Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I just upgraded my system from a 11.04 wubi installation (windows dual boot) to an Ubuntu 11.04 stand-alone installation on my IBM thinkpad r50e.

I think I got the very same trouble evinced from other users, but expecially as the one found in this forum: I don't get internet on wireless connection

While previously, under windows, the connection worked flawlessy (indeed under windows and wubi too), now I'm unable to get a stable link, and the speed shown running a "connection informations" is very low if compared with the one shown on windows or on the previous wubi version of the same O.S.

As suggested on the linked previous 3d, I ran a ipconfig and a ping -qc1 example.com;ping -qc1, posting hereafter the results.

Thank you very much for your valuable support.

Here is the output of iwconfig:

and my ping output:

Since I'm Italian, you can see some Italian words in the output, I don't think this should be a problem. Anyway, if you need a translation, I'll be happy to provide it to you.
