so this has nothing to do with A Vs G or N
can my wirelss nic listen to both bands...? is any preferable if my laptop does get both?

5 GHz band of 802.11a - A standard
2.4 GHz band used by 802.11b/g/n - B/G/N standard
I use 5GHz to connect two routers and 2.4GHz to connect clients ( wireless in laptops, desktops... )
The latest wireless standard - 802.11 "N" uses both the 2.4 GHz and 5 GHz wireless bands to provide up to 300 Mb/sec data transfer. If your laptop have nic capable to connect on N standard that is not the same as 5GHz A standard
Please be aware - 300 Mb/sec is the MAX that wireless N is capable of. You results WILL vary, and will almost always be less

first off.... i appreciate your trying to get me on the path to understanding...
but if i have it right...
"A" is the oldest... and ran on 5 ghz originally , that frequency will now also run N
2.40 ghz runs b/g/n

Yes, 802.11a was the first public WiFi standard, and it still runs on 5GHz @ 54Mbps.
802.11b was next, and had about 5x the range of 11a with the same isotrpic power, but had a top speed of only 11Mbps.
Then came 802.11g which has the longer range of 11b with the higher speed of 11a.
802.11n can run on both the 2.4GHz and 5GHz bands... its range is about double the range of 11g, and speeds are up to 6x 11a and 11g when using wide channels (40MHz width instead of 22MHz) and multiple antennae (MIMO Diversity).
Note that Apple, Cisco and Intel do not support wide channels in the 2.4GHz band, though Linksys, Netgear, Belkin, et al do... there are usually only 3 non-overlapping channels in the 2.4GHz band, so when a wide channel is used, it takes up 2 of those and leaves only a single channel for legacy (11b/11g) devices to use.

Some routers will allow for both to be used at the same time.
