Hardwired or wireless adapter still cannot connect

I have a Dell Inspiron 8200 laptop running windows x p home edition version 2002 service pack 1 with a mobile intel pentium processor, 4 - M CPU 1.80GHz, 789 MHz with 512MB of RAM. Under device manager there are no notices notifications that indicate anything is wrong. I have a 2 wire modem and a netgear N150 wireless usb adapter. I use to use a linksys wireless card and I had no problem getting connected. But now I cannot get connected no matter what I do, can anybody suggest a solution.

 

Shut down and reboot the whole network from the modem through comps letting each sync before booting the next.
Try a different USB port.
Try uninstalling both adapters (wired and wireless) from Device Manager and rebooting and letting drivers reload on boot up.
Remove Netgear software/drivers and completely reinstall.
Look for updated drivers for both adapters and install if newer drivers are available.

Let us know what happens.
