are being passed around on my main network. Eero’s guest network is such that devices are unable to talk to other devices on the guest network and can only talk to the internet, so it drastically cuts down on the chance that an external trigger packet comes along to kill it. I’m just hoping I don’t run into the 192.168.1.80 bug because I cannot control the IP range of the guest network at all.
Anyway, so far so good (at least for me), so thanks again for the useful post. Wish LG engineering could be bothered to chase the actual problem, but they probably don’t have any incentive to proactively contact registered users to upgrade the firmware even if they come up with a fix!
Well, it's January 2021 and add me to the club with my washer WM3700HWA I bought in April 2020. Software version 3.32/clip_hna_v1.9.079_RT/SAA40284302.0000CAF9.0, SAA40864801.00007ED0.0.
Washer will show no wifi symbol on, so when I press and hold the button to turn it on, it responds with that generally unhelpful two beep error. It will work AFTER the first load though. This might explain why I sometimes don't get notifications for my first loads of washing being complete.
Maybe I just haven't noticed for a while since I don't use the wifi function as frequently as I thought I would.
Has there been an update on this yet?
I'll echo this as a correct solution and my thanks. My approach:
I had an old Apple Airport Extreme (APE) laying around. I set it up as a standalone wifi access point with ethernet access to the main network. Note that in APE I set it up for DHCP and NAT so that I could control the IP range (192.168.1.*) which is necessary for the solution as my main network has a different range. From there you can do a DHCP reservation to map the washer to the 192.168.1.80 address.
Ultimately though, this is ridiculous and definitely a disappointment from LG.
