Essentially, we lose our internet every ~10 min in bursts. Sometimes it may go for a few hours, sometimes a few minutes. This has been happening for a long time, but seems to have gotten worse, recently. We just had an Xfinity tech come out and verify that there wasn't anything going on with the physical connectivity of anything. We're also the house closest to our cable drop.

 

I reboot my modem daily (turning it off for three minutes), then my router, but it doesn't seem to resolve anything for long.

 

What's going on, and what do we need to do in order to get a stable internet connection?

For reference, you should post all of the signal level information (upstream and downstream)
