From: Ronzlo on 8 Dec 2009 17:52
I installed a D-Link DIR615 wireless router on my Vista PC for remote laptop
internet access. I know this works because I can now log in from my Dell
Laptop (also Vista). The problem is my daughter (using an XP laptop) can see
the new Network, but when she tries to access this there is no response (the
connection tries but doesn't connect). So I think it must be something on her
laptop - any suggestions????
Thanks

Hi
Assuming that your Wireless is secured you have to make sure that the laptop
can match the Wireless Router's security.
Some higher level of security might not be available on her laptop because
it might be old or Win XP is Not updated..
From the weakest to the strongest, Wireless security capacity is.
No Security
Switching Off SSID (same has No Security. SSID can be easily sniffed even if
it is Off)
MAC Filtering______(Band Aid if nothing else is available, MAC number can be
easily Spoofed).
WEP64____(Easy, to "Break" by knowledgeable people).
WEP128___(A little Harder, but "Hackable" too).
-------------------
The three above are Not considered safe.
Safe Starts here at WPA.
-------------------
WPA-PSK__(Very Hard to Break).
WPA-AES__(Not functionally Breakable)
WPA2____ (Not functionally Breakable).
Note 1: WPA-AES the the current entry level rendition of WPA2.
Note 2: If you use WinXP bellow SP3 and did not updated it, you would have
to download the WPA2 patch from Microsoft.
<http://support.microsoft.com/kb/893357>
The documentation of your Wireless devices (Wireless Router, and Wireless
Computer's Card) should state the type of security that is available with
your Wireless hardware.
All devices MUST be set to the same security level using the same pass
phrase.
Therefore the security must be set according what ever is the best possible
of one of the Wireless devices.
I.e. even if most of your system might be capable to be configured to the
max. with WPA2, but one device is only capable to be configured to max . of
WEP, to whole system must be configured to WEP.
If you need more good security and one device (like a Wireless card that can
do WEP only) is holding better security for the whole Network, replace the
device with a better one.
