TL-MR6400 IP address conflicts for wireless clients
Dear Sir, Madam,
I have recently purchased a TP-Link TL-MR6400 4G/3G router in order to get good quality Internet using cellular networks. I have bought a SIM (operator: Bouygues Telecom, France) and have managed to set-up the Internet connection. All the devices I connect to the TL-MR6400 using an Ethernet cable have access to the Internet.
Here is my situation with the Wireless devices (laptops, computers and smartphones):
- I can connect any of the devices to the TL-MR6400 Wi-Fi network but they do not have access to internet. The web browsers of my PCs come up with the error "IP address conflict".
- I can connect to another device which is on the TL-MR6400 Wi-Fi network without trouble. For example, I connect my PC to the Wi-Fi and then connect my Blackberry 10 to the Wi-Fi, and my PC will find the Blackberry 10 on the Wi-Fi and connect to it.
- I upgraded the TL-MR6400 with the latest firmware available in February 2020 and I still have the same problem.
To sum up, clients that have only been connected to the TL-MR6400 wirelessly do not have access to the Internet. This is particularly a problem for smartphone devices, as I cannot use the "connect them first by Ethernet" trick.
Maybe the TL-MR6400 is not setup properly ?
Any ideas how I can solve the problem ?
Best regards,
