Model: TL-MR6400  
Hardware Version: V4
Firmware Version: 1.7.0 0.9.1 v0001.0 Build 181214 Rel.49556n

Hi everybody,

 

My Internet left many times per day on my TL-MR6400 v4, just bought....

 

When the problem happened, all lights of the modem are on.

 

I saw many users have same problem with different models of 4G modem. I saw answers given by tp-link staff.

 

So I create a manual apn profile, set manual dns servers on dhcp menu (8.8.8.8 and 8.8.4.4), check 4G connection with my phone but the problem is persistent.

 

 

Nothing appears in the system log, all steps indicate "pass" in diagnostic menu...


 

 

So I need to reboot the modem and it works again. So please help

Hi all,

 

If you have the disconnection issue with your router, please provide the information mentioned below so that we can speed up the whole process and offer a solution. 

 

1. Please give us a brief introduction to the current issue; what kind of troubleshooting you have done and what about the corresponding results. 

 

2. What is the model number of your device? And its hardware and firmware version. 

Note: Please ensure that its firmware is already up-to-date. 

 

3. Please check the country version of your router as well. It is printed on the bottom label of the actual device, next to the model number.

 

4. You can try to create the network profile manually or update the ISP profile. 

https://www.tp-link.com/support/faq/1663/ 

 

5. Please keep an eye on the Band info (Advanced-Status page) when the network is working fine and when it is not, whether there is a difference.

 

Thanks for your support and cooperation in advance. Have a nice day.

Hi, you can find the beta firmware to select the band manually on the MR6400 here:

https://community.tp-link.com/en/home/forum/topic/241534

 

Note: Be sure you are installing the correct firmware for your hardware, you can verify that by checking the router bottom label, which will display a V4 or V5.

Some news for you Kevin,

 

I just have the problem so I've tested to ping some interesting IP before reboot the modem

 

IP of the TL-MR6400 alias 192.168.1.1 : it's work

IP of my all my local network devices connected via wifi or wire (192.168.1.X) : it's work

 

IP of the primary dns notified in status (192.168.10.110): it's work

IP of dns notified in the dhcp settings menu ( 8.8.8.8 and 8.8.4.4 ) : it's work

 

All other IP or name of website don't work .....

 

tested with ping google.com or ping 193.252.19.3 and 80.10.246.2 ( dns servers of french orange provider )

 


 

If it can help you !

Don't forget to send me the beta firmware please
