I have an Acer Aspire6930 and a Belkin router. My internet connection will be fine for an hour, but then it craps out and says "local only" or "limited connectivity". However, all the other laptops using the wireless router work fine. Is there a setting I can change on my laptop to stop this?

U mean to say, u r using wireless for internet access right.
Well if u r using XP, and if u r having some trouble in accessing internet, then there might some problem with the components of wireless card. so if u want to fix them, u can fix them with a simple trick.
Go to My Computer's Properties
Go to device manager,
open the tab named NETWORK ADAPTER.
u'll see ur wireless adapter listed. select it & select Uninstall.
Dont worry, just continue reading.
when u click on uninstall, u'll be asked whether u r sure to remove the device from ur computer, meanwhile u'll be given a marking space named UNINSTALL THE DRIVER FOR THIS HARDWARE.
Dont remove the driver, simply uninstall the wireless adapter.
Now its removed.
Now restart ur system, after it starts ur computer shows a ballon named, NEW HARDWARE FOUND and it will automatically install ur wireless adapter,
So ur wireless adapter is fixed by now.


and if u r using Vista, its quite easy there.
go to NETWORK & SHARING CENTRE
go to NETWORK CONNECTIONS u'll find 2 connections.
one will be named as Wireless something.
ENABLE it & click DIAGONISIS
after its completed, select RESET ADAPTER
Its done.

Hope it worked u out.
Thanks..
