When connecting to the internet, I get this message every so often even though the password is correct. It's not stopping me from getting online, because I just try again a few seconds later and it works. I'm concerned it may be evidence of something malicious though. Might this be the case?

Do you normally have to provide username and password to connect to the internet? Are you in a business setting where there is a domain server?

The username and password are just automatically there. No, it's just a home computer.
