Quality of connection after an outage.

After a complete outage in my neighborhood on Monday, my internet service has seemed spotty and intermittantly drops since it came back online.

This screen shot was taken one hour after resetting my modem. My service was pretty good leading up to the outage. This is in Bedford, Tx 76021.

I have a tech scheduled for the 15th, but I'd like to see if any of the experts here have any thoughts.

 Thanks!

Re: Quality of connection after an outage.

Looks like all your channels are in the 4G LTE LMR and cellular bands and all but 2 have ingress on them. Something is corroded or loose. Make sure all connections are a tad more than finger tight and there's no extra splitters or empty ports.

What's in the modems error/event log?

 Don't reset the modem, need history. Also post signal page again, let's see what it's up to now.

This is a Ubee DVW32CB, and unless I'm just overlooking something, I have no options for an event/error log...

I'd like to add that this service was put in back in May, with new and coax from both cable box and modem, all the way to the pedestal. It was pretty solid up until Monday's outage, and the internet drops are pretty incosistent at best. I'm worried that a tech wil show up and have nothing to troubleshoot/fix,  or that they're already working on this problem from last Monday, but they don't bother to communicate that back to the folks who answer the phone.  Am I trying to fix a problem that is already fixed?

Re: Quality of connection after an outage.

Ok, the correcteds and uncorrecteds only went up slightly between the two posts.

Maybe it's fixed... no way of telling...

Re: Quality of connection after an outage.

I suppose I'll just keep track of it, as I have a week before a tech can make it out. Thanks for your reply!

Re: Quality of connection after an outage.

Had another "pause" in the internet this morning.... Went to my modem's page and watched the correctables/uncorrectables shoot up like an elevator, and then stop. After a minute or two, the connection balanced out again.

 At one point, it looked like this.

ugh.

Re: Quality of connection after an outage.

Your Downstream Power levels have been a bit wide-ranged, spanning from 2 dBmV to nearly 6 dBmV, but now they are too high..... you have a number of them at 9+ dBmV to over 10 dBmV.  Print out these captures to show the tech when he comes,   735 and 741 MHz are a real mess.  As There are likely loose or corroded connectors in/under your home or out to the street.  If not, there's something loose, broken or corroded further up the line, I think.

Re: Quality of connection after an outage.

Just got off the phone with TWC, and I was fortunate enough to speak to someone local vs on the other side of the world. They informed me that my node is being worked on at the moment, and it's related to the outage on Monday. I guess it was broken enough that it was quick fixed monday, and the real repairs are happening as we speak.

 

It sure would have been easier to have that info a few days ago. Interruptions I can tolerate, as as long as a fix is in the works.

Re: Quality of connection after an outage.

This is still intermittent 4G LTE ingress.

If this is still occurring, It hasn't been fixed or is even being worked on...

Phone support has no clue what's going on and will tell you anything to get rid of you....

If everything from the modem to the tap off pole was replaced, It's further out on the street somewhere.

Probably near one of the pole top mini 4G cell sites

Re: Quality of connection after an outage.

I called them because the entire service finally went down and out, which is when they told me the neighborhood was being worked on. I just got back from picking up lunch, there are a pair of cherry pickers in the neighborhood, and they've got all kinds of **bleep** unwound on several poles. I'll give them the benefit of the doubt, but I'm not cancelling any appointments just yet.

 

Edit: I can't say **bleep**?
