Security and request for 11g product recommendations

Hi

I'm thinking of buying a router that supports 802.11g
and have some questions:

1) How does WEB and WPA affect the performance?

2) Is it WPA instead of WEB? or is it a combination?

3) What other things should I consider regarding security on
my wireless network?

4) Is there anyone that have any experience with the
following products:

a) 3Com® OfficeConnect® Wireless 11g Cable/DSL Gateway
b) 3Com® 11a/b/g Wireless PC Card with XJACK® Antenna
c) D-Link DI-624+ AirPlusXtremeG+
d) D-Link AirPlusXtremeG+ DWL-G650+ Wireless CardBus adapter

5) Is there any other 11g products that you can recommend?

regards

It's one or the other, it turns out that WPA is no more secure then WEP. But
it's unlikely that anyone will spend the time and effort necessary to crack
your domestic wifi to obtain some information.
Any credit card no.s or bank details would be protected by the SSL layer
within the browser anyway.

You need to set up the MAC addresses for all your equipment to prevent
others connecting to your network,
but even that can be defeated.

3Com should be good but expensive. I use Draytek Vigor 2600We, all the
features, easy to set up and very reliable. I you really need 54Mbs
(remember it just on your network, no advantage for ADSL) the 2600G should
be available now, depending where you are.
