Just installed a new old stock XR500 and immediately loaded this build. Finally ditched a R7000 that would lose all config after power outages randomly.
After flashing the XR500, I performed "nvram erase" via telnet. Then I manually set all my firewall rules, static leases, etc via GUI.
Issues: The 2.4 Ghz LED is not lit or blinking but connectivity works. Anecdotally, I have lost 5 Ghz connection on my phone and another household member's phone. A router reboot resolved this. I then changed to Short Preamble since that was what I had set on the R7000. Will monitor more today.
I discovered that I was losing Wi-Fi on my phone because of a Randomize MAC setting on the phone's advanced network settings. I have had this enabled with the R7000 and it was not an issue.

Well for home routers, this is very well known bad practice.... you'd need to disable it…as well Broadcom wifi drivers are different and this is not even radio drivers related, but rather dnsmasq and dhcp daemon settings…. _________________ Atheros

Given that a Randomized MAC address of a mobile phone minimizes its (MAC) tracking when on the road, it's a good practice to use. Instead of using actual phone MAC.
At home, it can be inconvenient, however, if its IP keeps changing. Of course, it can be turned off while @ home, then one needs to switch back to it when leaving home. Pain in the neck.
Best compromise is locking its randomized MAC with a STATIC LEASE when it first connects with the home router. (See: Services/Services/Static Leases).

I have an Android phone, not an iPhone, but I can set MAC randomization by connection. I have it turned off for my home SSID, but when I connect to public wifi, it's on. Considering the feature parity between iOS and Android, I expect it's possible on iOS too.

I've had my Android phone's randomized MAC locked to a Static Lease for a while and I did not notice that it is per connection. Good to know. It's certainly a clever feature by phone makers. My wife is accustomed to using iPhone. Long before Signal and Viper apps level the playing field by Apple's monopoly of its Facetime.
On an extended topic. I no longer use free public wifi nowadays due to security concerns. For o/s travel, I'd get a local SIM card at destination for on-the-road needs. While at accommodation such as airbnb, we use host's provided wifi via our own a travel router. With VPN encrypted.
One can't be too laissez-faire nowadays.
I can't maintain a 5ghz wifi connection to the Internet on my Samsung S23. It's fine for about 10 minutes then connects to the AP with no Internet access. Other devices seem okay. 2.4 seems okay. The issue is not related to the Randomize MAC setting. I thought it could be related to my DHCP reservations which I had set up in DHCP Server Setup Additional Options. Then I deleted that code and reset that all up as Static Leases instead. Then I removed all of that to simplify. I have also tried Vanilla vs. DDWRT Wifi firmware option.

Not sure what else to try.
I have the s23 and there was an update about a month ago (on Cox) that did all kinds of wonky things..which happened to coincide with some changes on ddwrt so my two advice notes are switch to the latest 61848/6-24 version or earlier than when the arp was added..a few months ago. I dont think arps the problem, but that way you dont need to worry about it.
You probably have to redo your connections in android. So just forget them and do a new connection from scratch, its been covered in the s23 forums. But let us know what version ur currently on just to see if it matches what I was experiencing. AND make sure you have the latest s23 updates..they have been fixing what they broke the last few weeks so both mine and my wifes s22 (on verizon so updates a bit different timing) both had similar issues, for her even at work....govt maintained wifi...
Also if still giving you trouble, you can probably do a static connection on the phone itself if your provider hasnt got the latest latest fix, but the one from this week seems to have fixed it for good. Surprisingly, my old not updated for like 3 years amazon tablet had no issues, so its mostly all on samsung or the carrier screwing around with things.
I decided to upgrade my phone. I found other posts that this is an issue with the S23. I have tried everything possible.
Network Mode Mixed, N/A Mixed
Short Preamble on/off
Airtime Fairness on/off
Firmware Type DDWRT/Vanilla
Channel: various
MAC random or phone MAC
Forget, readd WIFI connections
Happens on both 2.4/5 ghz.

I now have a worse problem. New post incoming...
im on the mx4300 but on all three running
Network Mode AX/AC/N Mixed
Channel Width 80
Short Preamble on
both single and multi user beamforming on (this depends on router and such)
Airtime Fairness on
Firmware Type DDWRT
Channel: 116
MAC random or phone MAC
Note that I am running on wlan 2 on all three routers because 0 is the backchannel for mesh.
Have not had problems on s23 or s22 since upgrading to 61848...but I think my wife's phone took an update a bit later than mine to resolve.
Also running domain panama for wireless and I recommend trying static on phone first, see if it maintains and then switch to dhcp. NSS is on on main router. I did have more problems in the time this was really being a problem on 2.4 ghz with initial connection on main router but not on waps...at least that i noticed.
