Ubuntu: No internet connection while installing ubuntu 12.04


Currently I am running Windows 7 on my PC. When I boot to Windows, it connects to the internet.

But when I try to install Ubuntu 12.04 and boot from the flash it shows Disconnected - You are now offline.

I am using wireless internet, and I also tried connecting directly from my router to my PC too, still I cannot connect to the internet.

Anyone has an idea how fix this very annoying problem?

the output of ifconfig is as bellow:

    eth0      Link encap:Ethernet  HWaddr 62:d5:10:5d:82:31              UP BROADCAST MULTICAST  MTU:1500  Metric:1            RX packets:0 errors:0 dropped:0 overruns:0 frame:0            TX packets:0 errors:0 dropped:0 overruns:0 carrier:0            collisions:0 txqueuelen:1000            RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)    lo        Link encap:Local Loopback              inet addr:  Mask:            inet6 addr: ::1/128 Scope:Host            UP LOOPBACK RUNNING  MTU:65536  Metric:1            RX packets:16 errors:0 dropped:0 overruns:0 frame:0            TX packets:16 errors:0 dropped:0 overruns:0 carrier:0            collisions:0 txqueuelen:0            RX bytes:1312 (1.3 KB)  TX bytes:1312 (1.3 KB)  


I had the same problem with my hp dv6. After a lot of playing around with things and making sure the right drivers were installed, I tried checking my Bios settings and reset to default. Apparently that did the trick for me I guess when they install windows on laptops it changes something in the Bios.


Try connecting to the internet directly with an ethernet cable, not through the router. Just disconnect your router from the internet and plug the cable into your computer. Does it work? If it doesn't then there's a problem with the network-manager package.

I suggest to make the flash drive bootable again. Or you can install Ubuntu without connecting to the internet. You can connect later, after the installation. Let me know if it worked. If not i can help you fix your network-manager package
