You might have encountered this when establishing a brand-new clever house item: You have actually installed its buddy app, produced an account, plugged in the device, and you’re all prepared to go till you understand it will not link to your Wi-Fi. What’s occurring? You reboot the app, the phone, your router, and attempt all sort of other techniques to no get. The app declines to see or link to your network. In many cases, you’re not provided the thanks to a mistake message; in others, designers are kind enough to mention the concern: 2.4 GHz Wi-Fi.
The very first time this took place to me, I was establishing the $1400 Roborock S7 MaxV Ultra An eye-watering cost didn’t conserve this robotic vacuum from having an inexpensive Wi-Fi chip, and I was left questioning if it would ever deal with my dual-band router or I ‘d need to return it. (Spoiler: it works, however that needs workarounds that I’ll get to later on.)
I later on encountered the exact same concern with a number of Xiaomi clever house items (the Smart Standing Fan 2 and 360 Smart Security Video Camera), in addition to the Nanoleaf Canvas clever light panels, and Sensibo Aspects air screen Each time, I needed to duplicate the workaround to get them linked while mumbling my discontent. I likewise needed to do all of that once again when I updated my house network and altered my gain access to point. At that point, the air screen even stopped working to reset appropriately till I understood my error and changed to 2.4 GHz. The whining was even louder then.
See, I can comprehend choosing less expensive hardware options on a $40 electronic camera, however anything above $100 and more recent than 2015 ought to support dual-band Wi-Fi by default. Anything else is simply stingy. I anticipate compromises on an inexpensive electronic camera, I do not anticipate them on a state-of-the-art robotic vacuum or air quality screen.
So although this ought to not be an issue, it is. I have actually created a little guide to discuss the 2.4 GHz concern on clever house gadgets and some ideas and suggestions to prevent it prior to constructing your clever house or repair it if/when you encounter it.
Why some clever house gadgets just support 2.4 GHz Wi-Fi

The 2.4 GHz Wi-Fi band is older and more widespread than 5GHz. As an outcome, chips that entirely support it (i.e. no 5GHz, no dual-band) are less expensive and hence lower the costs of products for clever house gadget makers. That’s business description for why some clever house gadgets just support 2.4 GHz Wi-Fi.
However from a functionality point of view, 2.4 GHz likewise has some clear benefits. It has a longer variety and can more quickly permeate through walls and ceilings– 2 characteristics that are essential in the clever house. If you’re installing your security electronic camera outdoors, turning your lights upstairs, or running your robotic vacuum into spaces on the far side of your home, you require them to have a great signal in all those locations which’s where the 2.4 GHz spectrum shines.
And although 2.4 GHz Wi-Fi has a lower bandwidth than 5GHz, that does not matter much due to the fact that clever house gadgets do not require a consistent high-speed connection. The majority of them are merely sending out on/off and other easy commands, so they simply require trustworthy, low-bandwidth network gain access to throughout a bigger area.
So why is 2.4GHz-only assistance bothersome in the house?

