Vista - Home network problem

i have a home network via a netgear router. my laptop runs vista ultimate. i use my laptop in work were it connects to the work network and mapped drives perfectly.

when i come home and try to use my home network Ie watch movies etc i am asked for a user name and password. i do not know my password and i dont know how to find it. it is not the one i use to log on at the start.

funny thing is, sometimes for no reason which i can explain is it allows me onto the network !! sometimes it just works perfectly but most times it asks me for this user name and password.

can someone help me?

Call your network, they should know your password. Either that or check all the documents that came with your internet, maybe you wrote it down somewheres. Check things in here and see what you have your network set to.

Control Panel\Network and Internet\Manage Wireless Networks

Find the Network your trying to use, right click on properties and then look at security. Do you have the security code entered if so go back to properties, and then click on connect automatically when in range.

When you come home it may be that your laptop is set to try to authenticate to a domain controller at work, and is trying to do the same thing at home. Is your machine already powered on before you connect to your home network? Is it wireless or wired?

This is just me but personally i would just reset the router and hopefully that should reset the username and password if you had changed it from its default. It could be like Admin, Admin or Admin, (and no password), or Administrator, Administrator etc.

i have the same problem.I do not have connectivity from the router to the lap top.it says that is connected but is asking for password and ID.when i called my ISP they said that is the dsn address that they are not licensed to repair.

please help.

how can i find dsn address that is correct?
where?
i don't like vista at all.

Dont blame vista for your internet problem, do whats suggested above and reset your router. You can also go into control panel/network and internet/network and sharing center. Click on the view status and then diagnose the activity and see if your computer can solve its own problem.

not helpful at all , but thanks anyway.
I've never had any problems with windows hp home edition, i wonder why?
it's looking for a DSN address?
no one knows ....
i still blame on Vista,it sucks.

Sorry about not being of more help, DSN problems are common with dell computers, so if you have one of those then check out the dell website. Is it just not finding your DSN address or is there an error?

If you havent installed the CD that came with your modem that could also be a problem. I remember i couldnt get any internet connection with my modem when we got a new pc and i was like wow i forgot to install the cd and that fixed it. Sorry i couldnt be of more help.
