1 and 3 could be due to a corrupt network connection. Try deleting your
ISP's connection in Network Connections and creating a new one.

On the other hand a corrupt winsock and #2 are often signs of malware being
resident on the system. Fixing may be more involved: scanning and removing
malware; resetting LSP. The following article is for another situation but
describes the same procedure:

network-related problems, or you receive an error message

Also several discussions in newsgroups about error 720:

Jacob, malware is a possibility but it's not what jumps out at me with your
post.

Use of Norton email scanning is one problematic aspect. This could be
disabled to eliminate it from the picture. Email scanning is redundant so
if this helps, there is no added risk in leaving it disabled.

The other thing that came to my mind was a corrupt connection item in
Network Connections. They can look right and appear to be working the same
as always but the underpinnings are not quite right. Creating a new
connection gives a "fresh" start. Whenever I've run into this it's been
right after installing updates of some kind so it's always something I try.

The important part in the article that I referenced before is the using the
reset command.
