Setting up Ubuntu 14.04

Installation

The following capabilities were already installed.

  • wpasupplicant - client support for WPA and WPA2
  • wireless-tools - Tools for manipulating Linux Wireless Extensions

WPA Config

Created the /etc/wpa_supplicant/wpa_supplicant.conf WPA authentication. TBD: did this help me? 

 gksu gedit /etc/wpa_supplicant.conf

Enter the following 

 network={
   ssid="zdome"
   proto=RSN
   key_mgmt=WPA-PSK
   pairwise=CCMP TKIP
   group=CCMP TKIP
   psk="********"
 }

Name Server

Add the following to the end of /etc/network/interfaces 

 auto wlan0
 iface wlan0 inet dhcp 
             wpa-ssid zdome
             wpa-psk  ******

After a reboot I see 

 cat /etc/resolv.conf# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
     #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
     nameserver 10.0.0.1
     nameserver 205.171.2.65
     search PK5001Z

Also See

 /etc/NetworkManager/system-connections/zdome

Reboot

Wireless was up after reboot. Tried a lot of things on the command line but a reboot may have been the key to getting wireless to come up. See next command line attempts.

References

Command Line Failures

None of these worked to bring up wireless on the command line.

Example 1

 sudo iwconfig wlan0 essid "zdome" key "********"
 sudo iwconfig wlan0 essid "zdome" key s:********

Example 2

The following did not work. 

 sudo ifconfig wlan0 down
 sudo iwconfig wlan0 essid "zdome"
 sudo iwconfig wlan0 mode Managed
 sudo ifconfig wlan0 up
 iwconfig
 sudo dhclient wlan0

freezes

Example 3

 sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -Dwext
   Successfully initialized wpa_supplicant
   ioctl[SIOCSIWENCODEEXT]: Invalid argument
   ioctl[SIOCSIWENCODEEXT]: Invalid argument
 sudo dhclient wlan0

freezes

At the Command Line

Initial Setup

Based on a problem reported in /var/log/messages. (See resources below.) 

sudo mkdir -p /etc/Wireless/RT2860STA
sudo touch /etc/Wireless/RT2860STA/RT2860STA.dat
sudo service network-manager restart

Status

ifconfig
iwconfig
iwlist wlan0 scan
lspci | grep Network
sudo lshw -C network

Configure

sudo ifconfig wlan0 up

The following didn't work. According to some of the resources cited below, the issue may be the the driver was not compiled with the command line option. The GUI option works. 

eepp@tabor:~$ sudo iwconfig wlan0 essid "zdomeWLAN" key xxxxxxxxxx
[sudo] password for eepp: 

eepp@tabor:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     RT2860 Wireless  ESSID:""  Nickname:"RT2860STA"
          Mode:Auto  Frequency=2.412 GHz  Access Point: Not-Associated   
          Bit Rate:1 Mb/s   
          RTS thr:off   Fragment thr:off
          Link Quality=70/100  Signal level:-75 dBm  Noise level:-115 dBm

          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

At the GUI

In the upper right menu <uparror downarrow menu> and selected zdomeWLAN. Followed through with the setup. This worked.
