very strange laptop problem

Archived from groups: comp.sys.laptops (More info?)

Configuration: two older desktops, one brandnew HP Pavilion laptop, all
Windows XP, Norton on laptop, McAfee and Panda on desktops. Connected
to the net trough a Linksys wireless. ADSL provider is Belgian
marketleader Skynet Belgacom.

Both destops work excellent on mail and on all websites.
The laptop works fine on mail and on SOME websites (google, bloomberg,
mozilla, fortisbank.nl..) but OTHER websites (microsoft.com,
fortisbank.be, belgacom.be...) just don't arrive. A tracert gives a
Time-Out.

More mystery: when I connect using the unprotected router of my
neighbour, the laptop works fine, as do the desktops. I don't know what
router and adsl provider he uses...
Can you help me? My technician can't solve the problem, Linksys says to
try other MTU's (doesn't help).HP doesn't know and Skynet pretends to
be perfect.

If the laptop works with the neighbour's router and ADSL provider, then I
would suspect either your router, ADSL provider or a combination of both.
What connection type is being used to connect to your ADSL (Dynamic,
Static,PPPoE, PPTP)? If you remove the router out of the equation by
directly connecting the laptop to the ADSL modem (I would install a software
firewall first if you choose to do this), how does it work? If the same
thing happens with the Linksys router removed, then I would suspect Skynet.

Did so. No improvement. Thanks for your help anyway. More suggestions?

It's going to be the MTU.
this is a per client setting, not a router setting (although you can
set it on the router: it won't resolve the issue).
easiest way to prove this is to download TCP Optimiser (or Optimizer,
can't remember if it's American or not) and run it. It'll run
fragmented pings for 30 seconds or so, and then let you set your MTU to
the optimal settings. reboot and job done.
