As I indicated in my first post, the modem works with other devices & PCs. I also mentioned I've tried hooking up the laptop to the modem via Ethernet. It does not solve the issue. It isn't a wiring issue, but I'm not sure if it's hardware or software with relation to my PC.
Speedtest sites only work when the modem and internet connection are already working, therefore they can't help me. When I have the problem, nothing will load. Nothing. Or it will only kind of load, barely, and then drop again. This will go on and on, for hours, until it stops.
I don't know what causes the problem to go away, but it temporarily does for a few hours now and then.
I tried flushing DNS but that didn't resolve the issue, either.
