Slow LAN transfer speed?

Question

network hardware

Friends asked to install video surveillance in the god-hammered village. Optical fiber, logically, is absent. I had to buy a miracle of Chinese technology - a 4g router with a lan port, I refused the USB modem to the registrar, because they liked the idea of ​​\u200b\u200bwi-fi. The problem is that the Internet works stably, and the application (partizan) barely loads one video channel and freezes, not to mention 4x. I thought it was a problem with the Internet, but when I connected to the registrar via local IP, I found exactly the same situation. I used the LAN cable that came with the router, there are really no Ethernet settings in the router. What to sin? We can hope that this is a low-quality cable connecting the router and the registrar, or is it still a router? Before that, the registrar had been working in another place for two days, everything was ok with remote work.

Answer 1

First free tip - don't buy garbage.
The second free tip is to write to technical support and update the firmware.

Answer 2

Have you tried connecting with this cable from the computer to the registrar, from the computer to the router?
