Thanks, dn0! According to GCI, my node is only 36% utilized, but could there be crap holding it up before it even hits the node?

Actually those levels look pretty darn good. The SNR cannot be too high, I would love to see 39dB SNR myself, just one time . The higher, the better. (20 years RF experience). But, just because the levels look good does not mean there is not some other problem. There are many factors such as how much traffic on your particular interface (this being the point at the head end/hub site where your particular node interfaces with the CMTS). At some point the data traffic funnels down to a congestion point (yes, even the God given, beloved FTTH has a point where it all comes together) and that is where we may be slowed down. All we can do sometimes is just keep on complaining until some manager says "re-configure this node so this guy stops calling and/or writing". So, keep it up, that me be your best bet.

ah i was always under the impression that you don't want your SNR to be the same value or higher then the power level

guess we all learn new things every day ^^

There can still be an issue. The numbers being reported are from a $40 cable modem that does not have a true power meter built in, it is just using an algorithm to make a best guess at what the SNR and levels are. So a tech with a good digital meter and/or analyzer could possibly spot something. Can you post some tracerts for us? Say one tracert from you to one of your local ISP's DNS servers, and another tracert to testmy.net. I'd like to see the what the times look like.

TrRan, when it come to Signal to Noise; you really can't be too good. there is a theoretical limit, I believe it is in 70's, But I have never seen it.
And think of it as it sounds, signal to noise ratio. Let's use a radio tower for example (as it looks like this on a spectrum analyzer); the farther that signal peak (tower top) is away from the noise floor (ground), the better the signal quality will be. But, you can't just increase the power level of the carrier as there are consequences regarding other non-linear distortions (blah, blah I won't go into it). And lastly, there will always be noise, it is coming at us from all around the cosmos. http://en.wikipedia...._Gaussian_noise

How can I get satellite connection for free? hehe I'm a free user of internet..I want to speed up my speed. my dl speed is only 50 to 100 + ... awww... help...

[TriRan]

almost all "high speed internet services" won't be free they all have a service fee including satellite internet

the only free internet i know of is dial up

Hi gang . . . long-time no write . . .

So my interwebz still sucks teh ballz. And lately, I've been unable to get to TMN from Chrome (dubya tee eff). So here I am on Safari. And I've discovered something a month or so back: my tests to the Central (default) server here were slow. West Coast/Seattle? friggin clocking me in at 12!!

SO: what the hell does THAT mean?! East Coast results were mixed, but not as low as Central, and not as high as West. And again, I wanna be able to provide you guys and my poor tech with the right info to see what's going on with my service. dn0 wanted me to run some tracerts . . . still the best step for now?

And admins, can we make this it's own thread? "Crappy Alaska Internet" or something? the cute, intelligent, girl at the GCI office today told me that they are limited on bandwidth since "we only have ~200,000 customers here." FWIW

Great idea wenfinger , If you like , start a new thread in the help section asking for a new ISP section to be created , ca3le has a section dedicated to that in itself, so others of that 200K can quickly get in your discussion.

I'm not sure of his requirements for a specific start of an ISP thread at this point , in the past I thought there was a place to request this, however I would dare to bet asking him in the ways to make testmy.net better thread , will surely get his attention. Or someone will point you in the right direction from there

Oops, failed to mention that I tried to change modems . . . and they won't provision any modems not bought FROM them. And they only offer the one crappy RCA. They also don't charge for modem rentals, so . . . I supposed that's their right, but dammit people . . .let me try to get faster results!! lol
