Well, unless you have an old Bcom wireless card, you can remove the b43 packages without a worry. The other wireless drivers should also be safe so long as you are sure you aren't using them.

so I have an old toshiba laptop (which used to be windows vista but I upgraded it to windows 7) and it is core2duo and the wireless card is intel(R) wireless wifi link 4965agn, which works really well.
I bought a new laptop recently which is made by lenovo, windows 8 touch screen, 8GB RAM and i7. However, the wireless card SUCKS. It can't connect to anything at all.
