Speed advantages of 802.11g

I am setting up a wireless home wireless network for 3 PC's mainly to
share an ADSL connection.
I am intending to use a netgear wireless router/modem

Can anyone answer the following questions?

1)Is it worth paying the extra for the 802.11g range rather than the
802.11b?


2)What speed advantages would I get when using the internet with
802.11g (through a standard home BT ADSL connection)?


3)If I use a wired connection from the router to the closest PC, will
this have a significantly faster connection speed than the PC's with a
wireless connection?

802.11g uses the same frequency band as 802.11b and so should have
about the same range.

Since 11b (11 Mb/s) and 11g (54 Mb/s) are both much much faster than
any ADSL link, ADSL would be the bottleneck either way.

Most hard-wired home links run at 100 Mb/s and use full-duplex. Some
(old) home links still run at 10 Mb/s. Some (expensive) links run
at 1000 Mb/s (a/k/a GbE). But, for connection through a modem to ADSL,
ADSL will always be the bottleneck.

1. Not for internet sharing - your ADSL connection is not fast enough to see
any advantage with .11g

2. None - ADSL at 512Kbps is handled with lots to spare by 10Mbps
networking.
Faster networking won't make your internet connection any faster.

3. No... the limit is still the ADSL connection not 10/100Mbps or
11/54Mbps....

The dvantage of .11g over .11b is file transfers between computers...
These are lots faster over .11g than .11b - but this does depend on distance
and signal strength.
At longer distances or with a weak signal the speeds will drop - (this
effects both .11b and .11g).

Also remember that mixing .11b and .11g usually slows things down to .11b
speeds...

Cost may be a factor - .11b stuff is very cheap...

I went for .11g stuff myself though and do like the faster file transfer
speeds ;-)

Not necessarily. In the UK a couple of providers will provide an 8Mbps
ADSL link, which is faster than you'll expect to maintain on 802.11b
