Public bug reported: I have a machine which had ubuntu 12.04 preinstalled, and i did a fresh install of ubuntu 13.04 a few months ago, and had to manually install the drivers for the wireless adapter. The wifi and ethernet worked flawlessly after that, until last night, when i was working on some ftp work for my website, and i started uploading a 50mb file, and the system hung. I used the system reset method of "Ctrl+Alt+SysRq+R-E-I-S-U-B". When the system rebooted, the wireless wasn't working, and in the indicator applet it said "device not ready" under the wireless section. Initially, even the ethernet wasn't working, but after a little while, it automatically started working, thankfully!
I ran a few commands in the terminal, and i'm pasting the outputs below. rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no lspci 00:00.0 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Root Complex 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Richland [Radeon HD 8450G] 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Trinity HDMI Audio Controller 00:04.0 PCI bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Root Port 00:05.0 PCI bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Root Port 00:07.0 PCI bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Root Port 00:10.0 USB controller: Advanced Micro Devices [AMD] FCH USB XHCI Controller (rev 09) 00:10.1 USB controller: Advanced Micro Devices [AMD] FCH USB XHCI Controller (rev 09) 00:11.0 SATA controller: Advanced Micro Devices [AMD] FCH SATA Controller [AHCI mode] (rev 40) 00:12.0 USB controller: Advanced Micro Devices [AMD] FCH USB OHCI Controller (rev 11) 00:12.2 USB controller: Advanced Micro Devices [AMD] FCH USB EHCI Controller (rev 11) 00:13.0 USB controller: Advanced Micro Devices [AMD] FCH USB OHCI Controller (rev 11) 00:13.2 USB controller: Advanced Micro Devices [AMD] FCH USB EHCI Controller (rev 11) 00:14.0 SMBus: Advanced Micro Devices [AMD] FCH SMBus Controller (rev 16) 00:14.2 Audio device: Advanced Micro Devices [AMD] FCH Azalia Controller (rev 01) 00:14.3 ISA bridge: Advanced Micro Devices [AMD] FCH LPC Bridge (rev 11) 00:14.4 PCI bridge: Advanced Micro Devices [AMD] FCH PCI Bridge (rev 40) 00:14.5 USB controller: Advanced Micro Devices [AMD] FCH USB OHCI Controller (rev 11) 00:18.0 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Function 0 00:18.1 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Function 1 00:18.2 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Function 2 00:18.3 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Function 3 00:18.4 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Function 4 00:18.5 Host bridge: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) Processor Function 5 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
