Release Asuswrt-Merlin 386.12 is now available for AC models

Dirty Flash!

GT-AX11000Pro. So far so good.

...

Have you got the correct thread?

I have frequent asd/dcd errors, and micro-crashes with 386.12_4 on AC86u every few hours. So as an experiment, I disabled all of Trend Micro stuff by revoking the license. And of course, all the errors stopped right there. No issues of any kind. Re-enabled the bulk of TM things today (except for DPI - traffic analyzer) - back to the dcd/asd errors and micro-crashes.

The situation reminds me of this post here:

Sporadic crashes in GT-AX11000 with Merlin 386.3_2 and 386.4 (TrendMicro license as the cause)

The router started crashing and rebooting several times a day. I think it started happening after the update to 386.3_2, but maybe I wasn't noticing it that much before. The network consists of an AI Mesh with 2 additional routers (ZenWifi AX and RT-AX58U), as well as an old Asus RT-N66U in AP...

I now wonder which version of TM engine is built into 386 releases. Is it stock 386 TM code? Nothing is borrowed from 388?

For those wondering, here are a couple of scripts for TM on/off (I diffed nvram dump before and after TM license revocation). I guess need to reboot after these scripts.

tm_on

nvram set bwdpi_db_enable=1
nvram set wrs_app_enable=1
nvram set wrs_enable=1
nvram set wrs_protect_enable=1
nvram set TM_EULA=1
nvram commit

tm_off

nvram set bwdpi_db_enable=0
nvram set wrs_app_enable=0
nvram set wrs_enable=0
nvram set wrs_protect_enable=0
nvram set TM_EULA=0
nvram commit

Setting everything to on but keeping DPI off [bwdpi_db_enable=0] did not help with dcd/asd crashes, still happening.

They don't call those Trash-80's for nothing.
I can't believe anyone would use that always failing piece of **** for a handle name.
I lost many a term paper and backups to that POS. It was a system wide problem that students had to endure.

No I don't lol. It was late, I was buzzed. Although I did dirty flash to my AC2900 and it's working fine, so there's that.

I know it was a piece of shirt. It was my first computer, hence the choice for a username. I had my most fun on a 64C.

Storage was an audio cassette recorder (on my 16K Model I I paid $999 for). What'd you expect ?

When I go to use my Apple TV for the first time after it’s been in standby for a bit, (I don’t know how much downtime it takes for the prob to manifest exactly), the Apple TV is now all of a sudden getting assigned a random IP address. — But it has a reserved IP address on the router, which has never given me any issues.

I tried entering the correct ip address on the Apple TV device manually, but this does not resolve the issue. (The device is usually set to AUTO dhcp — the ip address is reserved on the router using the Apple tv’s MAC address.)

The problem is not resolved by rebooting the AppleTV, nor is it resolved by restarting various services (DNS/DHCP, VPN, Entware) using SC Merlin. It is however resolved by rebooting the router.

I have never experienced this issue before. It started sometime in the days following update to 386.12_4 (though I don’t *think* it was an immediate development but rather one that only closely followed the update. Maybe a coincidence?)

The Apple TV is connected to the router by Ethernet cable . I swapped the LAN jack that it plugs into — issue still came up. There have been no updates to TVos during this period.

It does not happen every time.

Any thoughts?

Manual DHCP assignment is handled by recognizing the MAC address of the device that you want to have a custom IP address. Many new devices now have a feature that sends a random MAC addrress to the wifi router to limit tracking. This feature is typically enabled by default. Your Apple TV is probably set to provide a random MAC address to the router. The setting can be found in the network settings section of your Apple TV.

I keep getting these on my AC5300 with AIMesh on AX88U node:

I disabled the firewall to avoid those crashes for now.

Disabling your router's firewall is usually a bad idea unless you have another device blocking attacks from the internet.

 

[bennor]

I disabled the firewall to avoid those crashes for now.

Disabling the firewall on the main router is usually a very, very bad idea for a whole host of reasons.

Guess I'll be the one to ask. Why are you not using the RT-AX88U as the primary router and the AC5300 as an AIMesh node:

 

[bscabl]

Finally got around to updating to _4.. noted no dcd crashes.. 1 single asd crash shortly after boot... keeping an eye on the log.. bandwith seems normal and unaffected by that one crash..

I re-enabled traffic monitor [as I used it regularly before the dcd issue] - did NOT enable other trend micro things. rt_ac3100

Traffic Monitor was never part of TrendMicro engine firmware options. Traffic Analyzer is using TrendMicro engine.

What's the point of enabling the firewall if it constantly crashes? =)

Would it be any difference if I swap?

You should really give it a try.

Asus has declared the AC machine to be at end of support from them IIRC.

This isn't catastrophic: your AX router is a significantly more capable machine than your AC router, which still has useful life:
I'm certain you'll notice at least a slight upgrade to your mesh network by reversing their roles, and another if you de-mesh and use the AC machine as an AP rather than a node.
Further, it'll harden the security of your network now and moving forward, as your model of AC router will stop receiving (Merlin) updates sooner than the AX.

Depending on your home (or wherever you use these pieces), you might not even need the AC router. There are users here who have found that the AX models easily have more impressive range/coverage from their radios.

 

[bennor]

heysoundude's reply pretty much nailed it. You really should swap around the routers and see if you even need the AC5300 as a node or access point. Some have indicated getting better WiFi coverage with AX series router(s) than the older AC series router(s). The AX88U supports WPA3 for those WiFi clients that support it. Potentially up to double the maximum Wifi speed for those WiFi clients that support it. And the AX88U may have other newer firmware features not found on the AC5300.

Because other things you don't know about yet may start working all of a sudden.

Well after running stock 51668 on 2 nodes its seems that 12_4 is more stable despite being based on the same merge, Hmmm
