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.

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.

Update:

Just discovered TIME has different method to login after one accidentally update the nightmare firmware which hide the firmware upgrade page.

http://192.168.0.1/userRpm/firmwareUpgrade.htm

Except that one is for US hardware and not EU hardware.

Firmware is same as US beta firmware.

According to sohlican, he can access the hidden firmware page via the link after updating to TIME firmware.

Only applicable for v60000 firmware.

Older 30000 and 40000 firmwares which TIME firmware seem to be based don't make use of the extra 13 digits.

Eh? You mean TIME already use v60000 as base firmware?

Well, I did posted how to find the 13digits on post #15.......

-.- Devices not added to QOS list will get lowest priority. Didn't you read the manual?

After click connect, still cannot online?

Go call TM again and ask for username and password.
Password is case-sensitive.
Starting to think you enter the wrong username as well.

Triple check again.
Wrong login/pass issue.

Meanwhile, please check

Don't.
This is clearly a case of wrong unifi username/pass.
Use TM Live Chat service to reset your password again.
At unifi.com.my , you can find your login username too. (check it just to be sure)

To answer wifi missing channels and signal issue:
1) Archer C1200(EU)_V1_170706 C1200v1_eu-up-1.1.1 Build 20170706 rel.65715.bin as well as beta firmware C1200v1_eu-up-1.1.1 Build 20180101 rel.66049(Beta)
are missing wireless.region.json, wireless.24g.json and wireless.5g.json. Meanwhile C1200v1_eu_tm-up-boot-1.0.0 Build 20170905 rel.41738_2017-09-05_13.51.02.bin has those three included. Since I am the only one who complain about wifi channels issue to TP-Link about these missing files, I guess they ignored me?

2) TX beamforming = For C1200 case, it only has Single-User beamforming mode (only 2 antennas are used for 5ghz, don't get confused with 3 antenna. The middle antenna is shared between 2.4ghz and 5ghz), therefore if one 5ghz user is heavily downloading stuff, then other 5ghz users will get lower signal strength in dB. Of course CPU usage gonna increase because calculation needed for beamforming. With SU-Beamforming, it is generally accepted the signal strengh will be improved up to 5 or 8 dB.

3) Wifi link speed going up and down? Did you align three antennas correctly? (In front of router looking at LED, left=5ghz, middle = 2.4ghz and 5ghz, right= 2.4ghz). Don't forget TP-Link also turning on wifi power saving by default, meaning if there is no wireless activity, the link speed will be reduced. (Not to mention if 5ghz beamforming is turned on and one user is downloading heavily scenario)


EDIT:
Here a funny part, in v40000 series TM firmware....do you know it defaults to Bahamas wifi region?


Then, remote management TR-069 is enabled by default and can't be disabled. A security risk indeed.

Now then....here another funny and legal parts.

According to Portal Rasmi Kementerian Komunikasi & Multimedia Malaysia, http://www.kkmm.gov.my/akta_kpkk/WiFi%20Gu...e-Final%20V.pdf , year 2005 ;



The latest one from MCMC as shown below, https://www.mcmc.gov.my/skmmgovmy/media/Gen...WirelessLAN.pdf , finalized in year 2013 has funny typo....
Example:



5150Mhz? Not sure if compared to year 2005 document and the year 2013 document itself where the appendix section mentioned 5250Mhz itself, see below:

But ETSI EN 301 893 documentation mentioned 5150 to 5350 exists....oh well

......let get started with 5150 MHz to 5350 MHz, 5470 MHz to 5650 MHz and 5725 MHz to 5875 MHz.
https://www.mcmc.gov.my/skmmgovmy/media/Gen...C-T007_2014.pdf

The data above shown DFS is mandatory for 5150 MHz to 5350 MHz.
DFS and TPC is mandatory for 5470 MHz to 5650 MHz.
Meanwhile DFS and TPC are not needed for 5725 MHz to 5875 MHz.

Based on legendary wikipedia information https://en.wikipedia.org/wiki/List_of_WLAN_...2.11a/h/j/n/ac)
At 5ghz...the approved channels (in this case 20 Mhz bandwidth) for Malaysia are channels
36, 40, 44, 48, 52 ,56, 60, 64 = 5150 MHz to 5350 MHz
100, 104, 108, 112, 116, 120, 124, 128 = 5470 MHz to 5650 MHz (132, 136 and 140 are forbidden by MCMC)
149, 153, 157, 161, 165 = 5725 MHz to 5875 MHz (Technically, Malaysia can use 147, 169 and 173, however tplink c1200 hardware is designed for use in EU, so it is unlikely EU hardware revision can support these three channels)

Checking the EU V1 beta firmware......

Country code DE = Deutschland, Germany. But according to German regulation....it should support :

36, 40, 44, 48
52, 56, 60, 64
104, 108, 112, 116, 120, 124, 128, 132, 140

Weird....I wonder where is the function to select wireless region.....

Oh great...it is hidden and 'unselectable'


Life sucks.


Hmm...Malaysia is there....

Any idea?

Nope, I can't do that. Random reboot is my worst enemy.
Currently I am trying to see if one can set the wifi region using the beta firmware.
The code sure hella long....

The good news on C1200 EU V1 hardware support :




The really bad news :

It is locked out by firmware.

Anyone wanna complain to TP-Link? I tried....no result...

Just a quick check. Did you fully reset the router after updating the firmware? As in pressing the tiny reset hole? There are few reports about settings aren't properly saved after updating from v40000 to v60000. A hard factory reset is needed instead of soft factory reset.

WDS Bridging is hidden as well. Geez....if all these functions are enabled, it would be a killer router.

The main problem = I don't think they will unlock the wifi region selection if one takes a look at Archer C1200(EU)_V1_170706 firmware.

Well....I am out of idea in solving your issue.


Meanwhile, I was able to enter the region selection, however, it can't save the settings.
