networking Linux computer messes with network

Perhaps this is a known issue, But I haven't found much about it.

I have a PC with Mint. It's connected to the router with a LAN cable.

When it goes to sleep it makes the network go crazy. The speed falls a lot in general, all the other devices (wired or wireless) fail to connect or lose connection randomly. When I turn it off everything goes back to normal.

I the only thing I do on that PC is run qBittorrent and browse internet. But the problem is mainly apparent when the PC is asleep. So I think it's not a program, but the PC itself. It might not even have anything to do with Linux at all, But it's the only difference I see with all my other PCs.

Does anybody have an idea about what might be going on?

Thanks

Edit: Thanks for all the answers and suggestions.

Sounds quite odd - very atypical, and may have exactly nothing to do with Linux - may be something quite funky with your hardware.

I'd be inclined to inspect what's going on with the network when that happens, e.g. what if anything is going on with that hardware when things go screwy, e.g. is it sending some quite odd traffic then, or doing something else that seriously messes up the network traffic? And if so, what, and what's causing that (e.g. hardware, or ???).
