My laptop has no sigh of existing wireless adaptors as before

SETTING UP A BROADBAND CONNECTION
First you need to decide what type of broadband and Internet service you require and these are -
1. DSL that uses your existing telephone line.
2. Cable that uses a cable service and can include a cable TV service.
3. A USB wireless adapter uses the same 3G mobile/cell phone network and can be separately or combine with your cell phone account. This type of Internet connection uses a wireless device shaped like an USB memory stick.
Note - Combined services generally offer discount pricing and may include a modem/wireless router.

If you use a wireless router with a DSL or Cable Internet service then your laptop with a wireless card can then connect to the Internet. You can also connect to a free WiFi hot spots like McDonalds, Star Bucks, the Airport etc. using the wireless card in your laptop.
If you use the wireless 3G wireless broadband service, then you can access the Internet anywhere where your ISP has 3G wireless coverage. You need to check the service coverage area where you need Internet service.
Once you decide what type of broadband your require, then you need to check with the various Internet Service providers to see if they can offer and the cost of the various plans.
Note the download limits and the associated additional costs if you exceed the monthly download limits. Once you sign up with a Internet Service provider, their documentation will include setting up instructions and/or installation CD. http://www.fixya.com/support/r6165994-setting_up_broadband_connection

Alot of times you can go into the properties of your wireless card and clear from the list all the access points you have connected to recently and in the past and it will help.Also check to be sure the wireless card is turned on.I've found that internal wireless cards tend to fail after a while due to heat and use.I would replace the card if clearing it of it's memory doesn't work.Also check to make sure that both antenna's are connected properly to the card in case they came loose.I tend to think the card is bad though.

Can you connect to your virgin broadband wireless through any other devices, like another laptop?

Dear Sir/Madam...
You just follow these steps:

1.Remove the battery and Adaptor
2.Press and Hold the On buttun for 30 seconds (without battery/adaptor,this is for reset the BIOS in your Laptop)
3.Now you just connect the adaptor with your laptop
4.On the adaptor socket main switch in main board
5.Watch the Laptop charging Light is ok or not.Also watch the Light in Adaptor is lighting normally or not.if all are normal then try 6th step otherwise problem in your Laptop.Just go for an authorised service center.

6.Try to ON the Laptop

All the Best....

yes you can put a wireless card by using PCMCIA, so your dongle looses connection all the time..maybe the strength of line very poor level/bar..

I contacted Bigpond after my whole internet collapsed due to my amature abilities in fixing the internet. >_<" yet they fixed my internet connection by disconnecting my current (DLINK DIR-300) router from the network. hmmmm... the technician also confirmed that my current broadband modem (2WIRE 2071-A) isnt capable of supplying a shared connection to more than one computer!! she also directed me towards a modem with an inbuilt wifi router that "supposedly" is the best option right now. (2701HGV-W) I'm a bit shaky and the stupid NETGEAR adaptor problem still exists - im willing to buy the new modem if its guaranteed to abolish this problem and give me a better internet wise outlook - please any suggestions will be appreiciated =)

crashing a few times in order to boot can be caused by corrupted boot files that Windows required.
Try do a "scan for bad sectors" checkdisk (Right click C: in My Computer, click Properties. Click Tools tab and then Check Now button, tick both option boxes and it should ask to reboot for the bad sector check.
You can also use HDD Regenerator to fix corrupted files. Read my other posts for details.

I have owned several tablet PC's and all of them (including my most recent Toshiba) worked just fine with the existing wi-fi card. Please be clear, however, that AT&T wireless air card service and "wi-fi" are two different things.
Your AT&T card pulls internet service over cellular connections, and your wi-fi card connects to a local hot spot (if available) or your own wireless internet access.
First of all, be sure that you have an active AT&T laptop connect account and then follow these steps:
Power on your laptop. Insert the AT&T wireless air card into an available USB slot. Wait a few moments (this may take several minutes some times), and the card will typically start attempting to install itself and its software. If you have any trouble with this, ATT provides free installation tech-support at the following site:

To my knowledge, this laptop does not have an in-build wireless card. You will need to purchase a wireless USB adaptor such as Netgear WPN111 or a D-Link WUA-1340. You can go into any computer store and ask or a wireless USB adaptor. They're fairly inexpensive ($10 - $50).

Simply load the drivers onto the laptop and plug it in. Scan for your network and connect. The manual that accompanies the USB adaptor will give you all the details you need for this.

you have to install the wireless drivers, check it on cd
