Wired PC Internet problem

[vukovarac4ever]

Hello and thx for future help. For few days I noticed problem with Internet on my wired desktop PC. I should get up to 4 mbit speed so I checked on www.speedtest.net and speed was around 1.2 mbit even with my Wifi off. Then I checked on my wireless devices and speed was normal 4 mbit (430 kbs download speed) . Tried everything, reinstaling windows, scaning with multiple antivirus programs, factory reseting router multiple times. There are moments when speed on my PC is normal, like 3.5- 3.9 mbit but suddenly it drops to below 2 mbit and I dont know what is cause of that. Everytime I check my wireless speed on my phone for example (speedtest) its normal, 4 mbit but only on wired PC is not. What could be cause of that and how should I fix it?

if it drops without reason maybe your windows is updating the system in the background.

or a virus using your internet connection.

run a full scan just in case.

When it happens , check the task manager and see if any program is using the network ... it looks fishy to me...
