...Even a 20Mbps (Megabit per second) internet connection doesn't even come close to touching the old 10 MB/S (MegaBYTE per second) network standards. Keep in mind that there are eight bits to a byte which means that internet speed is really only 2.5MB/S (but most likely you'll be using much less anyway).
Now for transferring data from one computer to another in your network is a different story by most people don't even do this much less need the extra speed to do so with.
Close. Us old-timers will remember that the "old 10 MB/S" Ethernet was actually 10 MegaBIT/S" (not Bytes). But that doesn't really change Tigger's main point. For the VAST Majority, even the oldest LAN adapter is much faster than their Internet adapter, so buying a faster LAN adapter isn't going to help Internet speeds. But that didn't help my Internet speeds one bit.
In my case I have a huge library of (legally purchased) movies on a shared network server, and I can watch them on any of the TVs or PCs spread all throughout my house. THAT is a situation that benefits greatly from a fast LAN, so I have abandoned all of the oldest, slowest LAN adapters in favor of faster stuff.
