Questions:
1) In Status/Bandwidth, why does a graph display for Bridge br1 but not for Bridge br0? Is there some way for me to add one for br0?
2) In Services/VPN/OpenVPN Client, I've noticed that the Server IP or Name that I enter in the box gets overidden by any backup IP or name in the Additional Config:
So I've had to list the primary server twice (in the box and again in the Additional Config for it to be used at all, but then the backups can't be random if I normally want the primary):

remote-random means randomly choose a server from your list, so that is not an option you should add if you want to connect to the first server (which is the one in the GUI) first.
It is just one list of remote servers, either go down the list starting at the first (which is the one in the GUI) or use random _________________ Routers:Netgear R7000, R6400v1, R6400v2, EA6900 (XvortexCFE), E2000, E1200v1, WRT54GS v1.

Full DMESG log until fail situation occured attached. Same behavior as 3 previous builds. Further errors:
Clients loosing connection over time. Same issue as described by others. Hits IOS clients first, but the same on a Samsung Mobile (S9+) and 4 Raspberries (2x PI3's, 2x PI4'S). PC's more stable - but also wifi lost eventually.
Reverting to 45993 once more. Last build without the httpd error in my setup.
Additional info: Reproducing - Reboot from terminal - this time directly into httpd crash. DMESG log created if thats needed for further investigation. Seems intermittent though...
At least last two update broke something on hostapd on my WRT1900ACSv2, and even with last beta (DD-WRT v3.0-r46177 std (03/26/21)) I get same problem.
I randomly have wireless connection hang down, new deviced can't connect and already connected device can't do traffic. I have to connect with wired device but I can't get DHCP from router and can't open http. I only have access via ssh and this is the content of messages log:

Makes sense and confirmed, thanks! The above was on a WRT1900ACS v1. Below is on a WRT1900ACS v2.

Question: But then, in order to take our ACSv1 offline so I could attempt replacement of its fried LEDs today, I restored the ACSv1 backup of same build to the ACSv2. Immediately after reboot (before I'd even regenerated the FreeRadius cert and info in jffs2), the ACSv2 exhibited ~3 second lag between switching webif GUI tabs. It was still the same ~3 seconds (compared to ~0.5 seconds normally) even after FreeRadius cert generation completed (because FreeRadius info doesn't restore with nvram restore, I assume since stored in jffs2 that doesn't get backed up rather than standard nvram that does get backed up). So it appears that although restoring an ACSv1 backup to an ACSv2 technically works, it seems to result in the lag between GUI tabs (at least with my setup including FreeRadius Server). Cleaning jffs2 before and after GUI reset, and again after restore, hasn't resolved the post-restore lag. I'd love to figure out why. Any diagnostic suggestions (e.g., pertinent logs and/or variables to check)?
EDIT:
SOLVED! I can't explain why, but after I went through the above a third time and it was still lagging under a clean instance of FireFox, I opened instead under PaleMoon and the the lag was amazingly gone. Then I opened in FireFox again and the lag was also gone. It doesn't make any sense to me, but it's working well and I'm currently connected through the ACSv2 after restoration from ACSv1 backup. Everything's back to normal. Now, on to replacing those microscopic LEDs...
QUESTION #2: Is there a straight-forward way to backup and restore the FreeRadius information (certs, clients and users) stored in jffs2? _________________ My DD-WRT Routers:

Thank you.
I'm not having any hostapd issues with r46177 on either of my units. It looks like one client on the ACSv1 (up 7 hours), a non-standard Android 7 projector, randomly failed authentication once but then succeeded 9 minutes later. I'm pretty sure it was in low-power standby mode at the time, so that's not unexpected. The other 8-10 clients have had no issues at all, and hostapd has been up continuously and getting a good workout.
My only concern at the moment is temperatures on the ACSv2. Both my ACSv1 and ACSv2 are pretty evenly loaded, but the ACSv2 is running much hotter than the ACSv1. So hot, in fact, that I'm considering shutting it down until I can mount a fan on it:
ACSv1:
Load Average
50%
1.00, 1.00, 1.00
Temperatures
CPU 76.0 °C / WL0 43.2 °C / WL1 44.3 °C
ACSv2:
Load Average
52%
1.04, 1.01, 0.99
Temperatures
CPU 82.2 °C / WL0 45.6 °C / WL1 48.0 °C
I don't think my Netgear routers even reached 70 C when overclocked from 1000 to 1400 MHz. 82 C for the Linksys ACSv2 running its stock 1600 MHz seems bizarre in comparison. They're clean (I occasionally run a vacuum over the vents) and the indoor temp here is around 20-22 C. Has anyone ever seen router CPU temps like that? I've just ordered an AC Infinity Multifan S3, FWIW. _________________ My DD-WRT Routers:

Your devices seem to be heavy loaded, with one core maxed out, those temperatures are to be expected.
System load avg over the last 1, 5 and 15 minutes 100% for one core .
Either you run some really hungry applications, or a process fried / isn't configured correctly.
Adding a cooler will only lower the temperature, but not solve the root cause:
Something stresses your devices.
Never seen this on my end, even under heavy load.
--> not normal.
My advice: Reset and configure from scratch, do not import backups. After each step check load.
When done, proceed with the other device.
DO NOT IMPORT backups from v1 to v2 and vice versa.

Just an interesting note to the "wifi issues", wifi tends to be problematic on most of my "newer" devices, however, I have a single Apple Gen2 IPad that I still use for assorted low volume tasks. I have zero problems connecting, and staying connected on 5Ghz HT40/HT20.

Thanks! The heavy load was due to a known app and generally expected, but while it was running I took the opportunity to compare the different loaded temperatures of the ACSv1 versus the ACSv2, and was surprised by the difference (and especially the 82C CPU of the ACSv2). I'd previously noted the ACSv2 running a degree or so hotter than the ACSv1 under light loads, even when their roles were reversed, so I had it in my mind to compare more scientifically when more heavily loaded. Unlike the ACv1 but like the ACv2, neither of the ACSv1 nor ACSv2 comes with a fan. I hadn't realized the app was limited to using just one of the two cores, which became painfully obvious on at least the ACSv1, so I guess it might not have been a fair stress test after all. Anyway, just to be clear, I don't think there are any gremlins here (other than possible heat-sink and/or airflow issues). Both are under lighter loads most of the time:

Enabling WPA2-SHA256 caused me trouble a while back (with devices that supported it seemingly preventing other devices from staying connected, IIRC), so now I only use WPA2 (without SHA256) and WPA3. I also have just one or the other enabled per wireless interface (two physical, generally plus two or more virtual), which should at least make trouble-shooting easier. Mine happen to be bridged separately, but it's easy enough to bridge them together if you like. I've had no wifi issues whatsoever handling it this way with a variety of clients, including both old and new Apple devices. All seem to get along fine using this approach. _________________ My DD-WRT Routers:
