2 Months ago I did a factory reset of my laptop, and that brought strange behaviour to my internet. I did several hitman pro virus scans on my laptop and nothing bad came up. But my internet has been acting weird since I did the factory reset. Especially on my phone, when I’m in my room where the internet box is, the bars on my internet go from 4bars to 5bars every 5-10 minutes. I did the F-Secure router check but I’ve seen people say it’s not the best router checker. I read an article of router/dns hijacking and it said “Websites loading a bit slower than usual.” There were many other points that didn’t apply to me (thankfully), but as I said, reddit loads a bit slower than normal. So, any way to check if my router has malware?
