Multiple ethernet connections kill the internetspeed

[rtriumf]

So i have my main computer with ethernet cable(computer 1). If i plug computer 2 and/or ps4 with ethernet, computer 1 slows from 90mbs to 5 and the internet barely works. If ps4/computer 2 are on wifi, everything works fine. Ideas? Scanned for malware, tried different ethernet cables etc.

What router do you have ? some have features to allow faire sharing of the bandwidth to limit 1 device stealing all of it , in Windows Server setting we call it Load Balancing , what it does , it makes sure there is enought bandwidth for all devices and not just 1 is stealing it ... maybe check if you have settings in the router that affect this.

hope info is relevant to your situation.
