My desktop has Broadband wired connection - shows connected, but unable to load any web page in Ubuntu 12.04 but works fine with Windows 7.

My laptop - wireless connection shows connected, but again does not load any web page.

Please help. On running sudo dhclient eth1 on my laptop there is no result - see the screen output:prajna@LAPTOP:~$ sudo dhclient eth1 [sudo] password for prajna: prajna@LAPTOP:~$ sudo dhclient eth1 [sudo] password for prajna: after giving password - some time later the screen comes back to prajna@LAPTOP:~$

Welcome to AskUbuntu. Please can you update your question with the details about your hardware and version of Ubuntu? – Mysterio Aug 28 '12 at 18:48
Try to turn your wifi off and on again (with hardware switch if you have one). I'm having the same problem since 12.04 sometimes. I was to lazy to look into it though. I was just thinking it maybe the same error. – André Stannek Aug 28 '12 at 18:50
ubuntu version is 12.04, my desk top connection modem is "wan miniport (PPPoE)" - please explain what further detials do you want? i have taken the connection details from WIN7 & entered them manually in Ubuntu – Pratap Aug 28 '12 at 19:06
tried the wifi switch on / off - no joy – Pratap Aug 28 '12 at 19:06
my laptop - through wireless, & my desktop through broad band phone cable. Even if only one of them is connected still i can not access the web. – Pratap Aug 28 '12 at 20:03

Please try:

sudo dhclient eth0

guess that would be sudo dhclient wlan0 – André Stannek Aug 28 '12 at 18:49
tried the "sudo dhclient wlan0" on my laptop - reply was cannot find device wlan0 – Pratap Aug 28 '12 at 18:59
0f course wlan0, sorry for the mistake. So it looks like you have no "device". So it is important you tell us what hardware do you have. – Misery Aug 28 '12 at 19:05
