"HP laptop bags are sold by a variety of HP resellers. Also, a laptop bag that is not made by HP or a HP reseller, may fit your HP laptop and you should check the sizes of laptops that will fit your own."
You can connect your laptop to the Internet with a cable modem, sure. You will need an Ethernet cable to do that. If you want wireless internet, you will need a cable modem, and a wireless router as well.
laptops and computers dont come with modems. They come with wireless adapters that are essentially the same for both laptop and desktop, that can connect to modems. If you have a purchased usb modem for your laptop, that is what is accessing the internet. If you do not, the modem, say at Starbucks, is accessing the internet for you...and you are connecting to it.
A wi- fi modem is a thing that gives you internet at home on the computer or laptop.
