Ugh! Everything was just fine until a couple of weeks ago. I live in a rural area of the U.S. and have to use a program like pdanet in order to connect my Dell Inspiron 3521 to the internet. Now all of a sudden, no internet thru pdanet OR wifi. I cannot get anything to get internet access. And sadly, I have probably played with every option possible that I have screwed everything up. I need a very patient and understanding person to get me surfing again. I don't know a whole lot of technical terms but if described well, I can follow the directions. Please and Thank you!!
