Now that I have added 2 more Unifi APs to fix up the 5GHZac dead spots (4 total in 200 SQM Home) I am now considering turning of 2.4GHZ

 

Has anyone done this? Had Issues with Visitors with old devices who can't connect to 5GHZac ?

Why do you want to turn it off?  Keep in mind a lot of "smart" devices for example run an ESP8266, or similar, need 2.4GHz.

yeah I would do that, but 99.99% of smart devices are on 2.4ghz only :(

I've tried doing that a few times now but failed & now its not worth the effort; there always ended up being 3-4 devices + the occasional visitor that didn't support 5GHz.

Yea IoT is the problem... Shelly's, Sonoff's, ESP devices, door lock, etc.

Thanks for the tips! I might leave it on for now, I have set the preferred band to 5GHZ so hopefully I wont have any devices fall back to 2.4 will just monitor so now

 

2.4 is sow crowded where I am!

I have turned it off, mostly to see what broke.  Nothing so far, figured if it wasn't being used may as well

Mostly Iot devices (scales, health monitors, cameras, smart speakers).

Also remember 2.4 GHz cover more than 5 GHz - may not be a big deal if you have good coverage with multiple APs.

Same issue as most of the other responders, too many older or IOT devices that are 2.4 only.

 

Modern Laptops, Fire Sticks, Echo Show etc are all 5GHz, but majority of devices are still 2.4.

Got the extra two Unifi's Now :) so will just see if the "Prefer 5GHZ" works as it should

2.4ghz here still does a good 200mbit real throughput so it's not too bad.

 

 

 

I keep 2.4ghz on for 3 reasons

 

1. Legacy devices that depend on it

 

2. Longer range for mesh until i eventually run a cable out to garage (Devices stay on 5ghz that way)

 

3. ESP8266's (on a seperate AP & VLAN)

 

 

 

i do however crank the power right down on my main 2.4ghz Radio's Simply because, there is no need for it and if there is, it's a close device or such.

2.4GHz here too, for coverage & the odd legacy device (e.g. printer).

I have it on with a different ssid, on 5GHz I have my richms-5 main vlan and a speakers one for the LG, amazon and google devices on 5GHz, and on 2.4 I have a iot and my richms lan for old crap. No point turning it off. If I am down at the end of the driveway I still have good 5GHz coverage so things hardly ever connect on the 2.4 even at high power. I used to have my iot on a seperate AP with a big amplifier to get full coverage of barely works from a single AP, but now I have it on a few of my unifi ac pros and it all works fine. Devices are never on the 5GHz unless I specifically choose to connect to it.

802.11n 2.4GHz here. No need to upgrade, and I'll soon be adding a Shelly device which only supports 802.11b/g/n, so not only will I be keeping 2.4GHz around for the foreseeable future, it would be considered an essential feature for any replacement hardware. When my old UniFi units are replaced, I may choose to run an independent AP for IoT devices where currently I have two SSIDs on the same hardware, but 2.4GHz is here to stay.

I've got the spectrum to myself, so I've got kilometres of range from 2.4GHz equipment around the property. Just wish they'd taken the 4 colour theorem into account when spectrum was initially assigned, would make the overlap so much cleaner. Using channel 13 almost gets you there but you can't rely on all devices seeing it.

Oh to live rural.... what are your broadband speeds though?
