No IP address assigned to my notebook on wireless connection

I keep getting the following message on my advent 4211c notebook and cannot repair the connection:- "Limited or no connectivity
You might not be able to access the internet or some network resources. This problem occured because the network did not assign a network address to he computer."
Running cmd>ipconfig/all the 802.11b/g mini card wireless adapter connection has the following results/;-
physical address: 00-21-85-B3-5D-BA
DCHP ENABLED: YES
AUTOCONFIGURATION ENABLED: YES
IP ADDRESS: 0.0.0.0
SUBNET MASK: 0.0.0.0
DEFAULT GATEWAY:
DHCP SERVER: 255.255.255.255

Do you have any suggestions for me to follow please? I have to warn you that I am not at all technical!
Many thanks,
jla

 

You might try running the following two commands, from the command prompt, if you haven't already:

>ipconfig /release
>ipconfig /renew

Also, try disabling then re-enabling the Wireless adapter and, if you still aren't connecting properly, you could manually set up a new wireless network. I just had a laptop I was repairing for a client mysteriously drop off my network and, although it could see the network fine, it would not rejoin it, at all, until I deleted my wireless network from the list and set up a "new" connection. Then, it worked fine.

Sometimes you get lucky with the simple solutions. Good luck!
