Hello, I need to get a wifi card for my laptop (no wifi at this
time). I'm not an expert on this, hence the reason I'm here - to hear
from you experts out there !

WiFi Coffee shops, libraries, etc. are transmitting using what...802.11b/
g ? The newest cards are 802.11n right, so if I get a 802.11n wifi
card, will I be able to use it on 802.11b/g network?

Any guidance will be appreciated.

J

Correct.

>The newest cards are 802.11n right,


PRE-n -- 802.11n has NOT been approved, and there is no guarantee PRE-n
products will be compatible with the final standard. I suggest buying a
good (and cheaper) G card instead.

Yes.

Thanks for answering

ok, but what happens when 802.11n does become a standard and coffee
shops upgrade, will my 802.11g card still work on an 802.11n network?
And if it does, obviously not at full bandwidth...

Your G card will still work, and even a B card is faster than the
Internet.

that always amazes me..... when people say...
I need a FAST card with 22mbps or 54mbps -
so I can use it at the local WiFi hotspot - that is running a 1.5mbps DSL
line !

then again - our local library is running a 20mbps network node on our local
muni network node.

Suggestion.. Quit reading ads and listening to the lies by the
salespeople....
You used one word above ("obviously"), that assures you have no interest in
the truth but in the lies the salesdroids are telling you to try and get
your money... Hint.. if their mouth is moving when they talk, they are lying
(PS, i'm not a salesdroid and am typing not talking! Whew

so I take it speed is not the issue. Then I deduce
it's....distance ?? Then again, if I'm sitting IN the coffee shop I
should have no problems with distance. But if I were say a hacker
sitting across the street in the back of my van, then distance would
be an issue. This begs the question...why not keep the distance short
so no one can be out of sight??

It could be. The real point is that N is totally unnecessary for a
coffee shop. Even B is more than good enough when there's no security.

If I were responsible for the coffee shop, I'd recommend WPA Enterprise
with a RADIUS server, with a small printer to print out time limited
authentication credentials for paying patrons, which would essentially
mean going with G over B. That way all connections would be isolated
and secure. I'd also recommend a high-grade router with traffic shaping
so no one patron could hog all the bandwidth, and blocking of
filesharing.

Correct.

Some places do just that, but it can often be defeated with a high-gain
antenna. Others use authentication to keep out the leeches, which is
much more effective.

Speed is NOT the issue, and distance may *NOT* be any different.. have you
noticed they ALWAYS use the weasel words "range UP TO" 4x 8x 10x etc... is
there any promise of more, or are they just saying that it CAN be more?

While it changes on a daily basis, i have seen long distance records for
standard B/G wap's (with custom antennas of course) of 63miles, and last
week 231 miles, and there is talk of putting something on the space station
so you will get a range of many thousands of miles!.....

at any rate, not sure where you are, but I used skynet of spokane
(http://www.spokaneskynet.com ) several HUNDRED square miles of hot spot
area, with standard b/g stuff....... There are many other providers that
serve many other areas See the map at http://www.onelasvegas.com/wireless
and select your state
