Never seen this before in the system log???

OK, SSH was enabled and for sure a left-over from Merlin firmware.

I couldn´t disable SSH from the administration page so I cleared nvram with Putty and mtd-erase2 nvram.

Started from scratch and it seems this was a SSH bombardment mostly from chinese IP-adresses.

Going to enable ddns later and check system log again....

EDIT AiProtection enabled again.

In my case most ips were from China . 3 weeks ago i got a login attempt from California [emoji38] . Expect to see these logs again and again with ddns enabled

OK, but I have not seen this "bombardment" before, maybe these events are suppressed with Merlin or John's firmware?? Or something else is changed??

Also got the time settings error within the admin page but it was just to change to Greenwich time and then back to my timezone as other users already found out.

Asus recently added SSH support in the stock firmware. Unfortunately, two problems:

- It's exposed to WAN by default, with no way to limit it to LAN
- The System page is currently borked, you cannot change any setting on that page due to a Javascript error caused by a bug in their new DST handling code

My SSH implementation does not expose SSH to WAN, unless you specifically enable that option.
 
Ok, great answers!

I also enabled ddns and no problem with that within the system log.

It must be a ugly SSH solution from ASUS...... never seen such bombardment!
 
Is huawei e3276 allready working with this firmware or anyother merlin firmware? I am still using 374.XX...

Nope, max 20 Mbits (cdc_ncm high speed driver not used), I gave up and using a Dovado Tiny as bridge.....

I have also signed a fiber contract and they will dig as soon the snow is gone.

EDIT .3873 works just fine nevertheless after my nvram-reset yesterday!

v3873 is running stable and fast here. Mad props to ASUS to finally get their act together after 1 year.

RT-AC68U is a fantastic router.

Sankel1 do you mean Version 3.0.0.4.378.3885? There is no 3873 that I can find......Do you have a link?
Please clarify

Ever since upgrading from 3.0.0.4.376.3626 to 3.0.0.4.378.3873, port forwarding on my RT-AC68U stops working nearly every day. It has to be disabled and re-enabled. Reboot times are over 2 minutes. Also, previous firmware versions allowed separate MAC filter rules per band, but this no longer appears to be the case.

From the lack of posts, these issues don't appear to be common. Any help would be greatly appreciated!

I had similar problems with my guest network that no one else had.

My only advice would be to start completely refresh, so run: "mtd-erase2 nvram" and then hold down reset for 5 seconds.
 
Do reboots typically take 2 to 2.5 minutes?

Was the ability to configure the wireless MAC filtering per band removed in 3.0.0.4.378.3873?

Yes, varying based on which services you have enabled.

Yes. Don't know why, but it was deliberate and not a bug, considering the code that was added to achieve this.
 
That's a disappointing reduction in functionality. I've always preferred a single SSID, and per-band MAC filtering allowed me to better manage my wireless clients. Is there a resource at ASUS for feedback on changes like this?
 
I just installed this firmware and did a factory reset (3.0.0.4.378.3873). Has anyone checked the GUI on.... Network Map>System Status>Status Tab. my CPU and RAM does not display its current state. it just displays "NAN%".

update: GUI works fine with chrome. has errors when using IE.
Yes, I have this problem and I use IE11.

NaN is an abbreviation for "Not a Number" and is sometimes used when an invalid value is returned for a field.

It's beginning to look like ASUS makes a few changes and then puts a release out for field testing to find the bugs. The only problem is the bugs are multiplying. :mad:

It seems that Merlin :) is doing a far better job than ASUS despite what must be much more limited resources.
 
After installing 3.0.0.4.378.3873 I have frequent disconnects

The router runs (sometimes hours, once one whole day) but then restarts itself with a new date in the logging (always Dec 1), here an example of the logging:

Jan 25 00:59:57 ntp: start NTP update
Jan 25 01:59:59 ntp: start NTP update

etc

After the firmware update I reset the router as instructed and did a factory reset through the UI.

I also needed to set the region to GMT to be able to set a new user name and password.

After a manual power cycle the router works again ..... for a period.

Is this a firmware problem? Any clues?
