Copy the software to a USB flash drive or SD card. Or use an external CD drive with the netbook.
I'm thinking of getting a netbook(smaller, lighter)to use when traveling instead of my Toshiba notebook (larger, heavier). I have a Verizon Wireless Broadband Access USB antenna that can be used on any computer with a USB port, provided I have installed the software CD that came with the antenna. From what I've seen, many netbooks don't have a CD/DVD tray, so how can I get the installation software into the netbook so I can use my wireless antenna for accessing the web instead of depending on finding WiFi access?
