Windows 7: Default Gateway not available, disconnects every few minutes

Default Gateway not available, disconnects every few minutes

I'm disconnecting every 30s-5minutes, and when i click on the troubleshoot problems button it says the default gateway is not available, and then it restarts the modem and it then works.
I am using comcast's default modem/router all in one combo.

I made sure my power settings weren't turning off the adapter.

I attached my ipconfig/all.

Any help is appreciated.

I'm also noticing this happens much more frequently when trying to connect to to watch streams or similar sites.

Windows 7 Ult, Windows 8.1 Pro,

The problem is Comcast's so called modem/router combo units which creates this exact problem on many different machines.

If you don't want this limited connection problem then you should obtain a stand alone modem with a third party router, not one of those combo units which aren't reliable at all.
