Until this morning, my computer had no problems automatically connecting to the router. Now I can't even manually connect to the network my D-Link router is on at all. Details on the router: has the latest firmware, hardware ver. B2. All the other devices (like gaming consoles) and computers in my home have no trouble connecting to that router.
I'm connecting to that router with my comp using wireless connection with D-Link DWA-552 network adapter. The adapter is also upgraded to the latest driver and I can get onto other connections in my home network. It's just the D-Link 615 I cannot connect to.
