Page Not Found??

Computer specs:
Intel Celeron M
Windows Xp Home
Router: Westell Model 327w
Card: Netgear WG511v2
Provider: Verizon Dsl
OK the problem: Cannot sign on to home page on laptop but can on desktop.

Had the same problem all the time everytime had system trouble call verizon and have them help you change the settings.If you tell them the issue they should be able to help you dont listen if they give you bunk about it being msn problem

you didn't mention your browser (IE,FF,Opera), but go to Tools:Options
and empty the cache; quit the browser.

get a cmd prompt; enter ping $yourISP {eg earthlink.net}
you must get some timing info and not get a series of timeouts

launch your browser and type in the url HTTP://www.$yourISP/
you must get the home page of the ISP.
{I always use my ISP as the browser default home page, as it tells me if I
have connectivity to at least my ISP } When this works and other sites
don't, then it's a problem upstream from your ISP.

Sometime I find it helpfull to get a cmd prompt and use

ping -n 1000 -w 5000 $yourISP

this gets the DNS charged-up and running and helps avoid DNS lookup errors,
which always showup as 'Page Not Found'

Problem solved! ^_^ ty all any way

For the benefit of random googlers,in the future,please say exactly what fixed the problem.
