Debian 8 Jessie: Wireless mini PCI express Ralink RT3090sta Driver installation

Background: Linux Mint Debian running in Mate Environment

Prior to verify the model of you wireless Network Controller, it is important to ensure that Network Manager(which is default in Gnome and Mate) is running.

Issue command: sudo lshw -C network
Please note that *-network UNCLAIMED is shown prior to installing the required package listed below.

Ensure that your /etc/network/interfaces file is clean as mine:

source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback

The most you need to add are the three lines above.

From the above the model is RT3090 Wireless 802.11n
PCIe.

Required package: 'firmware-ralink' and 'wireless-tools' package

Install the 'firmware-ralink' driver (perhaps 'wireless-tools' too if not already installed) to provide support for RT3090 driver.

Issue command: sudo apt-get update && sudo apt-get install firmware-ralink

Important: ensure no Ralink RT28xx driver is blacklisted in /etc/modprobe.d/blacklist.conf

Reboot the PC to allow the driver to initiate.

If the driver is not loaded up after the reboot, initiate the command :

sudo modprobe rt2800pci

If the 'firmware-ralink' is not working, you can try the alternative package 'rt3090-dkms' on Ubuntu thread : http://ubuntuforums.org/showthread.php?t=1669283 .

Hopefully it works by now and you can confirm it by running the command ifconfig or lshw -C network. The 'logical name' row (lshw -C network) is an indication that your device is identified.

Fixing time on sysvinit and systemd

If you have a system that boot using different GNU/Linux init systems such as sysvinit (aka System 5) and systemd (aka System 500) in addition to proprietary Windows system, you may face incorrect time display on one of the aforementioned system. The difference in time display is dependent on the time difference of your location and the UTC time. Further complication may result from concept like Daylight Saving Time (DST). If the Bios is set to localtime, you may fix it in systemd boot system using 'timedatectl' command like: sudo timedatectl set-local-rtc 1 However, if you are using sysvinit and Bios is using localtime, you can set inform the system that local time is being used using 'hwclock' command like: sudo hwclock --localtime or to synchronize the hardware clock with system time and inform the system using: sudo hwclock --systohc --localtime If Bios is using UTC time, you may revert the change with 'timedatectl' like: sudo timedatectl set-lo
