Wifi and zigbee not so bright question

I use both 2.4 and 5 ghz wifi...newer stuff on 5 and some older cameras and the 2.4. I also have 2 2.4/5ghz repeaters. My question... If zigbee uses the same freqs do the repeaters also repeat the zigbee stuff. I can change my wifi channels as needed but does HE alow me to change the zigbee channels? can put wifi on lower channels and zig on higher if possible to avoid interference

Just fyi I am an extra class Ham(wa4bfe) and a retired network engineer (over 20 yrs). so I really have way to much to think about sometimes. and being retired twice (Air force and civilian IT) way too much time on my hands

I know I have read way too much over the last week and now my head is overflowing with WTF ideas.

No I'd think not - the repeaters just clone and rebroadcast the same SSID and channel as the router they're linked to, whereas Zigbee is on a different channel. I was looking for a mesh WiFi setup yesterday after having a few issues with my current router. I noticed that the TP Link model I was looking at (one of the newer Deco models) did in fact link the WiFi, Bluetooth and Zigbee between each access point. I thought that might be helpful to improve a Zigbee mesh where there aren't a great deal of nodes (I have 50 odd Z-Wave devices and just 1 Zigbee!)

Within the 2.4 GHz spectrum, WiFi and zigbee use overlapping frequency spectrums, but one doesn't repeat for the other.

WiFi, being a much stronger signal can drown out or interfere with zigbee, and therefore it is advisable to do what you propose below:

This is a good idea. Just be aware that WiFi and zigbee channel numbers are not in the same number series, i.e. WiFi Channel 11 != Zigbee Channel 11. The chart below from metageek might be helpful in selecting WiFi and zigbee channels that are distant from each other.

FWIW, my WiFi mesh uses channels 1 and 6, with a 20 MHz channel width.

I have two zigbee meshes - one on zigbee channel 15 and the other on zigbee channel 25. Everything has worked well for 2+ years.

This detailed article on metageek might be helpful.

Only if TP-Link permitted the zigbee radio to be configured as a zigbee router/repeater that can join a zigbee network setup by a different zigbee coordinator (i.e. Hubitat).

It appears that the TP Link Deco M9 Plus is a Zigbee hub (whose signal can't be turned off, and is compatible only with TP Link devices). So it's similar to Zigbee capable Amazon Echo devices in that it will have picked its own Zigbee channel which you cannot disable (which may conflict with HE's channel). At least that's what I gather from this: https://community.tp-link.com/en/home/forum/topic/264068

That’s not good :thinking:. I was considering the newer TP Link Deco 60’s over the cheaper 55’s. The main difference between the models is that the 60’s have Zigbee and one less Ethernet port than the 55’s.

Reading the TP Link forums, their kit isn’t getting much praise. I might have to go back to my original plan of a Unify setup (expensive and probably overkill for what I need)

That didn’t stop me :grin:.

Yes, connect to the hub and select Settings on the left menu, then Zigbee Details. At the top of the page you can select desired Zigbee channel. Be sure to save the chanche by clicking "Change Channel" button.

Between Unifi and the deco 60s, I would take the Unifi.

You won't use the ZigBee radio on the TP-Link for anything.
The configurability is far far less than what the Unifi platform will allow.

I've been looking a the Dream Machine All in One. I'd then plan to add an additional UniFi Lite Access Point upstairs. The only thing putting me off is that the Dream Machine All in One isn't WiFi 6, it's 802.11 AC so feels out of date to be buying new now. I'd perhaps have to price it up as separate elements to keep everything WiFi 6.

How many wifi 6 devices do you have? We have none. And even if we did, do we need the speed they provide? Nope.

By the time we have enough devices to even use wifi 6, they'll be on wifi 7, making the cost premium for 6 devices nothing.

Get what works for you today. There will always be something newer coming.

I have a set of deco 60s that I never deployed. I thought they would permit features our eeros didn't. Nope.

Point taken - 2 I think - my M1 MacBook Pro and my iPhone 12 Pro

Agreed - it's just I always try to get the most up to date tech at the time for that very reason.

I actually don't have a lot of WiFi devices on my home network. My existing R7000 router links to a couple of switches and probably most of my devices are hard wired to those. I just like the idea of having a wireless network and router that's robust and I want seamless WiFi handoff between access points. The Wifi issues I've had have been affecting my 4 wall mounted Fire HD tablet dashboards.

WiFi 6 excells when you have lots of devices. "old" AC works pretty well for sub 50 devices, depending on bandwidth needs.

AP handoff/roaming is 95% up to the device. The AP has to support the roaming standards, but actually performing the handoff is up to the device. Some handle it better than others (some completely suck at it).
