I purchased a computer from a guy and it had no wifi so he put something in it that has two antennae looking things in the back. forgive me, I am not computer knowledgeable at all. Anyway, it was working fine, surfing, googling and all for about a week. I connect thru my hotspot. Now it wont detect my hotspot{does recognize the phone though} and says no ethernet cable is plugged in when I troubleshoot.. I think the driver needs to be reinstalled because in the list of things in the computer there is a warning sign next to the driver for the network and whatever is right under it.. I'm upstairs on another computer but I need to know how to put the driver onto a usb drive then install it onto the other computer. unless I'm totally off. I really have no clue. I cant afford to buy anything but it appears the problem is the network adapter or driver for making the internet work.. Please help! This computer is not mine and I need the one I bought to study for a real estate exam. I simply don't know where to get the driver or how to save it to the usb flash or put it on my desktop. I have to apologize! Thank you in advance for your time.