Although 2.4 GHz sounds terrific on paper for clever house items, it ends up being a little bit of an obstacle when you toss our modern-day routers in the mix. Much of them, whether standalone systems or mesh systems, are at least dual-band. That implies they support both 2.4 GHz and 5GHz, not to discuss some brand-new ones that likewise consist of Wi-Fi 6E and 6GHz frequencies
Since 5GHz Wi-Fi is much faster, our phones advantage it and remain linked to it as long as they’re within reach. And therein lies the issue: If a wise house gadget can just link to 2.4 GHz Wi-Fi, its app throughout setup will just see the 5GHz band your phone is presently linked to, consider it incompatible, and decline to start a connection. Case in point, Roborock and Xiaomi grey out 5GHz networks on setup and will not let me link to them, although I understand among them is a dual-band network and supports 2.4 GHz.
The web has lots of individuals grumbling about this concern on whatever from their clever lights and security cams to their robotic vacuums and even photovoltaic panels. The concern is intensified when your router will not let you separate the 2.4 GHz band from the 5GHz one, which implies you can’t surpass the setup procedure in the gadget’s app. Picture tossing hundreds, if not countless dollars into an item just to understand it’s utilizing an older chip and can’t acknowledge your network.
How to prevent this concern?
The response is easy. Prior to purchasing any brand-new clever house item, you ought to examine its spec sheet and see the Wi-Fi information. Not every maker will consist of these, so a little bit of additional Googling or digging into assistance files may bring the response. If you see 802.11 b/g/n 2.4 GHz, the item will likely decline to link to your dual-band network. You can still purchase it and utilize it, as long as you make certain you can fix the concern.
Otherwise, any reference of 802.11 air conditioner or ax, 2.4 GHz and 5GHz, or dual-band Wi-Fi will indicate that the item is great linking to both networks and should not trigger any concerns.
How to establish 2.4 GHz clever house items on a dual-band network
There are a couple of workarounds to prevent this setup obstruction and get your clever house gadget on the 2.4 GHz band. A few of them are fiddly and undependable, others are not constantly possible.
Stroll even more away
If you can handle to move a couple of spaces far from your router, your phone may be out of the 5GHz variety and be required to change to 2.4 GHz. If you start setup then, your clever house gadget’s app will likely see no concern with the network and let you continue. This isn’t a guaranteed option due to the fact that your phone may hang onto the 5GHz connection till it’s entirely out of variety.
For a little while divide your router’s bands apart

Synology router Smart Link off
Depending upon your router, you may be able to force-split the 2 bands into different Wi-Fi networks. On my Synology WRX-560, the alternative is called Smart Link and I need to turn it off to get standalone 2.4 GHz and 5GHz networks. On other routers, search for choices like “different,” “split,” or “decouple.” Assistance files or a Google search are your pals on this journey. Some brand names go a various path too, with eero for instance letting you temporarily disable the 5GHz frequency rather of splitting the 2 bands.
Nevertheless, there’s one technique to bear in mind. Since I desire the split to be short-lived, I ensured the 2.4 GHz network has the exact same SSID name and password as the joint dual-band network I ‘d formerly establish. When I separate the networks, all my gadgets including my phone link to the 2.4 GHz band and I can establish my brand-new clever house gadget with no mistake in the app. Then, when I integrate the networks once again, all my gadgets reconnect to the router, selecting whichever band they choose, and yes, that consists of the brand-new 2.4GHz-only clever house device. Whatever simply returns to typical. You can see how the Sensibo Aspects are Roborock S7 MaxV are on the exact same network as my other gadgets, however they’re utilizing the 2.4 GHz band.

If this alternative is offered in your router’s settings, it is the most trustworthy one to utilize. You do not require to depend on luck or go through any headache-inducing procedures to perform it, though it might take a little bit of digging to discover it the very first time.
Establish a 2.4 GHz visitor network … or get imaginative
If your router will not let you separate the 2 networks, which is most likely a concern on some low-end ISP routers however can likewise happen on some excellent third-party routers too– cough, Google Nest Wifi and Nest Wifi Pro, cough– then you need to begin coloring outside the lines a bit.
Another alternative is to utilize another phone’s hotspot as a momentary middle-man due to the fact that some phone hotspots can be 2.4GHz-only. So established the hotspot with the exact same SSID name and password as your primary network (however understand that a few of your other gadgets around the house will change to it unless you turn them off for a while), link your phone to this hotspot, established your brand-new clever house gadget, then disable the hotspot.
If that does not work, there’s constantly the alternative of getting an old, single-band, 2.4GHz-only router and utilizing it to momentarily present your brand-new clever house gadget to the exact same network SSID and password. Otherwise, you can constantly attempt to return the item and conserve yourself all that headache.
It’s unfortunate to see that we remain in 2023– more than a years after the intro of 5GHz Wi-Fi– and some clever house gadgets still do not support it. And yes, there are numerous, numerous other concerns with the existing start of clever house gadgets, however not having the ability to link them to your network due to the fact that of a stingy item choice is, I attempt state, the greatest obstruction of all.
