I have been using D-Link's router model # DI-524UP in wired mode for my laptop. Now, I want to use a second laptop to connect to the router in wireless mode.

The second laptop's current OS/security setup is as below :-

a) Win-XP SP2 (completely patched, vetted by Secunia)
b ) AVG AV/AS free 9.0
c) ZA firewall free 7.0.483
d) Sundry utilities/protection software : Ccleaner, Spywareblaster
e) Safe browsing habit

Yes, I shall be upgrading the OS to XP-SP3 within the next three months.

Since I do not understand the wireless security aspects, I had requested a friend, more knowledgeable than me, to do the wireless setup. He tried to setup the router for WPA, but could not due to unknown reasons, so settled with "open system - WEP enabled".

Please advise how to make the second laptop work in WPA mode.

Thanks,

First you should use WPA2-PSK if available as it is the most secure protocol. You will need to enable the setting in your routers wireless settings, preferably from the wired computer, and establish a PSK(Pre-shared key) in the provided space on the router. Save out of the router. Go to the wireless settings on the router and set for WPA2-PSK and enter the same PSK you entered on the router. You should now be able to connect.
Get your facts first, then you can distort them as you please.

I don't believe a XP - SP2 machine can do WPA(without a specific update), I could be wrong. But I seem to remember that WPA/WPA2 was an update in SP3. So you might have to update to SP3 before WPA can be used.

Again I could be wrong and perhaps if one of the OS people read this they could correct me if I am wrong.

If your only choice is WEP, my advice would be don't leave the PC turned on and to change the WEP pass phrase often.

TIME FOR MORE INFO THAN YOU NEED TO KNOW!

WEP send its authorization with every packet. All someone has to do is collect enough packet (150,000 or so more is better) run that info through a program and up pops your password.

WPA/WPA2 authorizes your connection only when you first connect with a 4 way handshake. From that point on you are encrypted. So someone has to collect those 4 packets and then run a program with a list of words to find your pass phrase and if your pass phrase is not in the list then it doesn't get cracked. So with WPA/WPA2 because you can use numbers, letters (caps and lower case and it matters), symbols and spaces, I always recommend a 4 - 5 word sentence for your pass phrase.

SO ENDTH THE "MORE INFO THAN YOU NEEDED" SECTION

hehe
