RT-AC88U: RTK Switch initialization fails

[TheUntouchable]

Hi guys,

I don't know what this is, but it started suddenly with one of the betas in the past.. It doesn't appear directly after a reboot or a flash, but at different times after running the router for some days.. Its flooding the logs with that message and only a reboot fixes it I have the feeling.. Any hints about that problem..?

Problem with the Realtek switch that handles ports 5 through 8. Unplug the power from the router for a few seconds then plug it back in to completely reset the controler.

 

[TheUntouchable]

I have done this quite often, unfortunately the problem reoccurs after a while So I think this is a hardware problem..? Would be very sad after I no longer have a warranty on the device..

 

[RMerlin]

Yes, unless you have a buggy device plugged into one of these ports, and that devices is causing the switch to crash.

 

[TheUntouchable]

Actually, I don't use these ports, so this possibility is unfortunately excluded.. Would be the AX88U a good upgrade in your opinion?

Yes, unless you have a buggy device plugged into one of these ports, and that devices is causing the switch to crash.

I've never used these ports (5 through 8) with my AC88u since December 2016, the date I bought my AC88u. Last week I saw these a couple times with 314.18 but since I still don't use Realtek ports I just ignored. Running 314.19beta 1 for 3 days and I didn't see these logs.

I have the feeling that this also started with 314.18, still there with 314.19 beta 1.. But same here, I didn't use that ports since I bought the router

I came here after seeing the same error on my device, I only recently purchased mine and it is on the default manufacture firmware. It causes a minor inconvenience as the TV has a pop up box advising it has lost a connection and then again when it is working again.

Just thought I would add something here due to the error being seen in the default firmware, I will be raising a case with Asus support.

It's not a firmware bug, it's a hardware issue. The log is simply telling you the Realtek switch is no longer responding. Power cycle the router to reset it, that fixes it in most cases.

I just observed a number of Realtek log entries in my AC88U log this morning after upgrading from 384.19 to 386.1 beta 1 -- I have never encountered this before. I am also not using ports 5 through 8. (EDIT: I was using port 5, so that last comment was incorrect. I just power cycled the RT-AC88U and I no longer have anything plugged into ports 5, 6, 7, or 8.)

@RMerlin I will power cycle the AC88U and keep an eye on the log.

I mostly see messages with err=-1:
rtk_port_linkStatus_get() fail, err: -1

But there are a few entires with err=14 and one entry with err=10

I wonder if Asus has used the Realtek RTL8365MB in a number of router models or just the RT-AC88U.
