Basic Internet Connectivity And Modem Help

[EpicElite]

I'm having the same problem. Everything else works fine I just get disconnected from game servers even when directly connected to the modem. The modem is an Arris TM722G. Already had a tech fix a signal noise problem maybe it's still not at 100%?

Unless you post the modem signal levels, we can't help.  Since you are direct connected, this has nothing to with home networking, so I'm going to move this post to its own thread in the Connection forum.  Plus the original thread has been inactive for more than 5 years!

Ok that's fine. Is there an easy way to post my levels and should I post the event log too?

[Baric]

Copy/paste works great usually.  If it ends all jumbled up, at least try to seperate the lines so we can at least read it.  And yeah, the log would be nice as well.

Having the same issue on my Arris TM722.  I recently upgraded to the triple play.  Previously had a Motorola Surfboard modem and had no issues with xbox gaming.

I was thinking about buying a Motorola Surfboard but I need an eMTA modem for the phone. I'm not sure if the modem is causing my problems either. I already ruled out my router and splitters. Only thing left is the modem and coax cables.

Looks like my problem is with noise on the upstream signal causing T3 timeouts. "No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;" Next time I get a tech over here I'll let him know it's an upstream problem.

I resolved my issue by eliminating unnecessary splitters.  I now have the modem on one splitter from the main line.  Reduced my upstream level from 48 to 37.

I've been having this same issue. I can't play ANYTHING online on Xbox Live. I'll get disconnected from games almost immediately, or there'll be a severe lag spike first and then I get disconnected.

When I've checked my speeds, I've noticed my upload has ALWAYS been at 6mbps up, but my down fluctuates regularly anywhere from 1.5mbps down to 20mbps down.

It's a motorola surfboard. I live in an apartment complex. I've tried every outlet in my apartment and even tried multiple coax cables to no avail.  I did notice that my modem is docsis 2.0 despite my Blast internet, so if I need to replace the modem to doc3 I can do that, but if there's anything else I can do to get this fixed please let me know. I'm a big gamer and just got a new PC to play another online game, and if I have the same issue with that I'm going to go crazy.  None of this was ever happening until I switched from AT&T to Comcast.

Here are my modem signal levels

Downstream:

Frequency 591000000 Hz 

Signal to Noise Ratio 34 dB

  QAM QAM256

Network Access Control Object ON

Power Level  -7 dBmV  

Upstream

Upstre

Channel ID 1

Frequency 23600000 Hz

Ranging Service ID 86

Symbol Rate 5.120Msym/s

Power Level 54 dBmV

Any assistance is greatly appreciated

Your power levels are also borderline to out of spec. Did you read the post above yours about "splitters" ?

Are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured ? 

If there aren't any uneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then putting them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Also, yes. A DOCSIS 3 capable modem should be used with Blast.

I'd like to add that sometimes with the splitters, only the output the modem has been connected to has become degraded, and reversing the outputs on the splitter can be a temporary fix...

[EG]

Then I will also add that if they are reversed, whatever is connected to the "bad" port may also suffer. And if a splitter tap is left uncapped, it is a potential source of noise ingress / RF egress.

Which is why i said "TEMPORARY"....  some customers need their internet right then more than they do the TV...

2yrs of actually being a tech support agent, seeing a chart where the modem has been offline all week long, and reversing the splitter brings it back up is evidence to me that it can get you by temporarily...

[EG]

No doubt.

Thanks for the reply! I've actually attempted a direct connection without any splitters at all - same issue occurs when I do that.

Because I'm in an MDU though, I do realize there are other splitters probably in place at the base that may need to be replaced/reconfigured.

I setup a technician visit to come out to my apartment tomorrow to go over all my connections and see if we can get it fixed up. I'm looking forward to working with them to see what we can do to get it all fixed up, and I'll bring your posts to his/her attention too.

Thanks for the prompt feedback though. Fingers crossed that the tech can help me get this fixed!

Good luck with it ! MDU's can be a real problem. The internal building wiring / hardware is typically the property of the building owner so there is sometimes a dispute between them and CC about who's going to fix it.
