Dear Jen,
I think that everyone at Sony is very well aware by now, that the wifi connection is a joke on this expensive laptop.
Believe me, after reading all 140 pages of this topic, and endless hours of research on the web, I have tried every trick in the book, and also not in the book.
It was a lot better using the centrino adapter, but due to a faulty adapter? or an update gone wrong, or what ever the reason, I started to have difficulties again.
With the broadcom back in place, at least the sound and streaming problems are gone.
But the connection itself, is no better then when I first removed it. A speed that was normal at first with the centrino was 65 Mbps, with the broadcom, if I am lucky to reach 40 Mbps, most of the time it is only half of that. And that is in optimal distance of the router.
And please, I don't want to hear anything about latest drivers, the latest one is 2013!!!!!!!!!!!!!!!!!! Despite the promise that a solution would be given years ago...
Anyhow, I gave up on that a long time ago.
I like the vaio, even with all the shortcomings. I might consider to buy another centrino adapter, if I was only shure that it would not have the same hick up as the one I removed.
Or at least that Sony would give an alternative for an adapter to use, instead of pretending a nose bleed....
