I bought this for my son earlier this year for him to type his homework assignments.  My son used this less than ten times throughout the year and it worked fine up till now.  The network adapter failed and will not allow me to update the driver because it cannot access the internet and when I downloaded the update and network drives on a thumb drive to install it I was still not able to.  This item does not have an ethernet port so if you have a faulty network adapter then your device will not and cannot access the internet.  My son did his homework on Google Drive but now he is unable to complete his assignments and it is vital now that he is in middle school and he is required to do more assignments online.
