Asus AC68 – “internet disconnected” recent Merlin firmware upgrade

[Boss19]

Thanks for the welcome @UK Sentinal.

Sorry, I didn’t want to bog down this topic with unnecessary info when my agenda was to get into contact with @Grisu.

My issue pertains to Asus AC68 that recently showed “internet disconnected” after recent Merlin firmware upgrade (3.14).  The internet itself is working fine, it’s just showing disconnected.

Pursuant to details from another forum, it seems like the router is set to “manufacture mode” (ie. ATEMODE=1) when it should be in “production mode” (ie. ATEMODE=0), thus the cause for the erroneous WAN status.

It’s my understanding there are 2 commands that will rectify this issue so after scouring the web, I have yet to find such minimalist approach that will resolve the problem.

Any advice would be appreciated.

No Problem and thank you for the consideration, hopefully @Grisu will see this thread and I will drop him a PM, just to make sure ;-)

try SSH to router and enter these commands:

nvram set asuscfeATEMODE=0
nvram set asuscfecommit=1

Then reboot and factory reset to see if it’s ok.

 

PS: First answer with some more possibilities (OC and region-free) with lot of text got error message?!?

text lost and in red showing:

ERROR: Are you sure you wanted to do that?

@GRISU!!!

Thanks for the prompt follow-up and @UK Sentinal for forwarding the PM

The router is a US modded TM-1900. Everything has been smooth until the Merlin 3.14 firmware update which is when the “internet disconnect” problem manifested itself

The router is off-site remote so I probably won’t have an opportunity to try the commands for a couple weeks when I’m on-site again.  I can SSH into it remotely but seeing that you recommend a full reset, and in case of a disaster scenario, I’d rather make changes locally… with a backup router in hand, just in case ;)

Also, just to follow your “PS”… were those the prompts that showed up when performing the commands? (ie warnings)?

Finally, just copy and pasting from other commands… is it possible to run it all in one command with the “&&”:

nvram set asuscfeATEMODE=0 && nvram set asuscfecommit=1

Glad @Grisu was able to help, so you have an ASUS TM-AC1900 which in theory is not supported by ASUSWRT-Merlin, but  the details given by @Grisu helps

Never mention TM.. in snb and we dont ask!

You dont have to reboot or factory, but then you wouldnt know if it works or not.

Only reboot and/or factory will load defaults from cfe and then you’ll see if is 0 or still 1.

Yes, you may combine commands with && for single line. Dont know more you have to read in Linux/Unix world what it means exactly, there are other possibilities too like ‘;’ AFAIK, one will wait for previous to be completed others somehow different, really I dont know, but ‘&&’ will work.

 

My PS is for @UK-Sentinel and has been the output of this forum here, I wrote really much text with some more tweaks.

After enter they were gone and I got this error message.

Nothing to do with the router!

 

Some more for region free (only use channels allowed in your country) in single line

nvram set asuscfe0:ccode=#a;nvram set asuscfe1:ccode=#a;nvram set asuscfe0:regrev=0;nvram set asuscfe1:regrev=0;nvram set asuscfecommit=1

nvram set asuscfe0:ccode=#a
nvram set asuscfe1:ccode=#a
nvram set asuscfe0:regrev=0
nvram set asuscfe1:regrev=0
nvram set asuscfecommit=1

OC to 1000MHz or 1200MHz CPU and 666 or 800 RAM

nvram set asuscfeclkfreq=1000,666 && nvram set asuscfecommit=1

nvram set asuscfeclkfreq=1200,800 && nvram set asuscfecommit=1

1000 is quite safe, 1200 will work on most routers while 1400 will brick most 68U

Before OC in cfe you have to test in NVRAM, so you can reset and load working values from cfe.

Once they are too high in cfe you need a new router! Advantage to do in cfe, they will stay forever and dont revert back every some hours.

@Grisu – Did the ‘Nothing to do with the router!’ message appear after you tried to submit post – is that what you mean ?

Thanks ?

TM… doesn’t it stand for Totally My router… and can do with it what I want ;)

So just to update… I decided to take the plunge and run the commands remotely.

ATEMODE=0  and the “internet disconnect” bug is no longer there.

Thanks again for your assistance…. tracking you down was worth it!

Ditto regarding router (as long a no licensing laws are Broken), just hope the commands remain after a reboot

May need to add at end of commands “nvram commit” to ensure commands remain after reboot.

No, with cfe-commands you need ‘nvram set asuscfecommit=1’ as “write to cfe instruction”.

Glad it worked for you – thats why I am not welcome in snb fanboy forum

And they never accept critism on their terrible buggy firmwares and TrendMicro stuff, thats my point to warn new members.

Oh, TM means TrendMicro

Please post possible resolution over there for others, not the commands – you could refer to here with a google search and proper search string like internet disonnected uktechhub.

If I write this it will be deleted before I even could press send button.

Hi there!

@Grisu – kindly ask you to clarify : are below mentioned valid for rt-ax86u or not? and what will be after reboot? or may be you know other tricks to change region settings in brоаdсоm cpu routers? tnx n advacne

nvram set asuscfe0:ccode=#a
nvram set asuscfe1:ccode=#a
nvram set asuscfe0:regrev=0
nvram set asuscfe1:regrev=0
nvram set asuscfecommit=1

I think you can forget all of these commands, AFAIK they are working only on RT-AC68U platform.

Sold all of my Asus routers 2 years ago, so not up to date anymore, but changes became more an more restrictiv so not to suppose they will change their minds now or in future.

I know that it is possible to do via ssh on any broadcom routers but can not find any details – look like top secret information ))
