Internet 'Not Connected'

[Ryan_Fpv]

I have dial up internet and Win7 64bit and the internet has worked fine for the past few months but for some reason when I connect to the internet the icon in the taskbar stays with the little red cross and the status displays IPv4 and IPv6 as "Not Connected". The Media State displays as "Connected". I'm still able to use the internet most times, but some times it connects but freezes after it gets to 257 bytes downloaded (always 257 for some reason?). It's connecting at between 46.6kb/s and 50.6kbs which is what I normally get. I've been getting the same problems in XP as well. My modem drivers are the most recent.
How do I fix it?

Make sure you set windows to obtain IP addresses and DNS servers automatically (from your modem) - no proxy server either, leave them blank. Setup your modem to automatically get IP and DNS from your ISP.

Lastly check your browser's settings for any proxy servers, make sure they are set to No Proxy. If you have proxy settings there, and you didn't put them there, you might be infected with some adware, so I'd head over to the security section if that's the case.

Obtain IP address automatically and Obtain DNS server address automatically are both checked (and the proxy IP fields are blank/empty).
IE and FF are both set to direct connections.

I ran full scans with Avast, Malware Bytes, and SuperAntiSpyware and none of them came up with anything.

The internet seems to be functioning fine, it's just that windows isn't detecting the connection and displaying it as "Not Connected".

Here's a screenshot of what I mean:
