You can use router of G or N type and the same type wireless adapter. Of course you can use wireless N adapter with G-type router and reverse.
You can just disable device, there is no need in disconnecting the G adapter.
Belkin Wireless-G Network Adapter report that it works great,but they don't seem as thrilled about installing it.
You can't.
It depends on the type of wifi adapter. The 3 most common ones are b, g, and n. First check the type of adapter your laptop has. Mine, for example, is wireless n. If you have a wireless g adapter then upgrading to a wireless n adapter would be a good choice. Alternatively, upgrading you're router to wireless n (if you're laptop is wireless n) would work too.
Wireless adapter of G type connect work in N type network. To take advantage of N networks you need to have N type network adapter.
Neither. Both G and N, as well as A and B, are wireless networking standards.
Yes, a wireless n adapter is backwards compatible with wireless g. Check the box you are buying and it will tell you if it is compatible with which wireless ranges.
no robots will come out and kill you
G or N .
If you are talking about building of wireless network. Then you need a wireless router and a wireless network adapter (if you have a laptop you might not need it). If you have a desktop you rather will have to purchase a wireless network adapter. Pay attention to what kind of wireless network you are going to build. It can be a, b, g, and n types.
You can't. You will need to purchase a new router.
