Hi Asus,

It's the same issue again. Even after downgraded software, the RT-N12 D1 as repeated only worked for one day only and next day same issue again.

Hi ASUS technical Support

Router: Wireless AC-1200 Dual Band
Recently updated to firmware Version:3.0.0.4.382_18991

I am using this router + an 8 port switch for my office network.
Recently we have been experiencing frequent disconnections within our office network. Which happens once or twice everyweek, and each time this happens we are disconnected for roughly 5 minutes and then it gets back to normal.

For most applications, the error we got was "ERR_CONNECTION_TIMED_OUT"
CCTV network, Google Chrome (when not connected to internet), Microsoft Outlook

Please advise

Thank you.

The model you have is not fit to be used in a demanding office environment. I afraid you need some better routers for that kind of purpose.

Get an enterprise router if you are in an office environment, something more powerful with stronger processor.

as others mentioned, get a powerful router such as AC68U or above

Hi guys

thanks for your prompt feedback!

Any idea what is the root cause of the problem, how do I get a proper diagnosis to make sure that my router is not good enough for my office environment?

Additionally, this problem only started recently (a few months ago).
Bought the router August 2016, after using about 1 year plus only experience such issue.

On a side note, would be great to hear from ASUS technical support team as well

Hi chuyeu,

If you not looking for feature like fail-over or load balance, then RT-AC1200G+ are able to suite what you need.

Thank you

Hi HuorEarfalas,

We tested the beta firmware are usable on UNIFI, as for the Maxis Fibre, we are still testing it. Hopefully can get the official firmware done ASAP.

Thank you

Hi krofal,

Can you try sending the RT-N12 D1 for warranty claim?

Thank you

Hi toobad,

Does this problem occur after the firmware update? Can you try do a factory reset on the router and try again?

If the problem still persist, can you share us the system log from the router?

Thank you

For starters, it would help if you provided the actual router & switch model info vs "Wireless AC-1200 Dual Band + 8 port switch"..

Bro I think he meant the Asus RT-AC1200G+ or this model: https://www.asus.com/my/Networking/RT-AC1200G-plus/

Hi Asus MY
IT is all Asus router RT-AC1300UHP,RT-AC-58U,RT-AC1200G+,RT-N18U, all can support IPTV from TM STB Box?
I ask TM there say STB use different VLAN to play there are no lagging on IPTV,but when i download use fullspeed
the screen will become lag,my own router is RT-N12D1,maybe will change the router the selected

Got a question is IGMP Proxy and IGMP Snooping want to open when use the IPTV function?

Ahh I see.. Then previous advice still apply.

i hv used rt ac1300uhp and rtn12hp_b1.

both pulg n play for hypptv stb, lan port#4.

the bandwidth for hypptv is separate from the other.

download full speed does not affect stb at all.

if u get lag with hypptv, it may be due to yr stb failing or a localized unifi problem.

But my STB is new,i want know is it my own router cant handler my download and STB on same time because when i use 30mb donwload full speed the cpu usage become 85-100% ald and the STB will become lagging

new stb can be problematic too... i have read comments the video "jerks" from time to time.

and did u ever try to muck around with that box to sideload 3rd party apps on it?

i am using the old silver one, all good.


your rtn12 cannot be so different from mine.

mine handled 50mbps no sweat, hypptv stb is fine.

u may want to check firmware, see if asusmy can comment.

I found AC58U got some promo price at a shop and I go for this model.
Very good. Meet my requirement.

how much u bot?

Anybody has their asus routers set on scheduled reboot?

I used to set my AC68U to reboot 3 times a week, and after rebooting both my 2.4/5 GHZ wifi will go haywire and all my devices wont be able to reconnect. Have to manually restart most of the time. Hence I reduced mine to twice a week, and still the same issue. Any idea on what's wrong? I have home automation which relies on the internet connection so it's really troublesome to wake up finding that they are not working due to the router.
