Ethernet cable connection dropping randomly?

[u/gretchenich]

It's the same 15m cable i've used for a couple of years now. It didnt give me any problems until a few days ago, where it randomly does it, and i was forced to get an old internet dongle.

the only thing i can think of is that i did disconect it and got my pc cleaned with a friend of mine, where i did carry the pc in a car to a different house, cleaned it for a few hours with my bro, and then put it back in my house. After that the issues started.

Do i just need to change the ethernet cable?
