[gianluca <antonelli1970@xxxxxxxxx>]

Hello Christopher, thanks for the mail.

It took me one week to reply since I wanted to make some tests with
different wifi.

I upgraded the BIOS:

 sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

A06
11/07/2014

Then, due to a business travel I tested the laptop in several
situations. The outcome is a little bit surprising for me in the sense
that there is a strong improvement but the problem is not totally solved
yet while I expected a stationary situation or the complete solution of
it.

It now connects very nicely to my home wifi and to my smart-phone hot
spot (it didn't before). It connected to the wifi of a couple of
airports but I experiences problems with EUDORAM (the academic network).

So, let me say 8 out of 10 worked fine.

Thanks for your help, I'm a little bit unsure on how to proceed,
g.
