The connection between the two routers in a wireless bridge mode disappears

Good evening. The problem I have is this. There is a video surveillance system, which should be connected to the Internet for remote viewing. The system itself with a router that looks in the direction of the Internet wire to connect is not possible (features of the room, repair, etc.) It was decided. I took a router TP-Link TL-WR740N as a client connected it to the access point zte. On TP-Link IP static, on zte too, all in the same subnet. Internet started working on TP-Link, everything is fine. In the DVR status online, remote works. To test it, I turned off the power several times, everything picked up and continued to work.

A few days pass, the connection disappears. Reasons are unclear, I am in another city. Then after some time (a day or a few days) it starts working again. And so it drops out from time to time.

Question: how to solve the problem. It has not worked for a long time, a week exactly. Can you tell me what equipment to put to keep the connection ironclad, or in the settings to change something. Thank you in advance.

Answer

Good evening. I’m not sure that I understood the connection scheme correctly. Is the DVR connected to TP-Link TL-WR740N, which in its turn is connected to ZTE in wireless bridge mode (WDS)?

Frankly speaking, such a scheme with wireless bridge has nothing to do with video surveillance. Especially with TP-Link TL-WR740N. This is a budget, weak router. Maybe it just gets warm or something else and hangs or reboots. You need to connect the DVR to the router by cable. Be sure to run a cable during the repair process. If you have set up a wireless bridge between two routers, the distance there is probably not very long.

Not the fact, of course, that some more productive and expensive router will work stably. A wireless bridge is not a very stable thing, especially with such equipment. And I understand that you are not sure that the reason is TL-WR740N. Maybe it’s ZTE that disconnects, loses connection with the provider. We need to find the culprit first.

You wrote that TP-Link has a static IP. How and why? Try to disable DHCP-server on TP-Link. Configure according to the instructions: Configuring a Tp-Link router in bridge mode (WDS).
