Make sure your router has DHCP enabled and Ubuntu is set to configure IP address automatically.

And then from shell, try to ping some website.
Like :
ping yahoo.com

If you get something like this :

Code:
rick@iosta [~]# ping yahoo.com
PING yahoo.com (98.139.183.24) 56(84) bytes of data.
64 bytes from ir2.fp.vip.bf1.yahoo.com (98.139.183.24): icmp_seq=1 ttl=48 time=74.0 ms
64 bytes from ir2.fp.vip.bf1.yahoo.com (98.139.183.24): icmp_seq=2 ttl=48 time=110 ms
64 bytes from ir2.fp.vip.bf1.yahoo.com (98.139.183.24): icmp_seq=3 ttl=48 time=74.1 ms
64 bytes from ir2.fp.vip.bf1.yahoo.com (98.139.183.24): icmp_seq=4 ttl=48 time=75.6 ms


But there lots of other things too.. Keep us posted...

There is the problem, I think.

Broadcom always requires installation of their proprietary driver which on normal PCs, requires a reboot. So, I don't expect it to work in Live mode as the botched open source driver is most likely working.

I dislike Broadcom. Atheros and Ralink are much better for Linux users.

If you will install Ubuntu, "install" and then install Broadcom's driver, you will be able to use. Not through "Live USB" because Broadcom's driver will require a reboot.

^ ifconfig is being depreciated. However, it will still work. :)

ip is the new command.

And ip addr is the equivalent of Windows' ipconfig /all.

I tried to enable the broadcom driver from setting but even though its not working. I think this is why people don't use Linux. It has lots of problem for everything

There are advantages and disadvantages with any Operating System. In the beginning you will have to overcome some obstacles but once you get the hang of it Linux is not that bad.

Generally the "broadcom-wl" driver works best for newer cards. Check if that is the one you have installed.

Could you open a terminal and post the output of lspci command?

you can notice that when using wifi your pc is getting ip 192.168.0.104 while using wired connection your pc is supposedly getting ip 192.168.0.1,why is that?post your router wifi settings as well as wired/lan settings here or try to find the difference between them(like dhcp,starting ip etc) yourself.

i notices the difference, but i dont know what to do now, i want to use linux for everything, but i am not an genius, windows never gave me any problem like this, why linux why ?

i dont know why the people at linux decided to make linux like this, on windows just install os - install drivers - thats it no problem ever no nothing at all,

any layman can install and configure windows, but with linux no way, you have to spend hours and hours on online searches and tutorial just to get simple wifi working

i was a big supporter of linux and liked their idea of Free OS, but no way we dont have all the time in world just to get the net working, which works without any problem on Android, MAC, and windows,

Bye bye linux

Linux was never designed for average users in the first place unlike windows & mac.if you can't put in the efforts because of bad luck with drivers/hardware/software then it is better to stick with windows.

i am on dual boot with windows 7, everytime i have to post on this page, i restart my laptop longin windows and post here, and agains restart and login on ubuntu, to try what you suggest

Also as the wifi net is not working on ubuntu, i have to use a awired connection, now my wifi router is setup on a very high place near my ceiling on the room, so when i have to try your suggettion, i connect to the wired connection holding my laptop on one hand and typing with another,

that is very irritating, and disturing and that type of things make people hate linux, which after so many years still have many problem

the fact is that windows works out of the box, but linux never works without any pain,


i love linux and i want it to success, but why problem always, why dont they design it for the general public

no one want to type long command, so no point of having terminal, but linux still has it,

any way i will give it a last try and see if it works or not

please help if anyone really know how to solve this porblem

ok some how i got it working now on my laptop and now i am posting it from ubuntu connected through wifi

here is the link to solution

http://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers


  • Uninstall the bcmwl-kernel-source package by issuing the following command on a terminal:
    sudo apt-get remove bcmwl-kernel-source
  • make sure that the firmware-b43-installer and the b43-fwcutter packages are installed (of course you will need internet by others means):
    sudo apt-get install firmware-b43-installer b43-fwcutter
  • type into terminal:
    cat /etc/modprobe.d/* | egrep 'bcm'
    (you may want to copy this) and see if the term 'blacklist bcm43xx' is there
  • if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf
    put a # in front of the line: blacklist bcm43xx
    then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly).
  • reboot

    i wil post a tutorial on this and hope admin will make it a sticky

good to know.from above solution it seems like you have to comment out bcm43xx in blacklist config file to allow install of this particular series driver.
