wireless 11g is 54Mbps and operates in the 2.4 GHz band, 11a is 108MBps and operates in the 5 GHz band

wireless 11b is 11MBps and in the 2.4GHz band as well
Where did you get that info from?

Here it is plain and simple:

802.11A
Theoretical Throughput: 54Mb
Average Throughput: 30Mb
Frequency: 5GHz via Orthogonal Frequency Division Multiplexing (OFDM)
Theoretical Range: 300ft (100m) radius
Average Range: 200ft (67m) radius

802.11B Wi-fi
Theoretical Throughput: 11Mb with 5.5Mb and 1Mb Fallback
Average Throughput: 8-10Mb
Frequency: 2.4GHz via Direct-Sequence Spread Spectrum (DSSS)
Theoretical Range: 1000ft (333m) radius
Average Range: 500-700ft (167 - 233m) radius
Compression Ratio: 2:1 (22Mb via TI Compression Algorithm)

802.11G Wi-fi+
Theoretical Throughput: 54Mb with 11Mb, 5.5Mb, and 1Mb Fallback
Average Throughput: 20Mb
Frequency: 2.4GHz via Direct-Sequence Spread Spectrum (DSSS)
Theoretical Range: 1000ft (333m) radius
Average Range: 800ft (267m) radius
Compression Ratio: 2:1 (108Mb via TI Compression Algorithm)
Backward Compatible with 802.11B via fallback.

802.11A/B
Device that can accept both A and B connections

thats exactly what I was saying, cept I thought that the A did up to 108, but I guess it accomplishes that with two connections or however it was described above, and I thought G could only do up to 54.
other than that tis the same. I have a Atheros A/B/G card so I can connect to any of those. (well I could if it wasnt being a b!tch of a thing to get working on my laptop in BSD)

btw these are the different connection rates for 11b and 11g respectively
ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
