Silly question, is it ok to run both 2.4 GHz and 5 GHz on the same SSID?
I am doing that now on multiple networks without any problems.

It is possible to do it, and many people do it, but its not always the best way to set up a home wifi network. Devices that come and go from the network (phones, laptops, etc) will mostly end up on the 2.4 GHz band because that's what will come into range first. IMHO, its better to set up separate SSIDs for 2.4 GHz and 5 GHz, and then use the network preferences on your computer to preferentially connect to the 5 GHz network. Unfortunately, Android does not allow setting preferred wifi networks, so I just exclude the 2.4 GHz network from my phones.

For Smart Connect to work surely both id's need to be the same. I've not switched smart connect on yet was waiting until i'm happy mesh is stable before throwing something else into the mix.

It is absolutely okay to use the same SSID for both bands, in fact some mesh systems like Orbi won't even let you specify a different SSID. Aimesh does let you, one of the reasons I much prefer it over other systems. If you're router supports Smart Connect I recommend giving it a try. I've been using it with the default settings and have not once ended up on the 2.4 Ghz band in my home for devices that support 5 Ghz. With my old router that didn't support Smart Connect I would frequently end up on the 2.4 band even when I was in range to receive a 5 Ghz signal and my speeds were crap so I did what others indicated and setup separate SSIDs so I could force my devices to the band I wanted. So in the end I think it depends on your needs and capabilities of your router.

I think your last sentence captures the key points. With my dual router setup, there is no place in my home or yard where 2.4 GHz provides faster wireless speeds than 5 GHz (2.4 GHz RSSI can be and often is better but not speed), so I only use 2.4 GHz now for my wireless cameras.

Is anyone getting weird issues, where it looks like the stronger AP just dropped you (almost as if its radio is going through a reboot) and you are in dead air for a minute or so? My cell phone data usage went way up, since these drops kept happening.
My 3 x RT-AC68U got almost unusable, and I had to reboot the main router and the nodes after a couple of days of use. I'm not sure if that might have been due to extensive use of IPTV or what, but it was running into issues with the DHCP server (My android phone telling me that the network was full). Even after a total wipe/factory restore it was doing that. Finally, I've plugged in a different router, and changed the whole AUS setup to AP AiMesh. Now it's finally stable.
This was on the same SSID for 2.4 and 5 GHz, and pretty much on default setup.

Depends.. :) Around my appartment are 20+ active networks on 2.4GHz, but only two on 5GHz (108 and 161 channels). Having seperate SSIDs means I can "force" my devices to stay on 5GHz (channel 36, 80MHz width), and only few legacy ones are given passwords for 2.4GHz band.

This gives me better network stability.

My GUI showing firmware update available for AC88U running 384_20308 , not in a position to update at the moment , product webpages not updated for new version yet either.... wonder whats fixed/added ?

Most likely KRACK vulnerabilities are solved.

In another thread I read that the servers are being synchronized at the moment, so new firmware will become available within 24 hours.

Cool thanks , can't update for a day or so anyway, but think will switch on smart connect when i update as mesh seems pretty stable

Is there anyone experiencing issue while trying to reach AiMesh fireware downloading page? Each time I clicked the firmware downloading link, e.g. https://www.asus.com/Networking/RTAC68U/HelpDesk_BIOS/
it always be redirected to
https://www.asus.com/us/Networking/RTAC68U/
no matter what kind of browsers I was using. This started to happen after I upgraded my two AC68U routers to AiMesh.

Looks like you left off the /us in that URL.

Try this:

Has anyone been able to get email notifications to work from the Aiprotection section? I have hits in the 2 way intrusion detection but never receive any emails.

Just wanted to post on this thread as it is most current:

Is it possible to disable 2.4Ghz?

2.4Ghz is way too congested in my area, and I want to be courteous to my neighbors and use 5Ghz only. When I set up AiMesh, I can turn off 2.4Ghz antenna on the ROUTER (the 2.4Ghz LED on the ROUTER turns off), but the 2.4Ghz light does not turn off on the NODE. I can also connect to the 2.4GHz SSID on my phone.

Currently, the main can't disabled wifi in Node.

I guess this is a similar problem where you cannot configure some things in the node directly.

Is there a way to reboot the aimesh nodes from any UI, either web or iOS? Also, does anyone else have this problem where when they reboot only the main aimesh router they get slow speeds on the aimesh node until the aimesh node has been rebooted at which point full speeds are reestablished?

I just noticed the other day that the mesh seems to be showing up as individual clients on my client list, one for each wifi band, but under the same IP address. It didn't do this before, I haven't updated to the new firmware that was just updated, and I didn't change any settings. It didn't do this when I first set up the mesh, but for some reason it just started doing it. Is anyone else seeing this? Screenshots are attached, one from desktop, one from app, since both are showing this behavior.

I now have two RT-AC68Us configured for AiMesh with WiFi backhaul. They are about 95' apart on one level spanning 3 interior walls/kitchen and 2 exterior brick walls. This is to upgrade an RT-AC68U and RT-N66U in extender/repeater mode. The old setup worked but the roaming, multiple SSIDs, and management were not very elegant. Plus I need to push the RT-N66U over the hills and through the woods to Grandma's house.
o Set DNS servers (OpenDNS 208.67.222.222, 208.67.220.220)

Just curious why the decision to use OpenDNS vs the built in trend micro? I have been using software at the client level but have been thinking about doing it at the router level.

My use of OpenDNS precedes my use of ASUS routers. I did not realize there was a Trend Micro option... but even so, I like to spread the love around. OpenDNS is reputable and it's not Google.

I only mentioned OpenDNS here to provide context... it's currently in my router and in my notes!
