My experience with the RT-AC86U

[maxbraketorque]

Here is what I see, AC86U and AX86U compared side by side to test AC clients at the same locations - same room 3m away, behind one wall 10m away and behind 2 walls 15m away, plus some more differences:

- AX86U shows 4dBm lower signal strength from clients on all channels, perhaps less sensitive radio.
- AC86U can do >60Mbps real transfers on channels 36-48, but no more than 40Mbps on 149-161.*
- AX86U can do >60Mbps real transfers on channels 149-161, but no more than 40Mbps on 32-48.*
- 2.4GHz band is exactly the same on both, same dBm reported and same transfer speeds.
- despite the dBm differences on 5GHz band, I would say both routers have identical performance to AC clients, just need to be set differently.
- I tried to crash AX86U with my test transfer to USB attached SSD and it survived, AC86U doesn't. I've seen this on AX88U though - 1GB RAM.
- AX86U LEDs are much brighter than the LEDs on AC86U - a bit uncomfortable, if the router is used in a dark room.
- AX86U WAN LED blinks differently when WAN port is used and when 2.5GbE port is used for WAN. I like 2.5GbE port LED better.
- Asus App can't restore AX86U LEDs after turned off, no LAN LEDs coming up. Works in Asuswrt-Merlin GUI though. Minor inconvenience.

* - Wi-Fi environment specific

I have the router for few days only and had no much time to play with it. The case is a bit cheap plasticky looking, the antennas were not aligned perfectly and needed slight force adjustment. Acceptable for $250 router though with good hardware inside. I like the normal power jack and the new switch, but there is a design flaw - on/off switch is at the wrong side of the power jack and is too close to it. It's a bit hard to reach.

I had to open a new thread for this comparison information, apologies @Oracle.

Thanks for the comparison. I guess I can stop contemplating purchasing an AX86U, at least for the wifi performance. There will be an edge for router VPN performance.

The LEDs can be made dimmer by coloring over them with a black Sharpie. Still visible, but much dimmer. It works great.

 

[Tech9]

black Sharpie... It works great.

No.

 

[maxbraketorque]

No.

It really does work, and it looks fine when the router lights are disabled. Also, keep in mind that Sharpie comes off with rubbing alcohol, so its a reversible mod.

 

[Tech9]

It really does work

Probably, but not my way of fixing things.

 

[SomeWhereOverTheRainBow]

Probably, but not my way of fixing things.

I put black electric tape over mine... much more pro-mod. Something I learned somewhereovertherainbow. But, I don't go back any more. Too many pro-mods. Too many chiefs in the kitchen.

 

[Oracle]

Some more running time and some more observation: changing pid_max still doesn't appear to make a difference.
The stuck commands keep coming.

I'm now interested to simply and combine the 2 override scripts (for nvram and wl) into one, so it's easier to install, use and maintain. The overrides are the best solution we have so far.

As I said, it wasn't intended to stop the problem just make it less frequent. But YMMV depending on what you're running on the router.

Well, the timeout command is also super-duper handy... that's been my go-to fix for many, many months now -- at least, within my own scripts - not on a system-wide level.

Initially I can run nvram test script with no issue. Until I run the script by @Martinski that reveal I do have some stuck process. Those stuck process does not affect nvram get script though. After clearing those stuck process then the nvram script get stuck. I remember the first time I change pid_max nvram script still fail. I rebooted, change pid_max and leave it.

Something I have noticed for some time is conn_diag db file. My conn_diag db file usually stuck and not updating a day or two after reboot. After change pid_max the db files keep updating every minute. I have it for about a week in 386.5_2 and now three days in 386.7. The last time Martinski’s script detect stuck process is on 19th Jun. Changing pid_max works for me.

 

[Oracle]

Well, the pid_max change might be making a difference.
The rate of wl errors is the same but nvram errors haven't popped up yet after 3 days of uptime. I don't know what to make of these stats yet. (Not available means 0 errors.)

Usage statistics of nvram and wl overrides
Uptime: 09:02:20 up 3 days, 16:13, load average: 2.68, 2.88, 2.95
nvram use count: 11890
nvram errors count: not available
wl use count: 21098
wl errors count: 6

@chongnt, any response from Asus on your bug report? Shall I try to push from my side?

As a side note, I wish there was a build of Merlin's firmware without the bloatware (closed source features that rely on sending your traffic data to a third party to exploit it). That would give space to include more valuable stuff instead but I realize that's too much to ask for.

Unfortunately I have not get any feedback from my local Asus support. Appreciate if you can push from your side too. Hopefully they will treat this with higher priority with more reported case.

 

[Oracle]

After nearly 7 days of uptime, it looks like the pid_max change clearly has an impact on the nvram get stuck commands (so far 0 stuck) and not on wl (14 stuck).
I thought these 2 were manifestations of the same root cause but there's a difference now. Or maybe there is something else at play here.

If you run this script followed immediately by ps w and post all the results in that other thread we might be able to guess what's happening.

 

[Oracle]

Any conditions as to when do I have to run the above? Is it ok that I have the nvram and wl command overrides active? (They kill stuck processes and retry the commands.)

No idea. There's too many moving parts in play and I'm not intimately familiar with everything that's run/running on your router. Just dump the information as-is and we might get lucky and be able to spot something.

I have this too.

chronyd[4658]: Can't synchronise: no majority

I am on RT-AX86U though with 386.7 firmware

 

[dfunked]

I use an AX86U as my main router, but couldn't resist snapping up one of these at a relatively good price (under £100)
It's been running like a champ as an AImesh node, and even though I could just get a new router tomorrow if I needed to, it's nice to know that I've got a capable one already in the house that I can just factory reset and have up and running again in no time.

If I was in the market for a new router tomorrow for whatever reason, yeah I'd probably be looking at the AX86U (or the pro now I guess), but early failure rates aside this is still a solid bit of kit.
