No way it's megabytes per second. WiFi G mode provides a theoretical cap of 6.75MByte/s, and we all know you'll never see that. Protocol overhead combined with interference and range, and you're lucky if you can keep it above 1MByte/s.
Yes, WiFi N is proliferating, but it still has a host of caveats. A single-channel N device with a 20MHz span, instead of 40MHz, still only gets 9MByte/s theoretical max.
Yes, I know, you can use a wired connection. You can have dual-channel N and you can use 40MHz span, but we're talking about average rates. Most folks I've seen don't use wired. Most N devices are single-channel, and I read again and again that most 2.4GHz networks will actually perform better in 20MHz mode (due to interference)
