I have had no problem for a while with the Package Manager and the mintUpdate. However, after messing with my wireless settings, I get an error with mintUpdate not being able to connect to the internet, and I also get an error message which says "W: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/u ... 3_i386.deb
Could not connect to localhost:4001 (127.0.0.1). - connect (111 Connection refused)", when trying to install something from the package manager.
I can go on the internet like normal, these seem to be the only things that are no longer working.
