    Realtek RTL8187: Wireless not working in 13.04

    Hello,

    I just installed Ubuntu 13.04 today, I had no problem connecting to the internet during install. Now when I try it looks like its connecting but after about 30secs it says disconnect - you are now offline network. I have tried disconnecting the stick and deleting my wireless connection once again and restarting my computer. Sometimes it will say its connected right when the computer is turned back on but firefox wont work... when I try to disconnect and reconnect it won't connect. I would like to solve this problem as fast as possible if someone could please give me hand that would be greatly appreciated. Also I am new to this so go easy on me please
    Thank You!

    I am doing this on my roommates computer so please keep that in mind.

    Re: Wireless not working in 13.04

    The first thing we need is the output of "lspci" that will tell what type card you are using! If it is a usb then "lsusb" will tell us what card it is.

    The second thing is "lsmod" that will tell us if the module is being loaded for that card!

    The third thing is "ifconfig" that will tell if the wlan wireless is working.
