Running my server impairs traffic on the network

I've setup an old laptop with linux mint running jellyfin and arr stack in docker containers.

When I run it the Internet in other devices in the network becomes virtually unusable after about 10 mins of the containers having run.

I don't really know what to do, so I wanted to ask for advice.

If you’re not using a VPN, it’s possible your ISP is throttling your connection when it sees p2p traffic. Just another thing to look into.
- seems to be the case, thank you. It seems obvious, but I wouldn't have thought about it without your comment
Do you have a 15mb DSL connection or something? If it’s close to 100mb or more you should be fine on this front. Maybe your router is super old and cant handle lots of connections that the arr stack requires. You can limit the amount of parallel connections and the total bandwidth available to the arr stack.
As for Jellyfin, if the problem is your slow connection to the outside internet, then you can force transcode all streams to non local clients to a lower bitrate, but direct stream to local clients (assuming your router can handle that, but I’ve never seen a piece of networking equipment that is slower that 100mbs)
Also I’d recommend connecting to your router’s web gui and see what it says, how mush traffic is going around and so on. You can usually find your router’s ip and login details on a sticker on the back.
- I have about 100mb. My router is huawei b535-232. I went over all the tabs 3 times and haven't been able to find any bandwidth limiting options nor info on the traffic.
If this is all happening wirelessly, that could be your problem. Looks like you have a 4g modem with a built in router. Is anything in the aar stack connected to the router through Ethernet, or is everything using WiFi? Try hooking the laptop up to one of the lan ports on the back of your router, see if that helps things.
Could also just be all the aar apps doing their thing for the first time, pulling from databases, downloading cover art, etc. once your library is all set up, they should calm down. Only way to really check this is to log into your router and see who the loudest talker is.
- the laptop with the arr stack is connected over ethernet
Does your router have webinterface where you can monitor and potentially limit network usage of devices?
I'm not too familiar with the arr stack but if it is constantly downloading videos it's probably using full bandwidth. Maybe you can also limit in the arr settings or throttle the network interface on the laptop.
- I'm using huawei b535-232 ans I haven't been able to find such panel on the Web interface.
  
  If you're using QBittorrent, you can throttle upload/download speeds in the settings. I believe it wants speeds set in kibibytes (KiB) so you'll need to convert your megabit internet speeds to your desired kibibyte limit (say maybe 50% or less of your available bandwidth).
What, exactly, are you running? What is it doing?
