RT-AC86U running 384.14B1.
I have a mesh network which includes a hard-wired RT-AC68U and a wireless DSL-AC68U. (both on latest stock)
For the last couple of weeks the mesh network has been unstable and cannot maintain a reliable connection to both nodes. I've also been having issues in the last day in being able to see all of my Chromecast devices. If I reset the wireless on my phone, some devices become visible, and others remain invisible, despite all of them being connected to the Internet and are able to respond to voice commands independently.

I gave all of the routers a full power cycle prior to going to bed last night and woke to find that the RT-AC86U had dropped its config completely (presented with the initial setup Wizard).

Anyway, not much in the way of diagnostic information to provide other than that vague sequence of events. I've never had the config drop itself like that before.

My wife has a Google Nexus 10 tablet running Android 5.1.1 that refuses to connect to 384.14B1. I have switched back and forth between that and 384.13, with no luck on 384.14B1. In fact, after the router has been updated to 384.14B1, it won't connect to it once it is running 384.13, again. I have to do a complete factory reset and set my network up again in order to get the Nexus 10 to connect.

Finally, I discovered that after I switch back to 384.13 and then set up a specific guest channel for the tablet, it will connect without resetting the network.

It's probably something simple that I am missing...

I also have a Verizon Ellipsis 10 tablet on the same version of Android, and it has no issues, whatsoever (other than being a Verizon Ellipsis 10, of course).

Does anyone have any idea what could be causing this?

Are you using different SSID's for 2.4 and 5 GHZ radios?

Yes. They are the same name, but the 5G adds the suffix -5G

The guest network has a completely different name.
If you have the -5g suffix the SSID's are in fact different. Insure the 2.4 GHZ band is using only 20 MHZ bandwidth on a fixed channel (1-6-11) and the 5 GHZ is on a fixed channel (try 36 -r 149). Also try turning off beamforming.

I have done the first two, so I will turn off beamforming tomorrow and see if that does the trick.

Thanks!

If you are having JFFS2 or dnsmasq issues with the RT-AX88U, please try the beta1-g02edc51d7e test build available here:

https://www.asuswrt-merlin.net/test-builds

JFFS2: after booting, check if the partition is mounted. If not, please post the output of the following commands:

Code:
cat /tmp/jffs2.log
nvram show | grep jffs2_
RMerlin,
This is what I get, hoping that it is useful input

Code:
cat /tmp/jffs2.log

(Factory reset with 834.14 beta1-g02edc51d7e)
About to mount it
start_jffs2

Thank you. Looks like Asus broke things with 384_6436. If the router is set to erase the JFFS content, it will unlock the JFS partition for writing, however it now incorrectly checks whether this was successful or not. I'll fix it, please give it another try once beta 2 is released.[/code]

Interesting... 384.14 beta 2 on my rt-ac86u seems to use much less memory then before . 82% vs 74% on beta 2. Is there an explanation RMerlin , did you see also drop in memory usage (which is great of course) :? (and also the 74% with swap file at 0 mb)

There was an Asus timezone (TZ) fix in httpd that says it’s related to a memory leak. Could be part of the reason.

I have been on the Beta for more than a week and so far encountered no issues (still having AX, 160Mhz and DFS disabled).

Can I ask if the Wireless Site Survey section is working well for everyone? It is showing no measurements at all in my case.

384.12 beta 2. Typo?

I have found that sometimes (If you change a channel for one of the radios for one instance ) the only way I can get the site survey to work again is reboot the router.
