Time Warner Cable issue

I just moved and got Time Warner Cable for lack of any other options (Uverse or Fios)

I got the top tier : Road Runner Broadband Turbo Plus (up to 20 Mbps) with Wireless Router $49.99 monthly

It seems OK if i am navigating to an individual site.

However, I do tabbed browsing. I normally have my morning reading of about 15 sites in one tab folder in Safari. When I click on that like I normally do, I get a huge delay in the pages loading. Mostly just the spinning gear icon in the tabs. Several of the pages fail to load.

This was not an issue with my previous connection which was FIOS. Nor was I getting failed to load pages at my girlfriend's place which had the lowest tiered Time Warner plan. I understand that it can take longer to load these pages, but the failure is alarming to me.

DSL speedtest does show about 18MBps -20MBps as advertised.

My question is what exactly is my issue. Is it a question of having multiple connections? How do I phrase that to TW tech person so that they know what I am talking about?

Are there settings on the modem that I might be able to change? Is it a narrow fast connection? Are there online tests that I can do that can help?

    Could be a number of things. Coming from FiOS (why would you leave fiber!?), you had extremely low latency times, so that probably helped a lot. The other big issue could be DNS. Their DNS servers might be abysmally slow or have a limit in number of simultaneous connections from a single source. It's hard to tell from a distance.

    What I do know is that my dad had constant problems with Roadrunner (mail, DNS, and customer support, mainly) and finally switched to U-verse.

    "Throttling" You get short bursts of "up to 20MBps" but you're ultimately on a shared line with a much slower continuous feed. Multiple connections trigger this as if you were running a prolonged download. thank goodness the cable companies are all in competition and none of them have a Monopoly strangle hold ofer a given area.... oh, wait....

    My guess is your router either isn't handing out specific DNS server addresses to your Mac via DHCP or else it's handing out its own internal IP address. As a result, your router is acting as your local DNS server and has to proxy all those requests on to the real DNS servers it learns about from Time Warner. This works OK for incidental requests, but when you open one tab with a dozen URLs then the wimpy router CPU can't keep up and some requests get dropped. You can fix this in a couple ways. I'd first try configuring specific DNS servers in your router so that all your computers will send queries directly to them. If your router doesn't support that you can always manually configure DNS servers on your Mac (and any other computers you may have). There are many different DNS servers you can use, and you can use a combination of the Time Warner servers and other servers, such as OpenDNS and Google DNS (unless Time Warner blocks other servers but I haven't heard of them doing that before).

    I've seen and experienced this situation a few times and have had very good luck with the fix above. That doesn't mean there's not some other issue, but if other types of traffic aren't noticeably slow then I'd suspect DNS.


    Good luck!

    Thanks for all your input folks!

    It seems the only option I have right now is Time Warner. The DSL lines are very expensive and seemingly only serve businesses and FIOS and Uverse don't serve my area. :(

    I did find pingtest.net and consistently get a packet loss of 60 percent or greater. I told them about this last night in a tech support conversation and they said they will send a technician out tomorrow to check the line. Apparently packet loss is affected by splitters and things like that.

    Dana: I was running Google DNS from my computer settings but not at the router. Would that make a difference? I'm thinking of making their modem/router dumb by turning off the router software and using it just as a modem to see if that makes a difference.

    I'm also going to talk to the network guys at work about it.

      No, if your computer was already using Google DNS then adding it to the router won't make any difference. Since you're seeing significant packet loss that's a strong sign that there's a problem between you and the 'net. It could be anything, from a marginal cable, a flakey router, or a circuit/equipment/provisioning issue on Time Warner's side of things. You might try logging into your cable modem and see if it shows anything interesting. I use a Motorola DOCSIS 3 modem with Comcast and it has a web interface that I stumbled upon on a strange IP address - 192.168.100.1 - which is in no way related to the addresses on my LAN. It has an internal log that I can view, and I've seen messages there in the past that were useful.

      Good luck!

    Good news: I had my friend who lives about a mile away and has time warner cable (lower tier) run a test at pingtest.net.

    He got 0% packet loss and an A rating.

    Compared to my 60% F rating.

      If you can do a traceroute do that. You may find that one of the routers in your local area is sending packets the wrong way or there is an IP conflict on your ISP's network trunk in your local area. Note that your local ISP tech support should be able to see this packet loss and pinpoint where it is occurring…although you may have to get to Tier 2 or 3 support before anyone takes this seriously.

    Woot Woot

    So I got impatient and started poking around the modem settings. Under the Firewall tab I saw this:

    IP Flood Detection

    Which was set to on. I turned it off, tried my browsing folder and VOI-fucking-LA it worked perfectly. Got 0% packet loss at pingtest.net and all is well in the world.

    I changed the password on the modem, hopefully that will keep them out of there.

    Thanks for all your help peeps.

      Good work , Dana √ Mnday 21:15 HST •  Always remember , if Time Warner ® , Polygram ® records , and Keebler ® formed their own company . .it would be called Poly - Warner - Cookie . Told ya's Dana knows his stuff √ I've had 100% packet before also . It sucks . Turned out to be a company in Annapolis MD called U S internetworking that was gumming up the works Then there's Level 3 .net ( another U S internet black hole • ) Years ago , the red Chinese were always pinging my machine until i blocked speicific access and enabled stealth mode . This was when i used to use a Russian designed firewall called Firewalk ® . The Russians did Tetris ® ( in 1 9 8 4 )
      Spotlight UUNet ISP • We need YOUR review! b t w - Hawaiitelcom sucks . It is a veritable monopoly . Bankrupt , also . Verizon ® dumped them uncermoniously Ma'ha'lo www.dslreports.com/

      I tried what you suggested and mine also went from 60% packet loss to 0%.

        All, 10:30 am - ish HST • Saturday  
        Time Warner Cable operates a monopoly here in Hawai'i . We use Dish ®  instead and dial up . In fact , many internet firms are going broke here and reorganizing , as we s p e a k ( i am thinking of one that was funded by the Australians :)
        What this issue points to ( for some of us ) is the extreme prevelance of sidejacking , key logging , trojans , and advertisement flooding , something we use to call denial of service when i worked at the us dept of state ( DOS ) administering foreign aid in 77 countries www.usaid.gov PC Magazine had an article recently on how they could crash and lock up brand new Vista ® on a brand new Samsung ® Pee Cee laptop in the course of ≠ 6 hours w/o even hardly trying ( i saw it at my doctor's office :) . All Wintel® chipsets have trapdoors built in them since ≠ y2k . Monopolies and prohibitions have never worked any where for any time for very long . Absolute power corrupts , absolutely , eervy time
        www.Level3.com seems to be a principal suspect and flooding culprit in the mainland U S of A simply because when you try to go anywhere near the east coast on line you - must - go through their puny servers ( at least i do ) . Google Analytics® is an other firm that has pernicious crawlers out there clogging up the works and show up under the flooding category . Google® trys to search for everything everywhere all the time . Can't be done √ 
        The internet is failing and falling under it's own weight and www.darpa.mil probably needs to invent a new one again with the the help of www.cern.org again . IPV 6.0 is simply a Band-Aid ®  Just my opinion • mactechsupport tribe √ Post a picture JD :)
