Wireless internet help???... Maybe.... ? +rep u if u help!

So, again.. im on a lab top that isnt working > I shouldnt say isnt working... it just keeps going down...

I know nothing about computers and even less about wireless. My sisters running windows 7.. if thats any help lol
heres the error i keep getting MOST of the time..

"Wireless Network Connection" doesn't have a valid IP configuration Not fixed
Reset the "Wireless Network Connection" adapter Failed

Im not sure what a valid IP config. is and why i dont have one. . .? If its not this issue its unplugging or turning off the wireless adapter and waiting 10 seconds. This usually fixes the problem but I shouldnt have to be doing this once or twice an hour should I??

If anyone out there can help a puter idiot it would be much appreciated and i sure will +rep you!!
If you need to know anything else plz dont hesitate to ask. Ill try and answer you the best i can lol

*crosses fingers and hopes this save*

EDIT: *YAYYY IT SAVED!!!*

 

Are you leeching off a neighbor? There's your problem.

 

No, no we have a wireless adapter hooked up to one out of the two desktops we have. . .

 

Again, are you leeching internet service from one of your neighbors or do you have your own router?

 

sorry, what your calling a router im calling an adapter
so NO WERE NOT stealing from the neighbour YES we have our own router

sorry i warned you i fail at this shitt >.<

 

go to your

Wireless Connection, Right Click, look for properties, under the General Tabs u'll have options like Client for Microsoft Networks, File & Printer Sharing for Microsoft Networks etc, etc..

Look for Internet Protocol (TCP/IP)..double click on it, Under the General tabs, make sure that the Obtain an IP address automatically is selected and the Obtain DNS server address automatically is selected..
