    AiMesh randomly disconnecting - "MISC: wifi upstream is connected, and disconnected from CAP."

    I am running a 2 router AiMesh, AC86U and AC68U, both on Merlin 386.14_2. (added later) The backbone is the 5Ghz band, and there is no wired connection between the devices. Pretty randomly AC68U node disconnects, and then reconnects. I reboot AC68U daily, so it's fresh. I tried another AC68U...

    AiMesh nodes - best practices / scripts / etc

    I have a fairly feeble AiMesh setup, AC86u as the main router, and AC68u as an AiMesh node. My main router is rebooted daily, but the node was just sitting there for weeks of uptime. Anyway, it would become somewhat flaky after a while - so then why not just reboot the AiMesh node nightly too...

    Entware Where is Entware started upon reboot?

    Alright, I was chasing the mysterious error I was getting from dnsmasq - link. And it took me down this rabbit hole below. I've taken this out of the post in the Diversion thread, for better visibility. The story is below. But the key question is where are different Entware related things are...

    dnsmasq: failed to create listening socket for 192.168.1.1: Address already in use

    Alright, my router: RT-AC86U. A few addons, rebooted nightly on schedule by cru. 5 4 * * * /sbin/service 'reboot' #ScheduledReboot# Since about version RT-AC86U_386.12_6, give or take, in certain configurations I get this particular error upon auto-reboot once every few days: Sep 25 04:06:56...

    AC86U: boot the prior "bootfs_update" mtd as is?

    A slightly esoteric question. As far as I understand, my AC86 has 2 sets of system partitions, one active, the other contains the prior firmware, and will get the next one (_update partitions below). admin@RT-AC86U-9988:/# cat /proc/mtd dev: size erasesize name mtd0: 05aa0000 00020000...

    Where is the cache of known MAC addresses stored?

    Sorry if trivial question - could not find it with a few minutes of search. If I plug in a rare device that was offline for a while, DHCP will still assign the same IP address to it as last time - many reboots ago. It sort of seems this info has to be cached somewhere. Any idea?

    FYI: AM 386.12 on AC86u - how to decrease # of random reboots

    I was trying to fix random reboots on my AC86U with AM 386.12_4 that is running AiProtection and other proprietary features. Even daily auto-reboots would not help - the router could crash-reboot even after an hour or two in operation. Also, lots of issues like this were discussed in the...

    Scribe /usr/bin/logger messages don't make it to the log file - intermittent issue

    I am running Scribe with Entware. Sometimes my cron job messages don't make it to the "messages" file for stretches of time, then it's all fine again for a while. Here is an example of a cron job that I want to output to messages every 15 min: cru a temp "*/15 * * * * /jffs/scripts/temp_check...

    AC68u fast blinking power light from time to time (nvram issue)

    I have this flaky AC68u which from time to time totally forgets its NVRAM. Usually power light is blinking rapidly. I can usually restore the router after multiple attempts of pressing WPS button upon turning on. It'll come back up fully factory reset. But it'll forget again soon. I am using...

    uiDivStats Lots of disk writes due to fully re-writing file ./entware/share/uiDivStats.d/csv/SQLQueryLog.htm

    I was chasing pretty substantial disk writes when using amtm scripts (~2GB per 24 hours), and one of big writers is uiDivStats Basically, the entirety of file ./entware/share/uiDivStats.d/csv/SQLQueryLog.htm get re-written every minute or so. That's good 300kb, plus probably journaling on top...

    Router temperatures - 2023

    Sadly, the prior thread just expired - 6 months inactivity limit ... https://www.snbforums.com/threads/router-temperatures.71123/ This is a great post - even if I am late to the party! I thought at first to stick a copper shim on the cpu in AC86u, but let's face it - it's not the cpu that...

    amtm ext4 partition with journaling - 15 GB size, 1150 GB of writes in 20 months

    As I was slightly re-partitioning my external AMTM drive (a very low end dram-less 240GB SSD hanging on a USB2/SATA ~10 inch adapter cable), I noticed something really interesting. In 20 months this partition with Entware and a 2 GB swap file had 1152 GB of disk writes. So this is about 2GB of...

    Scribe A filter to drop kernel dcd tainted errors :

    My AC86U router produces endless kernel dcd errors due to AiProtection features which pretty much pollute the system log and make it impossible to look at in a fairly efficient manner. See such a dcd error message below - it's huge for each error instance. So I put together a new quick & dirty...
