The WDS connection between the TP-Link routers disappears and there is no access to the settings
Answer
Hello. Of course, it would be good to solve the problem with connection drops between routers in WDS bridge mode.
True, it will be very difficult to find the cause of these connection failures. Especially since you have such a long distance network through a directional Wi-Fi antenna. Maybe it’s because of a weak TP-Link TL-WR720N router, maybe some interference, failures on the main router, etc. You can experiment. Configure the network on a different channel (have you set the same channels on both routers?), change other Wi-Fi network settings.
As for the problem with entering the settings of TP-Link TL-WR720N router, which is configured in bridge mode. Didn’t you change the IP address on it? I just don’t understand why you’re getting into the remote router settings, since they should have different IP addresses. And if even TP-Link settings aren’t available, it would just pop up an error.
As an option, in the settings of the remote router (if you have access to it) in the list of clients DHCP-server to find the second router (if it does not fall off, but just the Internet disappears) and go to it.
And after a normal reset, doesn’t connection with the remote router on TL-WR720N restore? Do I have to do a reset and configure the bridge again?
