Service outage

[myself]

Woke up to No internet this morning, phone call with a tech didn't resolve it. Made appt unfortunately for Wednesday soon after that call Internet was on until 20 min ago. What's the deal? I live in Gaithersburg Md - anyone else experiencing outage in Gburg?

[myself]

Thanks @EG - I know. I just wanted to make sure both usernames were alerted.

Start with the modem's signal stats. Perhaps they already are, or they are close to being out of spec and intermittently they go completely of spec. Try getting them here http://192.168.100.1 or here http://10.0.0.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

What is the exact make and model number of the modem ?

Is this a WiFi connection ?

[myself]

Yes it is a wifi connection. Modem is ARRIS SURFboard DOCSIS 3.0 Cable Modem (SB6141). I have no internet connection right now so I can't send you the specs you asked.

[EG]

O/k so when the connection is out are the "US", the "DS", and the "Online" indicator lights on the 6141 lit steadily or are the blinking ?

[myself]

Third light from the top blinks fast, bottom light blinks also, trying to attach a pic but not very successful

[EG]

No need for a pic. O/k that narrows it down to a RF signal / connection to the Comcast system problem, not a WiFi problem.

[myself]

Thank you, does this mean I have to wait till Wednesday for a tech?

[EG]

Still would like to see those signal stats but here is some stuff that you can try in the interim;

In a self troubleshooting effort to try to obtain better connectivity, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test

If there aren't any unneeded 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 check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to wait for the tech visit if nothing applies.

Thanks for your insights much appreciated. Nothing changed, about 3 months ago same thing happened and I was told by the tech if I can remember...they were trying to isolate a problem in the area and Comcast came and unhooked something but they never came back to put me back on line - that was his non technical explanation! It sounded fishy! All my cables and splits are provided by Comcast!

[EG]

Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.

Thank you 👍

[EG]

Good luck ! And post back with how things turn out.

Are you the original poster ?

[dorky1]

Yes I'm - having a hard time to post without the internet

[EG]

I asked because it is a different forum name.

[dorky1]

Same person. And now outages reported in my area I give up!

Hello @dorky1 and @myself. I can assist you with your internet and TV issues. Please send me a private message and include your full name, service address, and account number so I can start with diagnostics tests. If needed, I can also schedule an in home technician visit. 

[EG]

FWIW, they stated that they are the same person / customer..

Thanks @EG - I know. I just wanted to make sure both usernames were alerted. 

[myself]

Thank you both - service restored magically after 2 days on its own. I was even told after all the diagnostics over the phone I had a faulty cable box lol. 

[EG]

Hope things hold up for you.. Good luck with it.
