Could this problem be motherboard related?

I have been experiencing 3 seconds connection losses every 15 to 30 minutes for a month now. The problem started when I was using an ethernet cable for connection. So I thought maybe I had the change my cable and I did that. But it didn't fix my problem. Then I said maybe it was the ethernet port of the motherboard which went bad. I bought a new USB Wireless Adapter to try it out and see if the problem persisted on Wi-Fi and yes, it did. Same thing keeps happening even on Wi-Fi! This is very frustrating. Note that this problem only occurs in my PC and other devices connected to the same internet have no connection issues.
So I wanted to ask that if the problem could still related to my motherboard or is it more likely to be something of software-origin.
Any help or advice would be great! THANK YOU!
