Dell seems to have played with the integration so Broadcom can't do much. And DELL is supporting the comp in it's delivered state.
Hm. Hard to say. The comp is 4 years old. If I put endless new hardware in a comp I think support would not be valid. I can understand this for a new OS too.

I think the problem is that they have changed the standard adapter in a way that it seems to be the right one. If they would have changed this so that M$ can say "unknown, will not work" one would not waste time on searching on the wrong place.

Now I have a useless port but is was not a big deal.

>>My DELL, the one that was original shiped with Win 7 had a big problem with Win 8.1 The Broadcom card that is on board will not run with the drivers that come with Win 8.1. DELL does not provide a Win 8.1 driver - at least this was the state 14 days ago. Only solution was a new network card.
>>Also a new soundcard driver that was shipped bei MicroSoft was stopping media streamin out of the net. The one orignal shiped still works.
