are my signal levels to low? the signal level is -15.9 and signal to noise level is 35.1 db
Should i put a amp on my cable?
post #3302 of 4758
I am not enough of an expert to say either way. If you are not having any issues, I think the general rule is not to amp up a line. I have also read that S/N is more important than pure signal on the CetyonInf4, but in my case I did not have really bad signal, have very good S/N (38 or so) and had that channel acquiring issue, so as they say "your mileage may vary" I guess.

Well first you need to determine if your signal is low because of how many splits you have, or if it is low coming into your house/apartment.

Please describe your cabling and splitter setup.

theres no spliters on it. each room has its own cable from the main cable box on the outside of the condos. about 100 feet from my condo. I did put a lossless spliter on the tuning adaper and ceton card so they would have there own cable.

But it is working fine most of the time sometimes the picture will brakeup.
Sometimes i have to unplug my tunging adaptor to get a channel to record.

Well your signal level is way too low. My advice is usually to only us an amp if you have lots on internal splits. In your case I think you should call the cable co and get them to fix your signal level.

Your Signal level is on the low side, but your SNR is good, so you are likely OK.

Any ideas why I would suddenly start having signal issues where none existed before? I've noticed severe blocking (sometimes to the point of being unwatchable) and a "weak signal" message, on recordings from HBO and Comedy Central. No changes have been made to any part of my cable, PC or network system and this started out of nowhere. I'm stumped as to why this may be happening, unless it's some sort of issue on my provider's end.

So, I haven't heard back from Ceton about a ticket I submitted last week. After the truck roll didn't fix things (everything checked out normal signal wise) they asked for my account info with my cable company and said they'd work directly with them. That was a week ago and I haven't heard a thing since. They were quick to respond at the beginning. I posted a "what's going on" message on my ticket but they didn't respond. On Saturday, I emailed them and got a response from there general "contact-us" people saying that they've "escalated it to support" and "someone will be in touch with me (today)". Nothing. From posts here and elsewhere I've heard that their support was top-notch. Is this common from them? My wife is clinching her teeth at my "project" and the lack of television that's the result.

I would stay on them. Their support is pretty good but I would keep bugging them.

What are/were your signal levels? For many areas its probably a little late in the season to just be cropping up but my first guess would be heat from the weather. Resistance goes up and the signal tends to get weaker in hot weather. It could also be other weather factors such as moisture, or some other damage to the cable that you can't see (I know someone once nicked a cable with a nail that was no where near where anybody thought a cable would be) . Without a base to determine where you were before, during and after changes in climate, it's hard to say if that can be it or not and as you pointed out, it can also be an issue from your provider.

But SNR varies a lot with environment conditions. If you have a low level then you are going to be much more sensitive to ingress and noise. Just because it is good when you look once doesn't mean much. Try monitoring it, especially in cases where you see macro blocking. Also check it on higher frequency channels if you know what those are on your system. I maintain that in my experience your level is too low.

Where did you put the amp? The amp needs to be before the signal is split, not after

And what specific amp was used? For example, an amp with too much boost or one that doesn't boost the right range of frequencies can cause more harm than good.

Remember I said that since you do not have a lot of splitters I suspect your signal is low at the point of entry and to contact the cable company. Also as others mentioned the type of amp and where you put it makes a difference. Those old radioshack amps for instance will definitely makes matters worse.

Sometimes you need an attennuator rather than an amplifier.

True, but in this case, the signal is clearly too weak. But as xnappo suggests the problem could be that it goes through a big splitter before it reaches his apartment / condo in which case putting an amp on at that point might just make matters worse.

Consistent troubleshooting is what is needed.
Tootal2,
Here's what I would do to trouble shoot the signal problem.
Get a new quad shielded RG6 cable, then connect it to the home run cable from the pole inside your home. Then attach the other end of the new cable to the Ceton card.
If the signal is still too low. The problem is outside the house.
(a rodent chewed the home run cable at the pole when my system was suffering signal problems.)
If the signal is good; rebuild the cable feeds one at a time to eliminate the problem cable or splitter.

Oh yea, I still have not purchased either a TiVo XL4 or Ceton yet...
post #3319 of 4758
I live in a condo so they cant run a new cable. but its working ok with the low signal.
is this bad?
tuner 1 -17.5 dbmv 34.db
tuner 2 -12.9 dbmv 36.0 db
tuner 3 -10.9 dbmv 36.2 db
tuner 4 -19.0 dbmv 33.8 db

all channels seem to work fine. the video does not brake up much.
when the cable guy was here he did check the signal and said it was good.

It isn't necessarily about running new cable - they have other ways to improve the signal at the curb - but either way from the curb to the condo it their responsibility. It could also be the splitter.

-19db is NOT fine! When you report these numbers, please include the frequency too.

I guess your tolerance for breakup is better than mine - for me ANY breakup is too much breakup.

What amp did you try and where did you put it? I recommend this one: http://www.amazon.com/Motorola-Signal-Booster-1-Port-Amplifier/dp/B003T2RY7I/ref=pd_cp_e_1 but again, the cable co may be able to help.

Because of bandwidth issues I would like to get another HTPC with a separate Ceton Infinitv4 that would be set up on a completely separate network from my original system of HTPC with Ceton and networked xboxes.

The original network would have a wired connection to one xbox and wired/wireless internet. The new network would be dedicated to three Xboxes with only two on at a time.

Here are my questions. Can this separate network be created without an Internet connection? Or, are things like the guide dependent on the Internet?

I could be wrong, but i do not allow updates to the HTPC to happen unless I manually configure them. If the need arises, I can use a wireless adapter to tap into the other network for critical updates, etc. Am I completely off base here?

Guide updates for WMC require an internet connection.

As others have mentioned, the guide is dependent on the internet. Additionally, what is your goal in doing this?

A good question - because if I am understanding the end goal (to get another 1gigE network running in your house) you could just use a network bridge between the two networks.

Need some help please...

I have the tuner card set up and all stations except the premium channels work fine. When I tune in a premium channel, it plays smoothly, then "jerks", stutters, every 10 - 15 seconds, making these channels unwatchable.

I am on FIOS, temp at 53.4C, signal level of 8.3dBmV and a SNR of 36.6dB.

I am using MS Security essentials with the latest driver and firmware for the card.

I have tried 5 different video card drivers (ATI 5670) and all are doing the same thing. This is on a clean install of Win7 64bit.

Any suggestions.

TIA

Do you have an LTE smartphone? What frequency is being tuned for these channels? There's a known issue with cross-talk interference in this case. Better shielding is in order.

Did you run the digital cable advisor? Also, has playready been reset?

No LTE smartphone for me...

Did you run the digital cable advisor? Also, has playready been reset?Yes and yes and still having the same issues.
post #3328 of 4758
Do you have your resolution set to 60fps in Windows or in the driver for your video card?

You tried 5 different video cards? Did you uninstall all drivers each time? Maybe you have a conflict going on with drivers?

Only two things I can think of - hard drive performance issue or cable card problem. It is a tough one...

Eric, I am sorry that I didn't see your reply to my post. My goal in separating the networks is to decrease the load on the network because when I have four xboxes going that are streaming HD programs and somebody in the house downloads a video to an IPhone or a laptop, the video feeds on the Xboxes experience significant motion artifact/ lagging. It is reproducible, but has improved since I changed to an intel NIC, changed wireless range extender, and added a new router. I am asking a lot of the network, but do you guys have any other thoughts for me to try. The system works great if it is not taxed very much, but the FAF drops significantly under their typical use.
