IoT Network - Deco XE75 - Unstable
IoT Network - Deco XE75 - Unstable
TL;DR - I was hoping by enabling the IoT network I'd have stable connectivity as it's at 2.4Ghz. So far...not the case. Does anyone out there have same/similar experience and what have you, or can you suggest, be done ?
The attached image is my setup, a mix of ethernet from a switch off my router for work Laptops and the Deco's broadcasting 2.4Ghz & 5Ghz to all non IoT devices on "Internet" + all IoT devices on Internet_IoT. There are upwards of 70 devices attached to the network, most are running off the Deco's and many of those are IoT devices (TP-Link bulbs and switches, Google Home products, a Leviton switch and a Good Earth light fixture).
1. One of the Deco XE75's stopped functioning properly throttling bandwidth from an already bad 50 x 10 (my over the air Wireless) to 20 x 2 last week. I've now completely reset all the Deco's and rebuilt the network from scratch, not a trivial exercise.
2. Before and now again I'm having trouble with the Google Hub constantly dropping off the IoT network and reconnecting within 2-3min normally. Other devices appear to be stable but it's hard to tell as they don't have displays. The hub has been reset multiple times and is now off the IoT network where it's stable
3. The mobile app on Android is horribly slow to report device status and often reports Deco's offline for 2-3min when I know they're actually online
4. The browser portal is worse and missing many features, it stinks
PS: I's a big, old, long, farmhouse with brick and unknown substances in the walls that block signals, that's why I have 6 Deco's indoors, 3 backhauling by ethernet and the 6th, an M5 on ethernet in my garage. The network is in Access Point mode.

@MattPorter I haven't turned any IoT devices off when testing although most are off already and the rest, as you say, should be passive.
Amazon has the XE200's in pairs for $599 CAD + 13% tax and I'll need 4. Ouch !
Anyone wanna buy some XE75's...? I'll make you a deal !

@yo_adrian_eh I suggest trying one pair of XE200s at first. You can actually pair your XE75s with them - which would ideally minimise your issues. Use one of the XE200s as your router (add it to the existing network, then promote it to "Main"). If you can get wired backhaul to the other XE200, that could be a good solution.
In that scenario, the XE75s are relatively "dumb" devices, somewhat offsetting the lower CPU and RAM specs. Use them to expand the range of your wireless backhaul.
You may also find you need fewer XE200 units than XE75s, as the coverage and range are somewhat better.
Good luck!

I have noticed it is a bad firmware problem. This issue affects all 2.4G channel, Guest, Normal, or IOT. I have 4 Deco XE75, initially it was okay; after some firmware upgrades ... it started going down hill.
I have issues, connecting to 2.4Ghz WLAN be it, dedicated Guest, IOT, or normal wlan. 5Ghz and 6Ghz works just fine. Only the 2.4Ghz is a nightmare ... it is worse if you are using legacy 2.4Ghz smart home devices ... when they get disconnected reconnecting them is a pain, and getting to stay connected is another.
Changing any advance wireless setting like Beamforming (enabling or disabling), Fast Roaming (enabling or Disabling), OFDMA/MU-Mimo (enabling or disabling); renders the clients unable to connect if they previously connected using another combination. For example, if you added a device with your setting as - Fast Roaming - Off, Beamforming on, OFDMA/Mu-mimo on; and you changed that by turning off beamforming for example - those clients no longer is able to connect - and you will need to do a hard reset by deleting the device from your smart home app, and adding as new using your new configurations. And some devices are not so finicky; thus you are trouble-shooting - it be a nightmare. Because sometimes it works and sometimes it doesn't.
To illustrate a point - I use an iphone 15 pro max to connect to the IOT wlan, and sometimes I get internet connection, and sometimes it doesn't; and sometimes I stay connected for a few minutes and it hangs, and sometimes I can't even connect to it despite entering the correct password. Now at this point, I haven't even launch my smart home app to try to add devices. Imagine if I managed to add one, then next 20 minutes later I can no longer access the device from my home app, or voice assistants. TPlink really needs to fix this issues. Returning the device is not an option, I had them for 1 year now - these things are NOT cheap.

@Amberglow Yes, I had to revert the 1.2.5 firmware because the 2.4Ghz network basically, completely stopped working. All the same issues that have been discussed here.
Rolling back to 1.2.3 restored my network back to a working state. I'm not touching 1.2.5 ever again. We'll see what happens when they roll the next update, but for now the stability on my network is back to normal, which is to say good, with 1.2.3.
