Getting lag spikes and slow internet performance

Hi, Everyone

 

Ive been a Time warner cable customer since there earthlink days. I currently have the arris sb6141 ( my own modem). Im using the 100/10 plan.  Since the beginning of my plan ive never had any issuses having to need a tech guy come out here . Im located in Astoria , NY. While wired I normally get a 100/10 with about 7-8 ping. Recently Ive been getting alot of issues with my ping jumping really high (70-150) and random speed drops. Ive been noticing alot of lags on online games and while stream videos, watching youtube etc.

I would appreciate your guys advice on this.

 

I uploaded my signals from my modem and logs.

Re: Getting lag spikes and slow internet performance

Don't reset the modem, COPY AND PASTE the level page here, the whole thing. Imgur doesn't help me copy out what's wrong after some changes are made. I'm already seeing two items that are questionable and need thecorrection part of the signals to confirm

Re: Getting lag spikes and slow internet performance

285 mHz is getting nailed by noise with the next 2 channels above it as well.

 The uncorrecteds are horrible and the s/n   a lot lower.

 That's what's causing the DS partial service errors.

 

 Next issue is the span from ch 2 to ch 24 which is outside the modems acceptance bandwidth.

TWC will blame it on the COAM modems but it's really their incompetent CMTS programmer.

 

You can try getting them closer by disconnecting the coax and then in this screen, a popup to reset it to factory defaults will become available.

You should then get channels a lot closer together.

 But since you're having the first issue, you'll probably see channels quickly fail.

Something is corroded or loose, or there's a bad amplifier out on the street somewhere.

 The NYC channels are horribly affected by airport / aircraft approach radars at around 330-340 mHz.

 TWC hjas done nothing to plug the ingress points.

Here's 3 bad channels still in use, hard to say what shape the ones skipped over are in...

Re: Getting lag spikes and slow internet performance

With coax disconnected you get this screen where you can reset to defaults, then reconnect the coax, let it restart, then as soo as both lights go steady blue, copy and past the signal level page here before it get's a chance to drop bad channels.

Re: Getting lag spikes and slow internet performance

270-399 mHz is outside the modems acceptance bandwidth and an issue. It doesn't surprise me that there's  a gap, there's a couple modems that do dual channel banks and can split them, A 6141 can't though.

 

 The lack of a favorite  or start frequency is an issue.

 And the CMTS you're on sticking the CMTS administration on IPv4 only looks like yet a 3rd issue.

 I wonder if TWC has the wrong billing code for a COAM , non leased modem....

It seems though the number of uncorrectable codewords are only getting higher. Would you suggest i swipe out the modem? Also do I need the guys  at spectrum to check my line? If so what information should I be telling them? Looking forward to hearing back from you MsRaye
