hi,some stupid question about e1705 built-in wireless card

hi,I'm a newbie of laptop.
yesterday,I asked a question about wireless card of my dell 1390 card.after doing some research on the internet,I get to know wireless capacity of a/b/g.since I'm an internet maniac who cannot live without it,I'm very anxious to get on thing clear:how fast is a g wlan network than a b wlan network?and since I didn't choose the Intel card,what's the capacity of my 1390card?if it's only b capacity comapatible,I'll think about replacing it.
at last,one more stupid question,where can I find my MiniPCI slot on my laptop and what's the difference with the ExpressCard slot?
some expert to explain?

 

b is 11 mb/s
g is 54 mb/s

but it doesnt matter because you're limited by your internet connection which is significantly slower than either b or g

the only time you need to worry about b or g speeds is over when transferring files over a LAN, but even then i would just plug with with an ethernet cable and get 100 mb/s.

minipci slot is underneath.

 

When talking about wireless speeds, you have three factors to determine the speed of your connection:

1. Quality of signal
2. Speed of source vs. # of users
3. Quality of hardware.

In basic terms, if you're in a hotspot with dedicated wifi, it should not make a difference, as connection strength will be high, and the speed of the source will be high enough to handle its users but significantly lower than the throughput you can get with wlan.

If you're bootlegging a connection from neighbors, wardriving, or surfing from an unsecured connection, your main concern is quality of connection; You might be connected at a relatively low speed, and your source might be on 300kbps DSL with 2 people already using it. In either case, the difference between b/g plays out in idealized conditions only; in normal use, you will not be able to notice it.

If you're setting up your home network, get a G base that is as clear and powerful as you can afford (read reviews.) Otherwise, the difference between b and g will not come into play, other than minor optimizations in signal quality over distance.

 

I'm such an internet maniac that my wireless is turned off.

I still prefer wired for its fast, steady connection.

I just use wireless out in public spaces and so forth.
