How to increase download speed?

Hello,

There is a problem in network download content from the Internet in a while fix for example 200-250 MB of the file happens quickly, but it is rare, it often happens that the download speed does not exceed 80 -100 KB/S and no matter by wifi or wire.Network diagram

The bandwidth is low, even at the moment of downloading of the file nor the local interface any wan interface
The speed of browsing the pages is good, I would say excellent, YouTube videos loaded fine,without delay but the download file is just disgusting , don't know where to look , please help.

If you directly connect provider into the laptop , the speed is good, downloading files quickly, everybody..... here it is with the device network

Download interface you download the file 120 MB

Maybe the problem is not you, but on the server from which you download the file?
If I could, but not can fix almost all the data to go so long Mp3 song sway quickly, but the volume is not that big. - Amina62 commented on July 2nd 19 at 18:04

: from the house to try the helpless, a very small probability that omarsdottir on the same server and at work. - logan66 commented on July 2nd 19 at 18:10

All diagnosis should be carried out in the time of the problem. If it is possible to cause artificially( i.e., for example, the deceleration required to appear in one of 10 files ), that is already half of the case can be made say.
As soon as the problem arose.
1) Check the load on the ports
2) Trying to create extra load, look did( you can enable 4K on youtube on another computer in the same vlan )
3) Try to create the load from the other vlan.
4) If the channel utilization with increasing load increasing load successfully "scales", then try to download a file of similar format from a different server( at the time of the problem ) in the same vlan.( file format may affect the operation of anti-virus )
5) Repeat step 4 on the computer that has the problem( right now ).

If all 5 points show normal operation, then the problem is in the connection between you and the server( including the problem may be with the server itself ).
In any case, this will allow you to cut off a bunch of options.
Tried loading the channel by downloading the file to 120 MB, the download interface on the router was 10 Mbps , the file downloaded fast.but after a time , somewhere after 4 minutes, tried again download the same file from the same server. but the speed on the interface was 1388 kBit /s and the browser download speed shows 90 kbit/s. Why the stress on the interface of the router is low, if there was a load on the interface is high and downloading speed is low then the problem is in the Internet channel, but here the interface itself barely gives out speed. - Amina62 commented on July 2nd 19 at 18:06
Your method does not allow to separate the problem in different parts of the communication channel. According to your diagnosis, it could be a server problem, a problem on the path between your port and server port, the problem Mikrotik, the problem settings Mikrotik, the problem between microtia and the client, for example in the switches, Yes even the problem of packet loss due to bad compressed forks. - Amina62 commented on July 2nd 19 at 18:09

: then, or curve a balancer or packet loss. - Amina62 commented on July 2nd 19 at 18:15

Well run on some external server in the Internet iperf. Check mode udp, tcp. The scheme is too trivial. You might be jamb only to tcp and the problem in some mss, and may curve in balancing between providers. And maybe a joint and on udp and tcp, then you have to look at the problem on a lower level - on the IP, then corny can loss and excessive fragmentation, and maybe even the router perezagruzite on the CPU for small packets.

maybe Yes, there is much that can be... Run iperf on an external server and smoke output. bwping Monte yet to try, but iperf safer
