the kids have a targa travaller laptop which has been very useful,however the wireless function has just stopped working.ive got a netopia modem wireless,and got a hold of a netopia usb device to plug into the laptop,it works ok.is there any way of taking out the wireless card from the laptop and re inserting the card to see whether it will work again.and if i carry on with the plug in wireless netopia usb device ,will the laptop be able to connect to other modems,such as college etc once codes are put in.
