HOWTO post a Wireless issue (ticket)
Please take a while for the title of the thread. Do not write things like "Help wireless" and "Can't wireless". Think a little bit more, a good title can increase the chances to get help. For instance, add the Wireless brand/Ubuntu version/Machine Brand and Model.
Please, provide details about you Wireless. The diagnoses of your problem can be easer and the solution faster.
Here is a list of Wireless related information with their respective commands. Some commands give you a lot of output, so will be nice to include in the post only the information regarding the Wireless. You can cut it or use tools like grep, or whatever you like.
1 ) Machine Brand and Model (PC/Laptop):
2 ) Wireless Brand, Model and Wireless Chipset:
Get it from your product information.
(hint) use grep to get only information about the Wireless
3 ) check interface:
$ lspci -nn | grep 'Wireless Brand'
(hint) if the Wireless interface name is wlan0 you can also use
4 ) Check for modules:
(hint) search for the Wireless module
5 ) Kernel boot messages
$ lsmod | grep "wlan_module_name"
(hint) the same as in (4)
6 ) Network configuration
7 ) Scan for networks:
$ sudo lshw -C network
(hint) the same as in (3)
8 ) Ubuntu Version:
$ sudo iwlist wlan0 scan
9 ) Kernel/architecture (including 32 vs. 64 bit):
10 ) Restarting the network:
Add this information to the post, even is the output is and error, and more if you have, and describe your issue. Please use CODE tags around the output when posting.
$ sudo service networking restart
