Three people have confirmed wlan1 is busted on r45229 for WRT3200ACM. No configuration required.
Tried all three resets, same result. Wireless interface wlan1 description is empty.
The only Wireless Network Mode available is Mixed.
Odd, it's there and working for me. Only issue is that changing WiFi settings causes the WAN connection to reset. 5GHz also seems mildly unstable after running for a day (occasional reconnects when a device has been idle for some time).
I’ll be happy to try setting changes if I can figure out exactly what they are (I’ll look for your signature settings). But, at least for the problem I’m experiencing, the issue seems to have been introduced in a pretty narrow range of commits (44048-44112). Were any of those settings altered in that range (I’m using the same config backup file for anything in that range)?
It’d be great if a true root cause could be determined here since this issue feels like it might be a first big hiccup for 3200ACM’s causing all sorts of other mysteries in later builds.

As msoengineer hinted, Beacon Interval does indeed matter on these radios. On 44048 anyway, you need to keep it at the default 100 or terrible things happen. In my case iOS devices had real issues when I changed it even a little. _________________ 2x Netgear XR500 and 3x Linksys WRT1900ACSv2 on 53544: VLANs, VAPs, NAS, station mode, OpenVPN client (AirVPN), wireguard server (AirVPN port forward) and clients (AzireVPN, AirVPN, private), 3 DNSCrypt providers via VPN.

I've been OK with either 1 or 2. I'm using one of those values on 2.4 GHz and the other on 5 GHz, though not for any meaningful reason. That's just where they happened to be when I realized putting BI back to 100 fixed everything. _________________ 2x Netgear XR500 and 3x Linksys WRT1900ACSv2 on 53544: VLANs, VAPs, NAS, station mode, OpenVPN client (AirVPN), wireguard server (AirVPN port forward) and clients (AzireVPN, AirVPN, private), 3 DNSCrypt providers via VPN.

So what exactly is the solution? with the most recent firmware to make the apple devices work, do I have to change the wifi parameters? which ones exactly? can you point them to me? , thanks _________________ Linksys WRT3200ACM AP 1

I honestly don’t think anyone knows what “the solution” is, because no on truly understands why 3200’s stopped working in the first place. There’s a lot of speculation and twiddling of parameters here and there, which has been really tough for people unfamiliar with WiFi design and the internals of the 3200 devices to understand. But I think that’s all just been masking whatever the root cause might be.
I wish I were more knowledgeable about these things as well, since I work in the technology field. But the time required to obtain the knowledge I think might be needed to get to the bottom of this is likely great. So all we can do as normal ddwrt users is read what we can and try out what is suggested and provide as detailed feedback as we can. Msoengineer has links to various 3200acm config hints in his signature so I plan to try to work through those. A compiled list of recommended 3200acm settings would be nice to see, but I kinda doubt that will happen unless someone finally happens upon a set which actually works and brings 44048-like reliability to recent builds.
The last version I tested was 44970 before falling back to 44048. The problem can be easily reproduced on a WRT1900ACSv1 too - it's not specific to a 3200ACM. Over the course of many releases this Fall, I tried different channels, channel widths, RTS/CTS settings, and sensitivity range/ack timing settings. None helped. My BI has always been 100 and my DTIM has always been 2 - I've never tried playing with those settings.
Here are wifi settings I have in-common between 5ghz, 2.4ghz, and both the 3200ACM and 1900ACSv1:

pbphoto... My WRT1900ACSv2/44048 setup mostly mirrors yours, but for one item: earlier this year I found that moving protection mode from none to RTS/CTS produced occasional wifi issues so severe - inability to connect at all - as to require a reboot, maybe every week or two. It all cleaned up nicely when I went back to None. This was seen on three different routers in different parts of the country (different ISPs) with similar but nonidentical setups. _________________ 2x Netgear XR500 and 3x Linksys WRT1900ACSv2 on 53544: VLANs, VAPs, NAS, station mode, OpenVPN client (AirVPN), wireguard server (AirVPN port forward) and clients (AzireVPN, AirVPN, private), 3 DNSCrypt providers via VPN.
Thank you for the tip. I believe I tried that in the past but I will try it again. Wondering if you have Apple devices in your environment? Just to be clear, I have no issues with my setup and Apple clients on 44048- only when I go to a newer release do the Apple clients start having issues.

Lots of Apple things here. iPhones of various ages. iPads of various ages. An ancient Mac. The other two locations/routers involved are also heavy Apple homes. _________________ 2x Netgear XR500 and 3x Linksys WRT1900ACSv2 on 53544: VLANs, VAPs, NAS, station mode, OpenVPN client (AirVPN), wireguard server (AirVPN port forward) and clients (AzireVPN, AirVPN, private), 3 DNSCrypt providers via VPN.
Someone has tested the r45229 with apple devices? _________________ Linksys WRT3200ACM AP 1
