How to get my wireless internet to connect with Ubuntu?

If memory serves me, Terminal should be at either : Applications menu -> Accessories -> Terminal or Applications menu -> System -> Terminal.

after installing the ubuntu, did you open the update manager for initial update ? suppose to happen within 24 hrs after installing the cd live after installing the ubuntu, the very first thing ubuntu will do is give you access to internet, so it means, wi-fi suppose to work. if not , try this.. on upper panel, right click the 4 bar icon or the computer icon, mark check 'enable networking' and 'enable wireless' repeat check 'edit connections' click 'wireless' then 'edit' enter ssid and password for wired connection, connect ethernet cable." you should see "auto etho" did you check your laptop wi-fi signal compatibility to router ? b/g/n wi-fi ? if your ubuntu laptop is using "b" and your router is 'g' and your family computer is 'g'. naturally, your laptops can not connect, not ubuntu problem but compatibility of router to your laptop ..only your family computer can connect to router.. try to replace your router with b/g/n signal.. edimax br-6225n is a good router. works on most type of wi-fi signal when got it working, go to system>administration>update manager click 'check' then 'install updates' other concern, go to 'launchpad.net' or type on search 'question ubuntu' it will then guide you to linux question , expect e-mails from linux community in 24 hrs
