LG Washer keeps dropping wifi connection, solved!

Well I stand corrected. It seems that putting our washer onto a different network has fixed the dropout issues. I use ubiquiti, the quickest solution for me was to create a new hotspot and configure it to only allow internet access, so it sees nothing locally. The washer is brand new, F4V710STSE. The modem in is (as they call it) is clip_hna_v1.9.183_RT if that helps anyone. It's amazing that they are still releasing these to market in this broken state.

Thanks for the update. Definitely impressive that after so much time, LG is still using the buggy adaptors.

I've been dealing with this cluster-XXXX for ages. For the first year we had our new LG washer and dryer (models WM4000HBA & DLGX4001B respectively) had zero issues with the connectivity with the app. Then, it simply decided that no, it was not going to stay connected in any way for more than a few days. Tried an assortment of suggestions from here and elsewhere to no avail. Gave up for a year. Tried again this year - newest discovery, after going through the hoops of deleting and adding, having it work for a few days, it would simultaneously report both washer and dryer had lost their connection...at precisely noon whenever it happened. As in, within seconds of straight up noon. I run my own GPS-disciplined timeserver, and the network is synced to it, and the alert would come in no more than about eight seconds after noon. Why?

Why does any of this happen! it's an absurdity. I would set up washer and drying on a dedicated wifi extender which itself connected to the main wifi router's 'guest' network. Fail. Tried putting one device on that, and the other on the main wifi. Fail. Discovered that at some point after doing all that setup, it would at some point just switch both devices back onto the main wifi without any intervention. (no easy way to do a VLAN regrettably).

Next up, completely delete the LG app after deleting data/cache for it, and try again, because it must have cached the main wifi password within itself - no other way it could switch on its own.

The washer/dryer themselves work just fine, so no way i'm spending more than 2.5 grand to replace them just over this. Still, what an annoyance.

This is particularly peculiar since I do not think either the washer/dryer or the app retains old networks. (Even changing the SSID used by the appliances can be a frustrating endeavor.)

If you cannot create a separate VLAN, one workaround you can do is put the washer on a smart plug. Then enable the plug when you use the washer, and disable it afterwards. Unfortunately, that cannot be done with the dryer, which is 220V. I cannot even reach the outlet, so on occasion I switch it off at the circuit breaker.

Edit: It does appear that the LG app can store multiple SSIDs, but I’m not aware that it can change the network without the user manually doing that.

[bclaymiles]

Yeah, it's just more puzzlement from this bizarre ugly mess of hardware and software that LG threw together and put on 'tumble dry'... Bad joke.

[nuc4and20]

The best explanation for why they continue to sell this junk is that this junk sells. The few of us who care figure out how to make it work and the rest simply don’t care at all.  I have rather enjoyed figuring out the solution and then learning how to implement it and confirm it. I figure this knowledge will help with other vendor’s crap.

[bclaymiles]

This is particularly peculiar since I do not think either the washer/dryer or the app retains old networks. (Even changing the SSID used by the appliances can be a frustrating endeavor.)

I realized later that I have the same password on both the main wifi and the restricted guest network, so I guess if it thinks there's a better signal on the other wifi channel, it can just try to connect. So next step, assuming this pass goes to heck at noon on some random day, I'll change the guest net pw and try it all again. (I don't use the guest network for anything else - just this - so having the same pw isn't a security issue since it is a very strong pw)

Did you all see this?

Your washing machine could be sending 3.7 GB of data a day — LG washing machine owner disconnected his device from Wi-Fi after noticing excessive outgoing daily data traffic

[nuc4and20]

My isolated “WashDry” vlan shows 0 bps up/down data rates almost all the time.

Cumulative stats are also very low.

When my phone talks to the washer, I see a few hundred bytes of traffic.  I’d be investigating a(nother) bug in the washer WiFi card. We’ve been focusing on how that card drops connections but maybe some of them start screaming when they run out of memory.

Buffer overflow, no garbage collection, and other sloppy programming might be at fault.  

Have any of us seen behavior as mentioned?

[frankielc]

My LG F4DV910H2 also has a very low profile regarding data usage.

[rh37hd]

This information has been super helpful. I've had this issue for years. I set my washer to reserve 192.168.1.80, but when the overflow (or whatever the issue is) happens, I don't get a notification and the washer shows "Offline" until I manually power it back on. Afterwards, it does seem to connect right up to Wi-Fi again. Is that the expected and "best" behavior without a real fix?

Before this workaround, I would typically hold down the "Temp" button to perform the diagnostics (no need to hold a phone up), which seemed to reset the Wi-Fi stuff (without having the unplug the washer completely). That worked pretty good as well, but is still a bit of a pain.

[nuc4and20]

I think you could call it "expected behavior" (of a buggy device)

As long as the device is in a collision domain with several other devices, the MAC table is going to chew up memory until there is no free memory left. Unless the device is on a VLAN with very few devices it will continue to drop off the network.

My "WashDry" VLAN has two devices and has been stable for many months. I kinda knew the solution but I tried DHCP reservation, separate SSID (on same subnet), etc. before I tried a separate network on a spare wireless router that I had lying around. That worked and I finally decided to add another VLAN and SSID to my Ubiquiti , which turned out to be a lot easier than I had feared.

What ended up working for me is putting the washer on an access point that uses only 802.11 g/n.

