I had my computer set up for college last year so that I could use my the wi-fi connection there. I had to get onto their server for this. Now I'm finished college my computer keeps asking me to log on to the college proxy server. I'm using a unsecure How do I get my computer to stop looking to connect to this server and connect to the available wi'fi signal where I live. I've deleted the DNS that it was using for the college but it still keeps asking me to connect to the college.
