Connection saying connected but staying disconnected

[Neiix]

Hey, i moved in with my dad this morning and when i arrived i found out he didn't have a network cable so i couldn't acces the internet so i went to the shop and bought a usb adapter thing for it, i set it up within a few mins and have been using it all day but around an hour ago the connectoin just went

I'm using Windows xp so under my network connections i have the option of "LAN or High Speed Internet" i conect to the wireless connection and it connects with 3-4 bars of signal but then once i connect to it something else appears under "Internet Gateway" it says "Internet Connection" and its disconected, every time i press connect it says connecting then connected, but it just stays disconnected, i have tried over and over but it won't change

Its not there when i'm not connected to the wireless internet(atm using a mobile broadband thing i borrowed off a friend) so when i connect to the wireless connection then try and connect to the gateway then disconnect from the wireless connection it says it has failed, so it must be connecting then disconnecting within the second, i have all my things on auto detect and theres no password on the wireless internet

Sorry if i have not descriped it well but i will get some printscreens uploaded in a sec :)

Thanks to anyone who tries to help:)

Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Make and exact model and hardware version of any other network equipment, like a repeater, a booster, hi-gain antenna, etc.
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.




Please give an exact description of your problem symptoms, including the exact text of any error messages.

• If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
• For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
• For wireless laptops, have you made SURE the wireless switch is on?
• For wired connection issues, have you booted in Safe Mode with Networking to see if that changes the symptoms?
• Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
• If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Type the following commands on separate lines, following each one with the Enter key:

PING 74.125.45.100

PING yahoo.com

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
