WARNING
If the router is flashed with EU firmware, one WILL NOT BE ABLE TO FLASH BACK to TP-LINK TM Malaysia Firmware.
As requested by imalmighty, one may wish to flash back to TM or TIME firmware after updating to EU firmware.
First, download and upgrade to the EU firmware at EDIT7 below, then flash TM or TIME firmware at EDIT6 below.
Note that every settings will be reset.
However, sometimes these steps result in corrupted config.bin after upgrading and the router is not able to boot or run correctly.
The solution is to take a pointy stick and press 'reset' button to restore the config.bin back to normal.

Please note EU firmware only contains wifi 5Ghz channel 36, 40, 44, 48 while Malaysia firmware contains channel 36, 40, 44, 48, 100, 120, 161 and 165.
EU firmware = 5Ghz beamforming and AP Mode available
MY firmware = No 5Ghz beamforming and no AP Mode.

Note : After flashing firmware at EDIT7, one can flash US firmware to the router, see EDIT10 below.



EDIT: For those who accidentally updated to TIME Firmware that hides the firmware upgrade interface, please login and enter this address http://192.168.0.1/userRpm/firmwareUpgrade.htm or follow the instruction posted by biloxee here

EDIT2: As pointed by RoxyGal, official firmware for C1200 V1 (EU) is out.
TP-Link site : http://test.tp-link.com/en/download/Archer...1.html#Firmware
Direct link to firmware : http://static.tp-link.com/2018/201801/2018...)_V1_180124.zip


EDIT3: Since the official firmware and previous beta firmware only have channel 36, 40, 44 and 48 for 5Ghz wifi at 200mW......plus few are complaining about not being able to use channel 161 and 165 at 1W..... here is the beta firmware for TM which supposely fix the random reboot issue. Do note TM beta firmware has TR-069 enabled by default as well as additional @unifi suffix at wifi.

EDIT4: Official TM Firmware is out at https://www.tp-link.com/my/download/Archer-...1.html#Firmware Direct Link : Archer C1200(EU) V1 TM Unifi Wireless Router (Latest 15-2-2018)


EDIT5: New beta firmware C1200v1_eu-up-1.1.3 Build 20180308 rel.49551(Beta) is out. http://support.tp-link.com/f/a65fe63a04/?dl=1 ---->EU version. This is not Malaysia version.

EDIT6:
Due to TP-Link Malaysia website inconsistency....better visit tplink Malaysia official site itself for TM and TIME firmware version

C1200v1_eu_tm-up-1.0.0 Build 20180403 rel.22124_2018-04-03_14.13.08
C1200v1_eu_time-up-boot-1.0.0 Build 20180502 rel.45702
EDIT7: C1200v1_eu-up-1.1.3 Build 20180502 rel.46288 (Link is dead, rehosted at zippyshare) is out ---->EU version. This is not Malaysia version. Thanks to zhuoyang, no idea where he/she got it from TP-Link forum Found the post here. Apparently, this one is supposed to fix UPNP not working issue.

EDIT8: Wireless distribution system (WDS) functionality can be enabled and it works (most of it), please visit page 29. Read all stuff at page 29 from top to bottom.

EDIT9: Apparently, a lot of users complained about WAN IP changing the next day. This was caused by AUTO selection at router PPPOE dialer. Seriously, I expect users to set On Demand when setting up the router from the beginning. (This should be common knowledge, no? Who in the world use Auto? ). Here the guide:


Do note the router with latest firmware still randomly reboot once every 3 - 4 weeks.......

EDIT10:
According to Aspick and heidarren, apparently after flashing EDIT7 EU beta firmware, the router can be flashed to US firmware available here https://www.tp-link.com/us/support/download...00/v1/#Firmware
The US firmware has higher transmit power (<30dBm) compared to EU/MY firmware (<23dBm) for 5ghz channel.
On the other hand, the US firmware seems to have lower 2.4ghz transmit power.
Warning : Unsure if the router can be flashed back to EU/MY firmware after flashing to US firmware. Once flashed to US firmware, there is no going back to EU/MY firmware.

My router just rebooted by its own today morning. Just realize my public ip changes from 175 to 202. Which means, I flash the router to beta on 4th January. today is 10th January. 6 days rocking solid.

may i know how to detect if router rebooted apart from ip changes?

got my unifi since 2/1/18 and this router c1200 quite okay so far

never aware any rebooted issue while i'm home

away from home sometimes i check my ip camera and so far okay

You can see the router log, apart from public ip change.

thank you. will see the log tonight.

if got rebooted a lot will consider to use beta firmware

This is my pov on the beta testing I did on my router. I've updated in my personal blog. You can read if you want.

thank you for sharing that article

will refer to it if i install the beta later.

How to install this new firmware if the update firmware page is hidden?

Do you flash your router to the latest version issued for time users?

I believe so, it was flashed by TIME technician when they were here earlier.

Any idea when will the BETA firmware be out as Official FW?

Then, you won't be able to flash your firmware as the newest firmware by Time hides the firmware upgrade page.

Too bad for me then, I'll probably sell the router off and get a better one.

i just install TIME yesterday..is this bad news for me too?

Hmmm....not sure about TIME firmware....but can you access through the link below after login?

192.168.0.1/webpages/pages/userrpm/firmwareUpgrade.XXXXXXXXXXXXX.html

Replace the xxxxxxxxxxxxxx with the 13 numbers that often accompanies the link when you mouse over any of the menu.

will give it a try later...

It is actually decent for daily use, if the firmware is fixed. However, since it isn’t, I would recommend you get a better router any way.

Nah, it is actually adequate for day to day use, only if the firmware is fixed.

so..wat happen if i dont fix the firmware??

Depending on your luck, you get random reboots, high CPU load, wireless connectivity loss, and so on. Some people are ok, and some are not.

Sounds terrible..

hopefully mine will be okay..
