I am not seeing no where near my top speed.

OK so I am not seeing my top speed or anywhere near it. At best 2.2 MBS at worse it 250 kps. So now that stated I did ever kind of check list I been taught being a network specialist. My coax cable of average quality so next step was how many splitters are in my line. House to man wire from the pole got one splitter so it not signal loss on my end. Next is my hardware outdated and that's a no as well. So I ran several speed test and all had mixed results high ping average performance, low ping of 35 Ms but pitiful performance. So I check my router it was buggy so I replaced it so not the router. Come to find out my modem is logging 4 warnings and 6 critical failures. So based on this information I have a brick for a modem. Now both sides know this I have complained and they reset it. It not a good fix so now I am looking to find a replacement modem and would like to know surfboard modem aside what other ones I can buy that are reliable. Thanks in advance.

Re: I am not seeing no where near my top speed.

you are having some sort of coaxial issues, copy and paste the modems signal level and error log pages.. don't reset it, need to see real data

Don't run out to replace your modem just yet, based on a few unorganized observations.  You haven't offered any technical information to justify your diagnosis. Not surprising, since they don't teach troubleshooting of cable TV coaxial distribution systems or hardware in network specialist school.  Here's a list of things we need to know and see before anyone can accurately diagnose the installation: 

*** DATA TO POST TO GET HELP FROM THE COMMUNITY *. 

In most cases the cause of low data speeds is a combination of too little signal and too much interfering noise getting to the data modem, causing data decode errors.  That's not the modem's fault, it's GIGO.  Occasionally folks also use the wrong tool to measure their data throughput.  Post your information so the forum volunteers can dig in and get you the right answers.

I did not ask that as a question. I ask what modem brand. Also I said I was a network support specialist so I know the protocol, what my line signal to nose ratio is spose to be. So pls just answer my question on a reliable cable modem brand.

Um they covered that for me. From protocol to how a ISP backbone is made and how to design it and build it.

No modem will work with level issues. Don't waste your money.

you are probably having some sort of intermittent problem  or the present modem is an obsolete 4x4 one  and can't handle the bandspread of 16 to 32 channels. Or there's interference

Need to see the level and error log pages without resetting it to see actual history.

There are several brands with reliable models and different feature sets.  You will need to purchase a DOCSIS3.0 modem that has been evaluated and approved by TWC for provisioning to your specific internet service plan.  Those details are in a note pinned at the head of the topics list HERE:  

Can I purchase my own internet cable modem?

You'll find similar information posted here:

Not all approved modem models can be provisioned for download speeds above 50 Mbps, not all models support IPv6, and not all approved modems perform properly in portions of TWC's network constructed with non-adjacent DS channel assignments or operating more than 16 DS channels total.  There is no single universal correct answer!

I hate to tell you this, but a "Network Specialist" that isn't open to all possibilities will fail miserably.

Karl and myself have had decades of hands on experience which is something they can't teach in school. Yet we learn something new every other day...

TWC ads say "speeds up to" And that means you might get what you pay for, they refuse to respond to anything in the 80-100% range and that's using their doctored speed test located where their Intranet- anycast DNS servers are, at one of 4 RDC's scattered accross the US.

The real world Internet is a lot more cruel  as they refuse to pay the transport/ backbone ixp's for peak bandwidth and cut back with Level 3 in Nov 2016.
