There are several versions of Archer C7. What version is yours?
You can find the version number on a sticker at the bottom of the router.

Which firmware are you on now?

Try the latest firmware: http://www.tp-link.com.my/support/download...r+C7&version=V2

I'm not sure if this firmware supports Maxis Fibre & UniFi or not, you'll just have to try.
If nothing works, you might want to try OpenWRT.

sorry to bump old thread. did you manage to fix this issue as I have experienced the same thing?

so that means you haven't used the c7 as connected directly to BTU? planning to send this back to their service center  but not sure if they will be able to fix the issue.

anyone managed to get this fix? I still cant

at least this thread is still active for live discussion. I bought 1 yesterday without knowing that it is having problem with Maxis... In a very stressful state at the moment... How i wish My AC68U is back from taiwan...

im trying to use for my Maxis fibre at home, it received the IP and server from maxis, but it is not receiving any packets...

i brick the C7 but unfortunately cant understand a single thing it said in this bricked version. OPENWRT... now i am trying to recover it back to factory.. seems impossible.

Managed to get it to work with my maxis fibre, except that now phone is not working. Until my ac68u comes back from taiwan, this will suffice.

u cannot use the latest one downloadable or the original one if your unit says it is compatible with maxis or unifi. It doesn't work.
I had to TFTP mine, change my pc ip to 192.168.1.66 and use the Archer C7 V2 firmware international one.

Then from there, you enter your PPPOE info then you must make changes to your VLAN.

Any senior ppl here to guide me how to setup the wireless router Archer C7 V2?

noob here.

i source around the web and those info i tried seems not working or maybe my understanding not clear.

i'm using maxis fiber.

the strange thing is WAN there didnt show any IP add.... all in 0.0.0.0

I had successfully setup my TP-LINK Archer C7 v2 to connect Maxis Home Fibre by using OpenWRT Chaos Calmer 15.05-rc1 (now rc2 released) firmware.

The TP-LINK official firmware is lousy.

First of all you need to flash OpenWRT firmware.
http://downloads.openwrt.org/chaos_calmer/...hfs-factory.bin
Step 1: Flashing the firmware.
You shoud have this. (picture from TP-Link site)

Just browse to the OpenWRT firmware file you downloaded just now.
Then upgrade, you should good to go.
Step 2: Login to OpenWRT. Initially is 192.168.1.1 (no password for 1st time until you set it after that)
[attachmentid=4494079]
Step 3: Goto "Network" -> "Switch"
[attachmentid=4494080]
Step 4: Setting the VLAN ID
Port1 = WAN Port
Port2~5 = LAN Port 1~4
Port6 = WAN for IPv6
[attachmentid=4494083]
Should look like this.
"Tagged" Internet VLAN 621 on Port1&6
"Tagged" VOIP VLAN 821 & 822 on Port(2)or(3)or(4)or(5) depend which Archer C7 LAN port connect to your Maxis Router(Technicolor TG784n v3) and Port6(must)
"Tagged" IPTV Astro VLAN 823 on Port(2)or(3)or(4)or(5) and Port6  if you need the IPTV service
Save & Apply

Step 5: Goto "Network" -> "Interface"
[attachmentid=4493954]
Step 6: Setup your WAN, "WAN" -> Edit
[attachmentid=4493962]

{General Settings}
Login info should be like this.
UserID@home.maxis.com.my (if you do not change to public)
UserID@public.maxis.com.my (if you change to public)
Password: UserID+1
[attachmentid=4493974]

{Physical Settings}
Select the VLAN Interface: "eth0.621" (wan)
[attachmentid=4493979]
Save & Apply
It is ready to connect your Maxis Home Fibre.
I would skip the WiFi setup, I think you all should know how to do.
But kindly inform, you can only stable in WiFi-bgn 2.4Ghz since the 5Ghz AC WiFi LINUX mod-driver in OpenWRT not quite compatible, though it is working, but it would only show up 6mbit/s in bitrate, speed performance I didn't test. Sometimes it may confuse the 2.5Ghz WiFi. so it is good to disable the 5Ghz AC WiFi if you are not using.
Then Below is setting up the Maxis Thomson Technicolor TG784n v3 Router.
Connect with your PC LAN cable to Maxis rounter LAN port (or Maxis WiFi should do so).

Login to Maxis Thomson Technicolor TG784n v3 Router.
http://192.168.1.254

Step 1: Click on "Advance Configuration"
[attachmentid=4493992]
Step 2:
"Maxis Gateway" -> Setup my Maxis Gateway
[attachmentid=4493995]
Next
[attachmentid=4493996]
Use the "Bridged HSI(GPON) + VOIP" rather than "Home HSI(GPON) + VOIP"
[attachmentid=4494002]
Then Next
Use "TM" if you are under TM infrastructure or else Maxis if you are Maxis Infrastructure
[attachmentid=4494003]
Then Next
Enter your VOIP phone number in URI & username. eg: 0312345678
password:  phonenumber+1
[attachmentid=4494004]
Then Next
Then "Start"
[attachmentid=4494006]
It would restart your Maxis Router.
[attachmentid=4494007]
Then Finish
[attachmentid=4494010]
Step 3: Disable Maxis WiFi
You do not need the Maxis WiFi anymore.
[attachmentid=4494031]
When you click "Disable", it may sometimes not working.

Goto "Advance Configuration" -> "Home Network"
Click on the WiFi.
[attachmentid=4494032]

Then {Configure}
[attachmentid=4494033]

Untick all these box.
[attachmentid=4494040]
It is all done now.
But be reminded, if you restart Maxis Router anytime, its WiFi will automatically active back. So you need to disable it again.
The LAN Cable on Maxis Router WAN port connect to TP-LINK LAN(?) port which the port set VLAN 821/822 for VOIP.

Arrangement like this
[attachmentid=4494077]
Now your Maxis Router become a just VOIP phone unit, no WiFi and other use.

If your VOIP works, your Maxis Telephony should be like this, it is registered.
"Toolbox" -> "Telephony" -> "Detail"
[attachmentid=4494051]

If not, try re-configure the Telephony.
-> "Configure"
[attachmentid=4494054]

[attachmentid=4494066]
If you still cannot make the Telephony Registered, it means you need to call up Maxis Service Centre. They need to reset your Telephony password, which sometimes Maxis himself will ruin their server settings.
Hope this helpful and good to go.
TP-LINK Archer C7 v2 won't brick, once you spoiled, just connect your LAN cable to LAN port1 and set your PC IP 192.168.1.66, use a TFTP software (http://sourceforge.net/projects/tftp-server/) download and install, put the firmware file under the software folder in ArcherC7v2_tp_recovery.bin filename, then it would re-upload the firmware.
Both TP-LINK official and OpenWRT firmwares will work.
By the end, we all know Maxis Router is a crap, you can replace it with other VOIP Adapter.
Of course the adapter settings would dependent . You just need the SIP phone number, username & password, that's all.
