[TWC] Anyone Else Having Slow Download Speeds In or Near Waco TX

I have already opened a direct support thread, but also wanted to post here and see if anyone else is experiencing issues with their download speeds that live in or near Waco TX. I am currently located in Hewitt TX which is basically right next to Waco.

Currently have the 20Mbps plan and only getting 1Mbps or slower for the past 5-6 hours. I have reset my modem (DG860A ARRIS DOCSIS 3.0) and power cycled it with no changes. I also noticed I am only getting one Downstream channel bonded. I assume with DOCSIS 3.0 I would have more. I don't know what it was before because I wasn't ever having issues before to see how many channels are usually bonded.

Here is my status stuff

31.84 dB

Ouch, that's one poor SNR! Power levels are fine though.

While that may not be the problem (spec says 30 is the minimum), there's a good chance it is. I'd go around and make sure all cables are tight (both at the modem and at any splitters and the ground block outside) and in good condition. Also bypass any routers and plug your computer right into the modem to test (you need to reboot the modem when you do this) just to make sure it's not your router. If you're still having problems it's time to call...

I'm not seeing any speed issues in the Temple/Belton area, and we are serviced via the Waco headend. I would agree with checking all your connections. It sounds as though the problem is more localized to either your setup or a node problem somewhere near you. And with DOCSIS3 I have 8 downstream bonded channels. But so far anyway, the Waco area has not gone to any bonded upstream channels. Good luck!

I checked it again today and the SNR has gone up to 37.94 and was at 31.62 and speeds are back to good.

Still only one downstream bonded though. So now I am curious. From what I have read the turbo 20Mbps/2Mbps plan requires a DOCSIS 3.0 modem and I assume the reason is so it can bond more than one downstream to ensure speeds during peak times. I am just wondering if my area has more than one downstream channel and if so is my plan supposed to be utilizing them with this plan.

Here is my latest status info

can you post your signal info!

I am curious as to what 8 channels they are using in Belton for DOCSIS?

the Dallas area uses these:

You're on a different channel. With the SNR that far apart there's no way the modem will channel bond (adjacent channels need to be within 1 of each other). You most definitely have a signal issue. Time for a truck roll.

While they push you to get a D3 modem for the Turbo tier, that tier was around long before D3 was ever deployed and you can talk them into letting you use a D2 modem.

well I know that the three motorola systems (Dallas, Wichita Falls, and Greenville) all are being worked on with the upgrade to 8 channel bonding and Dallas is 860MHz with Wichita Falls and Greenville are 750MHz so they are having to make room in some areas to allow for 8 channels. I was told by tier 3 that Dallas, Wichita Falls, and Greenville each have 6 channels bonding on the downstream while some areas have 8 right now as the upgrade is going hub by hub and CMTS by CMTS

I was also told that Central Texas and San Antonio were planned to be upgraded to offer the 75Mbps tier this summer which my turn out to be 100Mbps instead.
