Why is the network on Mikrotik unstable?

Question

Computer networks

Router model RB951G-2HnD (mipsbe)
Internet from local RTK.
Mikrotik distributes Wi-Fi, and the Internet through the bridge. Wires are connected to the Mikrotik through two ports - one from the rtk switch, the second leads to a simple router, which is already distributing to other routers.
When testing through speedtest.net/ru, the connection breaks after the start, or does not start. It rarely runs completely, but at a reduced 1/4 speed, and even more rarely at the maximum (20 megabits) speed.
The drop in speed and disconnection applies to the local network too.

Answer 1

The question is formulated at the level of a housewife. So is your local network built on Mikrotik slowing down, or is the Internet provider being naughty? To begin with, I recommend checking the speed on the local network or plug the Internet cable directly into the pitch to cut off at least half of the problems.

Answer 2

1. Turn on the DHCP server and DHCP client (if the provider distributes DHCP settings) on the Mikrotik.
2. Distribute the Internet through routing (and not through a bridge).
3. Configure the shaper/QoS (so that the entire channel is not clogged with competitive requests)
4. Check the resource consumption on the router during intensive networking.

Answer 3

Check if PPTP is up to your ISP? If so, make sure that the Tcp fix mss option is set in the connection profile.

Answer 4

Firstly, google about setting up! Based on the fact that you didn’t provide information from the built-in test utilities, you don’t understand what kind of hardware you work with. Secondly, close port 53 on both protocols, by default any microt works as a dns server and is shared with everyone who wishes. Microts also have a very fastidious wi-fi, there are a lot of manuls, but sometimes they don’t work and the speed is scanty.
