I still have random reboots on my both RT-AC88U. This happen with all builds more or less i tested during the last months. Is there any more information i can provide to troubleshoot this issue. One is the gateway router using DHCP, MAC filtering, DynDNS and port forwarding. Thes second one is an simple access point with MAC filtering. I actually have an external syslog server to log the info for both of them.
I ran into Daily Reboots on a R7000 at Off Site #2. I make some configuration changes and seemed to fix it but the problem came back after a week. I replaced the Power Supply and put the configuration back normal haven't had a Reboot since. _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone

My second RT-AC88U is quite new (less than a year old) and i don't think it is related to the power supply. I bought it wenn i had issues with my first RT-AC88U (already a few years old now). Later i found that they behave the same way. This random reboot are there more ore less often all the time. Sometimes it happens after a few days and sometimes even after hours. I have scheduled an weekly reboot on all of my DD-WRT routers. I had more problems in the past before i learned to keep the config below 64k. If you go above the 64k the 5g WiFi interface will disappear. I remove major parts of my traffic history on the gateway router to make this happen.

Updating the router to version r48741. For some reason, r48494 is being installed. Previous r48646 same failure. Most likely the new version has not been uploaded to the site or something else

After issues with 2G connections, reported here and another recent thread on dd, I have since hooked my dd-wrt to a serial connection. My steps were as follows:
> Flashed Netgear stock FW via tftp2 and serial CFE, but not before running nvram ease > Flashed dd-wrt.v24-48741.chk via Netgear’s web UI > Ran nvram erase under CFE after initial boot. >
After testing, and a number of resets, I have found that when I reclaim the WAN port, I lose 2G Wifi connections, permanently. I am unable to regain 2G WiFi by tracing back & undoing changes. However, settings restore (from the same build) works, and the router performs as expected.
Reclaiming WAN port for a non-gateway router (as far as I understand it) should be a simple as unchecking WAN from VLAN2, and Placing it on VLAN1 on the Setup > Switch Config page.
I can see a that a code typo was corrected by BS since this build, but I don’t know if this is related. It would certainly be nice to know when I can safely go ahead and reclaim my WAN port.

I could be wrong, but I'm not aware of a wireless setting that causes everything to work perfectly for 4-6 hours and then abruptly stop working, yet that is exactly the issue I'm experiencing.
At any rate, my settings are below. I only use 5 Ghz with 2.4 Ghz disabled. The router GUI shows the clients as connected with excellent signal strength even when they are experiencing connectivity issues. It happened many times across several reboots and nvram erases.

I would have to search the forum to see if Broadcom ARM even supports beamforming
to begin with (since it's not in the applicable wiki(s).
Sensitivity Range (ACK Timing) 1350
(I don't think Broadcom supports auto-ACK?) _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Thanks. I understand that everyone has their preferred wireless settings. FWIW, I mostly followed the recommended BCM settings which are a sticky post in the forum. Also, I have a Netgear AC1450 with the exact same settings I posted above and it works flawlessly. Not sure that my settings are to blame for the issues I experienced with the R7000P.
Netgear Broadcom ARM definitely supports beamforming.

on this build i did experience 5 GHz losing connection 1 time on one of my R7000P's. i had 2.4 GHz running on that router and it still had connection plus internet. usually 5 GHz runs rock solid. i wasn't sure what triggered it. i just rebooted and it hasn't happened again.

Cold boot is still different from soft boot. It's just a different test case. Suspicious problems are better solved by cold boot.

I also added a few more MAC addresses (3) last days to my list. The list has now more than 64 entries. It initially worked after applying this changes, but after a reboot there was no wireless access possible anymore. All five routers refused wireless connections. After switching MAC filter off it started to work again. I also tried a couple of older firmware builds but the routers behave in the same way. The random reboots are now 2-3 times the day for both RT-AC88U. This is very annoying since this are the most powerful and mostly used routers in my network.
