5GHz Channel Settings

[Deleted member 28741]

Whats the best option for this switch?

Im using Wireless Mode = N + AC on 5ghz

Wireless General > Channel Bandwidth > 20/40/80? 20? 40? 80?

Only one AC device (phone). Rest of devices on 5ghz are N300+

What happens if I set it to 80Mhz? Will the non AC devices stop working?

Hi,

First a question to you: Any reason not testing it out yourself?

I would stay with the option to let the router and device figure out the best thing themselves...
Why you think to force something could be better?

With kind regards

You are right ... i should have tried it myself. I had jusy typed in 40 odd mac addresses and my brain wasnt working very well by the time i got to this setting.

I only asked because i couldnt understand the logic. I thought 11n was limited to 40mhz wide so why would it give me the option to select 80mhz after i had selected channel mode as n + ac...

80MHz spacing is mandatory for 802.11ac.
802.11n supports no more than 40MHz.

Though may confuse you, interface doesn't suggest you can choose 80MHz for 802.11n. It allows this while you have AC on.

You can force a certain channel spacing for AC, but this will make the difference into a lab. In real life you should allow the clients+router to choose the right spacing. By doing that it is more compatible with clients and it avoids some interference.
In a lab, where you control strictly the client and interferences, forcing a certain spacing will allow highest possible speed.

Short answer - leave it default; leave the router to decide.

Thanks very much for clarifying things for me. Much appreciated.
