It’s relevant in the sense that folks shouldn’t count on “smart” in these smart devices, Paul. But this post on isolation may explain your situation a bit more.

No offence was taken.

I gave a specific example, one that bit me (hard) when I experimented with brand new TP-Link Matter smartplugs — of Apple’s home automation software not working as expected, though the IoT devices themselves had been functioning as expected prior to being SSID segregated.

I called myself having read this article but saw nothing relevant that discussed this, even upon reread. My apologies if I offended.

Per the stuff you wrote, the advice is exactly what they should follow, Paul. Make sure you READ before leaving a comment.

Unless Apple reworks Home.app to merge devices from multiple SSIDs, the IoT devices that you actively interact with (e.g., smartplug for turning on/off light) would likely need to stay on a dual band SSID. Don’t expect to use Siri as a workaround either.

Not advocating for either SSID naming approach; just don’t spend the night migrating everything to a new broken-out SSID w/o realizing these ramifications. It’s a trade off for performance/security against ease-of-use.

Read the whole post, Chris. Seriously, that’s a *wise* thing to do before you make a statement like the one you just did.

Seriously? Pretty sure that’s what the local smith and livery owners were people about cars a century ago, too. Smart Home devices are here now, however new and limited they are. And they aren’t going away. The better prepared people are, the less negative impact these things will have on their lives. Telling people not to use them isn’t going to prepare anyone for anything.

I’ve also gone ahead and disabled MU-MIMO, OFDMA, and Beamforming. Will enable these one-by-one to find the culprit behind buggy AiMesh.

^^ This! For everyone reading this article, THIS is one of the keys to good WiFi performance and it cannot be understated. One too many times you have your WiFi 5/6 devices roam to 2.4Ghz and stay there forever until they reconnect (or roam to a different mesh node), resulting in horrible performance, usually due to the 2.4Ghz band being over-congested with neighbor APs, let’s not even begin to consider IoT devices that will exacerbate the mess…
IF your WiFi mesh/router allows it, separate bands on different SSIDs. If it doesn’t allow different SSIDs per band, upgrade to
something that will (Asus/Linksys come to mind). You’ll thank Dong later for this advice.

That will likely cause the band to run out of bandwidth fast. But hope it works.

Hi Dong, I spent the whole evening migrating all IOT’s to my guest networks (2 routers). Let’s see..
