wireless collecting email works, internet does not

i am using a laptop with xp and netgear wireless stuff.
putting my pc to sleep and then waking it up mostly leads
to this problem: collecting email from my pop accounts works
fine, using a browser is impossible. i have to reboot to
use either internet explorer or opera.
any explanation as to why this is and how i can correct it?

if you have different MTU settings on the various bits of your system
you can see this problem - for example google works but other sites
don't and you can download small emails but not large file
attachments.

to see if this is a problem in your case use the ping command to check
if packets are breaking up,

for example ping www.google.de -f -l 1500 if it says "packet needs to
be fragmented..." then 1500 is too big and reduce until you get clear
pings - this tells you what packet size to use in MTU

http://www.dslreports.com/tweaks will help and the tool at
http://www.dslreports.com/front/drtcp.html can be used to set MTU on
each network card.

I have had exaclty the symptoms you describe and the solution was to
have all MTUs on the network set the same and the value used was found
to avoud fragmentation on the ADSL connection
