Why is 11Mbps Wireless PCMCIA Card better than 125Mbps?  They are more expensive.

Please give an example of Why you are saying the are better and any
references. That is like saying a car that does 50 MPH is better than
one does 500MPH, it depends on what you define as better.

Both cards could have different chipsets and communication bands.

Please give more information on this topic.

May be I guess he is talking about 802.11 a/b/g specifications.

The older specification has higher bandwidth but lower distance or coverage area.

while the newer specification had better coverage and is always better than the 
for your refrence i have copied the text from web below here 
802.11 -- applies to wireless LANs and provides 1 or 2 Mbps
transmission in the 2.4 GHz band using either frequency hopping spread
spectrum (FHSS) or direct sequence spread spectrum (DSSS).
802.11a -- an extension to 802.11 that applies to wireless LANs and
provides up to 54 Mbps in the 5GHz band. 802.11a uses an orthogonal
frequency division multiplexing encoding scheme rather than FHSS or
DSSS.
802.11b (also referred to as 802.11 High Rate or Wi-Fi) -- an
extension to 802.11 that applies to wireless LANS and provides 11 Mbps
transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz
band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the
original 802.11 standard, allowing wireless functionality comparable
to Ethernet.
802.11g -- applies to wireless LANs and provides 20+ Mbps in the 2.4 GHz band.

It depends,

as long as the card you're getting supports the mode you want, it
doesn't really make much difference. Get the faster one.

However, if performance and range are important to you, then it
depends on what card you get.

802.11A is crap. No one uses it. 

802.11b is universal. Almost everything uses it.

802.11g is almost universal as well. Most things support it, and if
not, it can drop down to 802.11b mode, and work with everything else.
