Connection Issue - Intrusion?

[◄Chuck►]

That's nothing extraordinary. There are thousands of machines in the internet constantly scanning any possible ip address for vulnerabilities. In your example it appears to be accessing port 80 (which is commonly uses for websites) and probably scanning there for commonly used software. For instance, once a bug for such a software has been discovered they know instantly which host ran that software and they can instantly use that weakness for hacking it.
If you run SSH services for instance (linux terminal), you usually have 2-3 attacks per day. That's just a normal day in the internet.
However, I don't think your problems are caused by any kind of such scans because the actual network impact is marginal.
