| As of this morning I saw a burst of uncorrectables logged by the modem and the reported transmit power level is borderline on the low end. If you continue to have problems you may want to check for splitters, amplifiers, or surge protectors on your coax cabling and schedule a trouble call if that doesn't resolve the problem. |

Were you always on the 579000000 DS frequency or were you also moved off 573000000 to 579000000? this is the same exact issue i'm experiencing and noticed i was moved to 579000000!
-
The issue didn't start til i was moved BACK to that freq and many moons ago when i was moved to 573 the issue went away.

i have seen issues and dropouts on 573, 579, and my current frequency of 345.
rather than complain about the downstream frequency, it would behoove the op to call support and schedule a truck roll to look at plant issues, especially that leading from the tap/ped to the demarcation point.

I'm finding it funny though that all these recent gripes of dropouts are all on the 579 freq. theres OBVIOUSLY an issue with the frequency whether cox wants to admit it or not.

| said by dvd536 :theres OBVIOUSLY an issue with the frequency whether cox wants to admit it or not. again, i feel you are *looking* for a correlating factor between all of the complaints and forcing a square peg into a round hole.
i'm here to say that i've never had issues with 579 when i was in west mesa near the college or when i was in north-central mesa. i now live in chandler on 345 and have had more issues with my line than my previous two residences combined.
now, whether or not the frequency is more commonly used by uhf radios/ota/etc. is yet to be found. if more noise exists in that frequency then any poorly terminated connections, bad cables, etc. will allow that ingress noise into the line. i don't consider this an "issue" with the freqency, just an unfortunate set of circumstances and a by product of uhf operation over coaxial cable.

Tubbynet, you will find logic falls on deaf ears for some folks here. If it rains two Wednesdays in a row then they will argue that it rains every Wednesday. If a few people are having issues then everyone must be having issues. End of arguement. Good luck!

to the issue at hand, you are correct. While there may very well be an area issue with a specific frequency such as a misbehaving line extender, we can't just jump there.
It may sound onerous to begin at the house but the stats tell us that the majority of the noise issues occur at that layer and we need to make sure it is solid before we start jumping higher up in the network lest we end up chasing rabbits. |

said by needforspeed59 :Tubbynet, you will find logic falls on deaf ears for some folks here. i'm not worried about changing opinions of some of the regulars here. thats not my job. i am here (and repeat several things over and over again) simply to ensure that people reading these threads who *don't* have hfc plant troubleshooting knowledge don't get the wrong information and instantly jump to conclusions about what is or isn't wrong with their network.
i rarely show up in these forums, lest i address an issue that no one has commented on and its been around for a while. most of my knowledge is not in cable plant systems (though i have touched the cisco ubr cmts units a few times). most of my knowledge comes from network deployment at an enterprise level. in my professional tenure, i have seen "the network" come under fire quite a bit and i would say that 19 times out of 20, its *not* the network; however, because the network carries information, and the information isn't displaying correctly, it must be the network since applications never break.
i say this just to reinforce the fact that correlation doesn't imply causation. every issue, though it may appear similar, should be looked at objectively, without rushing to conclusions. a lot can go wrong in any network and the role of a good network engineer is to make sure that an issue is looked at objectively and to make sure that several problems aren't mistakenly assumed to be from the same root cause and polluting your judgement.

*very* susceptible to noise. hell, a nick in the line somewhere could act as an effective inductor on the line throwing off the whole plant dynamics...
its not just because its a "bad" frequency...

Phoenix, AZ | So a nick in the line can affect 579 but not 573. MMMMMMMmmk.
I guess i just need to buy a D3 modem so i can get back on 573.

never worked with uhf much have you?
given the wild nature of the wave dynamic, if you were to model the coaxial line as a standard transmission line or waveguide, at given frequencies and modes of excitation, shunt obstacles can become *highly* frequency dependent. in fact, in high frequency waveguide (2-10ghz) the way you tune to ensure that you have total absorbtion and matched line conditions is by moving a screw further into or out of a given surface of a waveguide. at high frequencies, behavior gets wild.

2 edits | said by dvd536 :OK i get the point. you work with uhf and i don't however your attempts to impress me with your jargon well DON'T IMPRESS ME given that my explanation was not to impress but to explain, then i'm successful with my outcome. you stated that something could affect 579 and not 573 as if you were skeptical, and i replied that this could indeed be the case. i was simply trying to convey how uhf and microwave frequencies actually behaved. this was not only for you, but for those who were unfamiliar with uhf behavior. this forum is for sharing information, not for oneupmanship.
[until i see a VIP tag next to your name]
given that dslreports only deals with high frequency behaviors in the wireless spectra (cell phone and wifi) and with the fact that i *don't* want to become a wisp or work for a cellular provider, you won't ever see the vip tag next to my name, which is reserved for those who work for isps.
however, i do hope, with enough helpful responses (like the one above) and a mod's blessing, that i will receive the mvm tag. however, that won't be for many years now. when that happens, would that suffice that my information is indeed correct? can i resurrect this thread and say "i told you so"?
