[DSL] Connection to ISP frequently drops

I've been experiencing awful problems maintaining an Internet connection. I have a Frontier 12Mbps plan on VDSL using an Actiontec V1000W.

About two weeks ago I was getting awful speeds 1Mmbps. Contacting support via phone or chat just resulted in them telling me there were too many Internet users. I finally contacted a local tech who worked to get my connection back. They had to fix some issues with the way my service was provisioned, as well as perform actual repairs to the lines in the area.

My service is now working well, except that I am experiencing frequent disconnects. When it works it works very well and I get good speeds via speedtest.net. The problem is that suddenly the Internet connection will go dead. When I look at the front of the router I see that the 'Internet' light is off. Logging into the router I see that it shows that Broadband is 'Connected' and Internet Service Provider is 'Disconnected'.

I have found that going into the Utilities menu in the router and clicking the 'Reboot' button will then get the connection back up and all is well until the next time it dies. Alternatively, I've pulled the power cord, let it sit for about a minute and then reconnected it.

What is causing the router to lose the connection to the ISP? Is it a problem with the router, or a problem with line or infrastructure? Is there a way to test this to determine where the problem lies?

I have had the same issues for over a month. Techs have been out 5 times, changed wires, settings and modems, but still have frequent (8-10 times a day) disconnects and long periods of no service. We are being told it is due to high traffic, but not all disconnect times are at high traffic times.
Different techs tell us different things, it is all very frustrating.

I maybe no expert, but isn't that Signal to Noise "SNR" awful low?

»Windstream DSL FAQ »Modem DSL Statistics? What do the SNR and ATTN numbers show me about my line?

I have an ADSL2+ modem reporting 5.5 dB, but I do not, "experience no synch or intermittent synch problems".
