http://ubuntuforums.org – Hello, I am running Windows 7 x64 with Ubuntu 12.04, dual-boot. I'm fairly new to Ubuntu. The wireless connection displays "device not ready" when I boot up. However, when I plug in the Ethernet cable and then remove it, the wireless connection works fine. description: Wireless interface product: RT3090 Wireless 802.11n 1T/1R PCIe I've read several threads and tried to fix it on my own but have had no luck. I tried installing the broadcom 43 driver but to no avail. Any ideas and help would be appreciated. Thanks (Hardware)
