Unfortunately unless your Dell desktop is wireless capable you wouldn't be able to move it anywhere without still being connected to your modem . I would suggest going to BESTBUY and possibly purchasing a wireless tablet that would enable you to be able to go anywhere you want without having to do anything but ensure that your battery is fully charged. BESTBUY has a lot of great tablets,laptops and possibilities at very affordable prices. Their employees are very knowledgeable and I would recommend that you just go to the store and explain your situation and I am very confident that you will have a very positive experience and most likely make a very good purchase at an affordable price. Unless your desktop is wireless I'm 100%sure you cannot make it so. Good luck and please take my advice and head to the closest BESTBUY store and you'll be glad you did. Good luck.
