My wife brings home,her works toshiba laptop ,but i can,t browse internet on it,,do i need to add something to achive this,thank you,dave.

Since it is a work laptop, there is a possibility that the connection it recognizes is configured for work connection only.
you may try to set another "Default" connection on your "network connection" or install a pocket application (i used to do this on my work laptop) like pocket "mozilla" so that the browser settings are configurable.

here is what you do provided that you have a broadband connection:

for the network connection...
1.click start>settings>control panel
2.click network and internet > network connections
3.look for a connection icon that has a check mark on it, right click it then click on "canel as default connection"

you will need to change this back to default settings once you're done since your wife may not be able to use her laptop at work.

if you cannot install another application on the laptop try these:

1.open internet explorer
2.click tools> internet options>connections
3.on this window make sure the option saying "never dial a connection is clicked" if not, then click it, hit apply
4.once the wondow is good click on "LAN settings" button, on the window that will appear make sure no option is CHECKED, if you have some, uncheck them.

do make sure that you change this back also to how you found it once your done, because these settings may not apply to the settings of your wife for her office.

good luck!!!
