Hardware Version: V1
Firmware Version: 1.2.0 0.9.1 v0001.0 Build 200511 Rel.44954n

This is how my setup is:


I have a local broadband for which they provided a modem Syrotech model

I connected the modem to TP Link router Archer C1200 v2.0 

Firmware version: 2.0.2 Build 20180118 rel.38979 (EU)

The broadband connection type is PPPoE which is configured in Archer C1200 v2.0

Other settings of Archer C1200 v2.0

IP Address used:

IP Address pool: to

Default Gateway:

DHCP Enabled: Checked.


Archer MR600 4G Router configuration: 

Now I connected Archer MR600 in a different room through an ethernet cable to Archer C1200 v2.0

Archer C1200 v2.0 LAN to Archer MR600 WAN/LAN port.

Archer MR600 Operation Mode is: Wireless Router Mode

The internet works fine and I have inserted a sim that works fine. 
Sometimes when my WAN connection goes down the router doesn't failover to my 4G network

Other settings of Archer MR600 4G Router

IP Address:

IP Address Pool: to

Default Gateway:

DHCP : Checked


when I check internet status on the router it shows the below message:
Please reconfigure your parameters. If problem still exists, Please contact your ISP.
If I go to settings and disconnect WAN/Internet then 4G connection starts working, but auto failover is not working.



I sent multiple emails to TPlink support no one is responding, please help.

Hi, I think the problem with the failure lies in the fact that on the MR600 you have not configured the pppoe. MR600, in my opinion, cannot detect a problem on the ADSL line. I have the same problem, I activated the pppoe relay on the router of the ISP and the MR600 seems to be trying to failover. Now I have 4g problem, but that's another problem .....
