I got a new Dell 3437 laptop, when ONed the laptop ubuntu started to install intself. But at the end some packages didn't installed properly like "Update Manager". After that I am not able to update or upgrade and the laptop came with 12.04 version. Meanwhile the wireless driver got updated, now I am not able to use Wifi also. I tried to reboot the system and install again, but it is not working or I don't know how to do it.
I checked with Dell Support they are not understanding, the support guy told to install Windows, then they will help, I told I dont't want windows and purposefully taken Ubuntu the guy didn't understand at all.
Now I planned to download a ubuntu 12.04.03 LTS and then install again in the laptop.
What is the suggestion. This is a brand new Laptop bought yesterday only.
