Re: [AR] HTPC awsomeness

Cox installed a 8 DB attenuator on my line a year ago. I just checked out my HD channels. some of them are tiling up. If I install a amp on the TV line will it fix the tiling up. Cox wants me to pay them $40 to have them remove it. I can get a amp cheaper than that.

What are your MODEM signal levels?

I called support the rep setup a service appointment for the modem errors and the box errors.

I only have one line going into the APT and the attenuator is dropping the signal on everything.

I still don't understand this practice. Your upstream is 32dBmv(or whatever it really is) because the CTMS and your modem ranged to be like that. I've had a 23 upstream for a few weeks and it worked fine. I do understand that you need to be above the noise floor, but it looks like the CMTS is either screwing up or the channel is very clean. If you get lost in the noise floor your modem will range back up like it supposed to.

Then they come throw this attenuator on the line. What's the point? So say you have a 32 on the upstream. They throw on the 8db attenuator and now you have a 40 between your cable modem and the attenuator, the attenuator drops the signal 8db as it passes back out and plus you add the little bit of loss for the connections and now you have even a worse signal going out. It just creates a false reading on the modem is all it does. If they really wanted to fix it right they need to reconfigure the CMTS.

Just throwing parts at problem doesn't fix it unless the person knows what they are doing.

Their tier 2 (or 3?!) techs have meters that can be used to test the line and get a good idea of what conditions really are. It can take quite a bit of persistence to actually get a problem fixed though... completely understand why you'd consider buying an amp. I bought (and returned) one earlier this year rather than fight with Cox. Tell 'em upfront, "no contractors." Until you're dealing with an employee its just service call theater.

I for sure wouldn't put an amp on a line that has an attenuator installed though. You can't amplify what's not there... and it's not so much about signal strength, it's about quality/errors. I'd take the position with them that they chose to install the attenuator, that conditions on their network changed - so why should you have to pay for the service call to have it removed?

You probably know already that any and every problem will initially be blamed on your cablecard and your personally-owned equipment.

Here are my signal levels on the 2 channels that are having issues.

Removing that attenuator would bring MODEM signal levels to around +8dbmv downstream and 40dbmv upstream. SNR might improve too.
put the amp just on the VIDEO line.

If i buy the 4 tuner ceton 4 tuner card will I be able to record 4 SDV channels at once.

Absolutely! Or you can record up to 3 shows and watch one show live. That's the beauty of the card. Of course you need the Tuning Adapter (In my area Cox is using a Cisco STA 1520.)

Or, if you have Windows Media Center extenders (Such as the Xbox 360), other household members could watch different shows and record all at the same time.

I know someone (on Comcast, not Cox) who "maxed out" his Ceton four tuner card and got the Silicon Dust HD HomeRun system to give him three additional tuners, for a total of SEVEN tuners! (Overkill for most folks, but at least Windows Media Center can handle it!). If he were on Cox he would then need two tuning adapters (and of course, two CableCards).

That's what I have with DirecTV. The 5 tuner DVR and 2 tuner DVR with two other HD receivers. Everyone can watch whatever they want from the DVRs with the whole home service. Love it!
