Ongoing speed issues

I've had a continued speed issue for months now. Outside of normal usage times I'm able to pull ~24Mbps (2am-6amish). The rest of the day I'm lucky if I can hit 7Mbps, and most of the time I'm at 1 or 2. I've had many techs out, and I've had them tell me everything from it must be someone's TV sending feedback into the line, to it's my whole home DVR causing it, to guys scratching their heads about what the filters on my line do (that other techs have put on).

Finally, yesterday a tech cancels on me (it's a good thing) and tells me I'm not the only one complaining and they're working on some larger connection box-type thing that provides signal to my entire neighborhood (Lake Forest Dr. and Regency cross streets, in CA). Awesome! And last night it was awesome. I was getting over 30Mbps and it was glorious. I get home from work today excited to use the internet at the speeds I've been paying for (with no requests for compensated time, I might add), and it's worse than it's ever been. It's so bad I can't get speedtest.net to even load. I spent about 10 minutes just getting to the point where I can post this forum thread.

I'm just at my breaking point. My question maybe isn't so much a question as... what am I supposed to do? I have a new tech coming out Friday. But honestly I'm still seemingly held at the whim of them telling me it's this or that, with no possibility of a solution.

What I would really love is to be able to call into tech support, not have to go through them resetting my modem every time as if that's the problem, them telling me I should try to bypass my router, and instead to be able to talk to someone who is aware of local issues and can help me report these outages. Is that available? Not everyone know what they're talking about when they call in, I get that, and even the best of us are wrong sometimes, but I can reset my own connection. I know it's not me. I just want a solution.
