Greetings,
It may be that Network-Manger needs WiFi turned on - It is the icon in the top right of your screen.
The icons in order on your screen are: an envelope for email, a battery symbol, Network-Manger, volume control for audio and then the time.
Right click the Network-Manager icon (a stylized radio wave beacon) and be sure that both "Enable Networking" and "Enable Wireless" are checked and therefore On.
If wireless is functioning, left clicking that same Network-Manager icon will list the status of your connections as well as available wireless services.
The following command will indicate if your wireless hardware is operating AND connected:
with output like (colored items will be different and specific to your situation: red items will be determined by your system's identification and naming conventions while green are the ambient operating conditions):
Code:
wlan0 RT2860 Wireless ESSID:"whiffle" Nickname:"RT2860STA"
Mode:Managed Frequency=2.412 GHz Access Point: 00:00:5A:3D:33:8D
Bit Rate=54 Mb/s
RTS thr:off Fragment thr:off
Link Quality=100/100 Signal level:-59 dBm Noise level:-83 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
but if the wireless hardware is on but not connected it will look like:
Code:
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=100/100 Signal level:-49 dBm Noise level:-115 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
and if the wireless is turned totally off (keyboard switch etc.) it will look like:
Code:
wlan0 RT2860 Wireless ESSID:"" Nickname:"RT2860STA"
Mode:Auto Frequency=2.412 GHz Access Point: Not-Associated
Link Quality=100/100 Signal level:-49 dBm Noise level:-115 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
