Is the speed of Internet access significantly reduced when watching video from a Wi-Fi IP camera?

Question

WiFi

There is a TP-Link TL-WR1043ND router and a JPT3815W IP camera connected to the router via Wi-Fi. The PC is also connected to the router via Wi-Fi.
When watching video from the camera, the connection speed drops very much: from 70 / 60 Mbps to 30 / 8 Mbps (Download / Upload, respectively).
An hour of uncompressed video from a camera is approximately 450 MB. Why does the speed drop so much and is it possible to solve the problem?

Answer 1

This usually happens when viewing iptv through a router - the latter simply cannot cope with a large number of udp packets (it’s not for nothing that they most often use udp traffic).

Answer 2

The video is transmitted in a large number of small packets.
I admit that your router corny rests on the ceiling of packet performance.
The media access method is still CSMA/CA.
This means that very often your laptop and camera simply cannot agree and will wait for a neighbor.
Since the camera broadcasts more often, the laptop will always expect a little more. Accordingly, this will lead to a loss of bandwidth for the laptop.

Answer 3

Probably wifi jumps between b,g and n modes and spends a lot of time on it. Try to explicitly "clamp" g mode in the router and see what happens. And play with ranges.
