Unable to connect to internet

I have a problem with my internet connection; simply I am unable to connect to the internet. Under the device manager, says that there is nothing wrong with the hardware. I did perform all the standard fixes, such as turning off the computer and modem for 5 minutes. I know the problem does not lay with the modem or the router because I am able to connect to the internet connected to the modem or the router. Now, my question is could this be a malware problem, or is this a hardware problem? I am asking for help on another form for malware problems. If this was a hardware problem, wouldn’t it come up on the device manager, and what can be done to correct this problem?
Thank You
