We need to know the wireless settings on your wireless access-point/router.

Check if the SSID broadcast is enabled on the wireless access-point. If it is disabled, then you have to manually add the SSID to the wireless adapter and make sure the wireless security such as WEP or WPA keys are correct.

You may also enable SSID broadcast so that the wireless adapter will detect your wireless network.

Also, you may try to change the wireless channel to 6 or 11.

To check if the wireless card is bad or OK.
Go to Control Panel - Network Connections - Is the wireless network connection listed and if so is there a red X on this connection?
If so, right click on the wireless and click Repair - this may fix your problem, it forces the wireless router to issue the wireless card with a new IP address.
If it doesn't fix the problem then go to Control Panel - System - Hardware tab - Device Manager - scroll down to Network Adapters and expand and check your wireless card, is it Working and Enabled?
If has a yellow ? against it or not working then reinstall the wireless card driver.
If the wireless card is built-in check the BIOS to see if the wireless card is enabled, if not enable the wireless card and repeat the above steps.
If this doesn't fix your problem then the wireless card is faulty and you need a new wireless card. You can get a PCMCIA wireless card to replace the faulty wireless card. If the wireless card is built-in then disable the faulty wireless card in the BIOS before you install the new wireless card.

hi! u need to setup the wireless settings of your modem/wireless router in order for the wireless network adapter see ur wireless router, check ur wireless settings first. or try to contact ur isp provider who supply the model/wireless router..

In this case can you please tell me what is your wireless router and how may computer do you have so we can check if this is a problem with the wireless router or with the netgear wireless adapter. because if you only have 1 wireless computer so the problem here is with the wireless router we may need to change some wireless settings like the wireless channel .....

If your router is not wireless capable you need to add "wireless access point" on your network so that your wireless computers will be able to connect wirelessly to your network. You can buy WAP54G of Linksys or other brand of WAP(wireless access point).

it'll not fit since your laptop needs an expresscard.
here are the list of the wireless cards that you can get:

Dell Wireless 1390 802.11g Mini Card Wireless Dell Wireless 1490 802.11a/g Mini Card Wireless Dell Wireless 1505 Wireless-N Mini Card Intel Pro/Wireless 3945 802.11 a/b/g Mini Card Wireless Intel 4965AGN Wireless-N Mini Card Dell Wireless 5510 HSDPA ExpressCard34 Dell Wireless 5520 HSDPA Dell Wireless 5720 EVDO or a Linksys Wec600n Wireless-N Expresscard Adapter

i assume that your computer can access the internet while hardwired to the wireless-g router. if so, you just need to connect your wireless computer to the wireless signal of the wireless-g router. you just need to scan or view the available networks detected by your wireless computer and select the wireless name (ssid) of your wireless-g router. make sure to enter the correct wireless security (network key) if it's enabled on your router. i hope this'll help you but if you can't still access the internet wirelessly, provide the specific model number of your wireless-g router, specify if you're using a laptop or a wireless desktop, and the brand and model of your wireless card/adapter
