The version of Ubuntu that you have is unsupported, may as well download a newer version, which may automatically get your network running

I see you have minimized the updates manager there, maybe if you run it, it will install all necesary drivers that arent delivered by default in the ISO you installed. Another thing as mentioned above Ubuntu 10.10 is no longer supported at the moment 13.04 is the version available in the Ubuntu site perhaps you could install that look at this link http://www.ubuntu.com/
Or go with 12.04 LTS (Long Term Supported for 3 years).
Good luck to you.

OK. This means that you have no internet access at all. I would recommend updating your older ubuntu to a new ubuntu. This will allow you to have the newest and best drivers, giving you better hardware support.

Cheers,

The OP can't download updates if he has not internet access on his system.

My suggestions was assuming a hard wired connection was available.

Based upon your previous thread can we assume that ubuntu is still running as virtual machine? How is your vmware virtual network configured?

It really doesn't matter that OP can't connect to internet if Ubuntu isn't supporting downloading packages unless ubunyu has an old stable repo.

@dina How did you solve the problem. I am curious to know, and perhaps other people too
