5ghz channel and 20/40/80mhz ?

[beachBOYken]

I've not had any issues with my AC86U dropping 5GHz WiFi, I currently use channel 100 at 80MHz.

Whatever the issue I have changed to channel 136 and put it on 40mhz, see how that goes.

What firmware do you use?

Latest Merlin, but it shouldn't really affect the WiFi as that's all closed source components.

Cheers, latest Merlin here as well.

Do you mind posting you wifi settings for 5ghz or do you leave everything on default?

Hey,
Doesn't sound too encouraging. Using channel 40 with 40mhz withw you are most likely doing eC so it could be worth trying channel 36 to see if it's a firmware bug which ideally will use Ce.

For testing you could try a 20mhz width, I know it's not as shiny as a 40 but you'll at least have double the spectral density in return and possibly a stable setup.

Since writing my initial response to you I've done further field testing and been lucky enough to learn from an industry insider that more or less write the book on WiFi implementation and the loudest comment I took from that was, stick with 20mhz. All my deployments now are 20mhz whether 5ghz or 2.

Interesting, I need to try a few thing's and its going to take time as the drops don't happen that often, I can go week's without a 5ghz drop sometimes.

I'm currently trying channel 100 with fixed 80mhz bandwidth, instead of the Auto 20/40/80 setting, the Auto setting I'm keeping clear of for now to see if it was the cause, likely not but you have to try things.

It's worth keeping in mind that not all devices can do 80mhz width so you may lose some completely. Auto will fold the width back to the lowest client.

That's what I thought but according to RMerlin who creates custom firmware for Asus routers, he stated this a while back.

"Anyway, 80 MHz is backward compatible with 40 and 20, I never understood the point in listing a specific 20/40/80 setting."

So basically the Auto 20/40/80 setting is not needed, some routers don't even list the auto option.
