I have a netgear router and for some reason, my network could not be deteceted. So i did a master reset and connected the router as a fresh device and took it again from there. all worked then.

what's probably happening, I'm guessing that the computer light is on but the router is waiting for a response from the pc or the other way round. if you do a fresh install of the router than it should be fine but yeah do all the updates for windows first and have a look to see if there is any new firmware (drivers) for your router then take it from there. a hard reset normally works in nearly every situation