My primary router is WiFi 6E with 2.4/5/6 GHz WPA3 enabled. My wireless printer required a legacy network, so I repurposed an old router in bridge mode and enabled only 802.11 g/n WPA2. It is on the same subnet as the rest of my network. I connected the LG to that 802.11 g/n network.

I don't know why this works, but it works for me. Perhaps the primary router is ignoring a lot of traffic coming from the access point. If I put the LG on the primary SSID with the rest of my clients, it will drop the connection before a single load of laundry is done.

It's kind of wild how much time so many of us have spent to work around this issue.

[nicholashead]

Yep, the thing that worked for me (and has been for years now, I commented earlier on this thread) - is putting the devices on their literal own 2.4 SSID, with "client device isolation" on just for extra safety. Has been solid.

[bclaymiles]

Another 'me too' here. Put the washer & dryer on their own separate wifi extender (old and sitting in a drawer previously), made the extender live on a 'guest' network on a separate private IP range, and bob's your uncle. I even have the washer on a 'smart plug' that disconnects power between 10:30pm and 6am. Why? Because the washer alone uses 2 watts when sitting idle, and the smartplug only draws about a quarter of a watt.

Yeah, I'm that guy.

However, this does demonstrate that the washer definitely has some small amount of non-volatile storage in it, otherwise it'd require complete reconfigure every day in order to restore the configuration. It's highly unlikely that they outfitted the internals with either a 'bios' battery or a supercapacitor to retain the settings.

[nuc4and20]

Before I figured out how to keep the washer on the network, I did the recommended unplug-plug-reconfigure routine a few times.

The plugging-in was always accompanied by an ugly SNAP and a spark and it occurred to me that electrical equipment doesn't like sudden applications of power.

On/off switches usually have some kind of protection for that. In spite of the reassuring words that were printed on the little "documentation" for my smart switches I am not sure the kasa EP10 can really handle the job.

I figure 2 watts would be cheaper than whatever is happening to the washer circuit boards. Nick

I purchased a LG washer dryer in 2022 - WT7400CV and DLE7400VE. I had a terrible time keeping that washer dryer connected to the internet. Last year (2023), LG downloaded updates to those appliances that brought them into compliance with "Matter" network standards. The internet connectivity standards have been solved. The LG ThinQ app has been rock solid. I have other "Matter" certified IOT devices, and they have all had perfect, never fail connectivity. I don't think it is complicated. "Matter" devices all have the ability to know if they have lost connectivity and have the ability to reconnect to a network with parameters that are permanently stored within the device when you set it up. "Matter" devices can recover from power failures for example.

11th January 2022 LG ThinQ App Adds Limited HomeKit Integration If you’re a user of smart LG devices and use the LG ThinQ app with them, there’s an update for the app that now adds limited HomeKit integration. This integration really is limited in a few ways, however. https://homekitnews.com/2022/01/11/lg-thinq-app-adds-limited-homekit-integration/

[frankielc]

The internet connectivity standards have been solved.

Hi @truerock2, thanks for sharing. Unfortunately, for most of us, this looks like something a level below it. As soon as the machine hits the overflow it's dead. It won't have difficulty connecting. It's just dead in the water. You have to do a full reset to bring it back up. Even disconnecting / connecting the machine to power will be pointless.

I am not sure the kasa EP10 can really handle the job

Hi @nuc4and20, when I read the above, I was really puzzled. I'm renting, it doesn't have central heating, all rooms have electric heaters connected to the standard plugs.

As I wanted a linear and constant temperature across the rooms, I've built a mesh of TP-Link HS110, ESP32 controller boards and bme280 thermometers. The ESP32 continuously read data from the bme280 thermometers, which are placed far away from the heater. They then send data to a home server that decides when to power on or off the HS110 that's connecting the heaters to the wall.

It's raw but has worked for 3 years now. As far as I could tell the largest heater can go up to 3000 watts/h and the plugs are rated at 16A which gives about 3500 watts/hour.

And then I drew on me that you must be on 110V and thus would need 32 amps and the plug would have to be bulkier.

[nuc4and20]

I guess I thought you were using the EP10 to power cycle a washer like my WM3600HWA. Heaters don't seem to be as power hungry. Nick -------- Original message --------From: frankielc @.> Date: 5/10/24 11:10 (GMT-08:00) To: wasteofserver/site-comments @.> Cc: Nick @.>, Mention @.> Subject: Re: [wasteofserver/site-comments] lg-washer-keeps-dropping-wifi-connection-solved/ (Issue #4)

This seems to work! Thank you!

I have a dialog going with LG and latest they said is this:

Hi Jeff, There have been issues in the past with IOT devices interfering with communications between the appliances and the router. Would you mind creating the new VLAN for just the washer to see if this resolves the issue?

I’m going to see if she has a new FW update that would fix this.

[nuc4and20]

Has LG been reading our discussion? 😉

Here's the software version information for my washer: What versions are other folks seeing?

@nuc4and20 no, I forwarded them this thread. I managed to find a contact who seems to actually be able to help. Apparently firmware is different for every washer model number too, so sharing that info may or may not help.

Here is what I have.

Washer: Modem clip_hna_v1.9.205_RT Firmware 1 SAA42462901.000058B7 Firmware 2 SAA42102301.00003A67

Dryer: Modem clip_hna_v1.9.205_RT Firmware 1 SAA38964435.0000574B Firmware 2 SAA38964313.0000FFDB

The issue completely resolved after putting the LG on an access point restricted to 802.11 g/n. It’s not on its own VLAN.
