No internet via WAN but networking fine

Right, any help on this one much appreciated. My laptop basically
stopped working via wireless, losing all internet and network
connectivity (some time mid march and hadn't done anything that would
explain it). Well, at first I was able to browse to other machines
but if i tried to copy anything larger than a few KB was told that
the
network name was no longer available (although it was). If I
persisted some pages would sometimes load, but 90% of the time would
time out. At all times the laptop has stayed connected and has
succesfully got an IP address via DHCP. So I've ended up trying to
use a static IP, rebuilt my winsock stack, reinstalled TCP/IP, ran a
thousand virus and adware scans (all OK) but have been unable to get
to the bottom of it.

I know the router (Netgear WGR614) is fine as another laptop on the
wan is unaffected, as is a desktop hardwired. I then I plugged the
laptop
into the router and all was fine! Why I waited until now to do this
I
have no idea. So it must be a wireless driver issue or something so
I
uninstalled and reinstalled that. Then last night - success - pages
were loading. Alas, it was short lived. Then this morning all was
working fine - for a couple of hours and now the problem has
reoccurred :(. Internal networking is still fine - I using VNC to
connect to my desktop and write this but am unable to do it directly
on this laptop.

Is it possible my wep settings have corrupted on the laptop? I'm
using WPA-PSK.

So I'm almost out of ideas. Answers on a BIG post card please google
world...

Cheers.....

Hi
Both Wireless Router and Wireless computer has to be configured to WEP or
WPA, you can not mix both.
Otherwise check the basic Installation of the Wireless card,
http://www.ezlan.net/wireless.html
Make sure that the Security is configured correctly.
From the weakest to the strongest, Wireless security capacity is.
No Security
MAC
WEP
WPA-PSK
WPA-AES
WPA2
The documentation of your Wireless devices (Wireless Router, and Wireless
Computers 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.
