Hi how 40mhz turbo enable in 2.4ghz

Iam installation 12 cap ac xl in location
Maximum speed 150mps
How i can get 300 mps
40mhz*2

AFAIK 40MHz is the widest you can go on 2.4GHz (20+20) ?

Without knowing your config nor the environment where you installed these devices in, nobody can answer why you are “only” seeing 150Mbps.

examples of questions:
Do you use capsman ? Local forwarding or central forwarding ?
How free of congestion are the frequencies being applied to those cap devices ?
Have you scanned the environment and chosen each frequency yourself or do you use auto (=not so good since you don’t know what it will take) ?
Or (shivers …) are all APs set to the same channel ?

We need more info. A lot more info.

Another underestimated and never considered question:

Can your device reach 300Mbps?


And if the technology is called “40MHz turbo” it’s time you took some refresher courses…

Iam used capsman
Frequency is 2437

My device reach 300
OK give me course refresh

The supported channel bonding is 20+20 as mentioned (and usually not recommended), so you’ll need to use the other band to get the speed you require on that device.
