My computer was purchased a month ago, and the connection has been working flawlessly up until yesterday. It shows that I have a limited connection. I have an HP desktop with internal wireless (Atheros AR9485), running Windows 8.1. The router, a Netgear WNR3500v2, is located on another level of the house, but all other wireless devices in the house work fine, which include my laptop that I am currently using right next to my desktop. I have updated the firmware on the router and the driver for the AR9485 and I still have a limited connection. The settings on the router were not messed with at all, so I am at a loss as to why this randomly became an issue. Any help would be greatly appreciated.
