Random internet disconnections :O

[Lokson]

Hello everyone.
I have a problem with internet connection. I have moved to another flat and changed internet provider. From now on I have an internet gaps from time to time. It's hard to say how often but surely few times an hour. It's not a problem with router ( I have checked with another PC). I formated HDD and installed latest mobo drivers. BTW Internet is provided by ethernet cable.

Please, any idea what's wrong?

Specs:
MSI 760gm-p21 f
AMD FX6100
8GB RAM (some shitty Spectek)
Akyga LPG12-35 PSU ATX 550W
MSI Radeon 7850


ipconfig/all
Sorry for polish language.

Can provide example Wireshark on demand.

It's most likely something to do with the internet provider. Either they are having server issues or a lot of people use that provider in that area so the internet gets clogged up causing random drop outs.
There could also be a faulty wiring somewhere but I doubt it.

Yeah, but why internet works perfectly fine by WiFi or by ethernet on other PC. Every device besides my PC works just fine.
