I installed Ubuntu 12.04 via Wubi. It does not detect my Wireless adapter

Hi Ramakrishnan
everything you should do is searching for additional driver in dash and let it search for driver
after select the best driver and click active
it's everything you can do to solve the problem of not recognizing wireless adaptor

What make and mode is the system?
What wifi chip do you use?
How can you expect any intelligent reply from "My wifi doesn't work" without such basic details as this....?

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

Thanks

@numb95: Does this mean that Ubuntu already has all drivers in an offline cache? Because I have no internet connectivity in Ubuntu!

@andrew-woodhead666:

I am sorry, but I did not know what data is exactly required. If you could list the details you need, I shall gladly give them!

I also tried using Wired connection, even that is not detected! Also, the output of the command you said is below:

ram@ubuntu:~/Desktop$ sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

@andrew-woodhead666: I had no idea I was doing that. As you say, that is not for the layman to understand. Also, I made no changes to what Wubi was doing - and as Wubi is for the layman, I think there's a bug with Wubi itself.

I shall indeed go ahead and report a bug! Thank you!

You have installed a pre-release and not the stable version :)

Bugs get things fixed :). I suggest you use a wired connection and get updated. It may help

Thanks actionparsnip, that solved my question.
