Hello! I hope you can help me with my problem. I installed the driver for Windows by Ralink. (my PC is Windows 7). When installation was complete, a blank icon appeared on the taskbar. The manual says i should double click it. But when i do, nothing happens. The manual says the Ralink Wireless Utility program should appear when i do that. When i hover over it, it says IEEE802.11 WLAN Not exist.
