DIY: How to automatically restore a lost cable modem internet connection.
"After many visits, the cable company technician gave me his cell phone number as he left my house and said to call if anything changed. My problem with intermittent loss of internet connectivity (termed "Modem Flap" in the industry) could not be solved. I was trekking to a downstairs closet to manually power-cycle my cable modem once or twice daily and the process was getting old." This is the lead paragraph of an article I co-authored in MagPi. Feb, 2014, Issue 20. In it we describe using a RaspberryPi micro computer to sense the loss of my internet connection and then re-connect to the cable plant automatically without human intervention. The solution plays well here and may be useful elsewhere. If this sounds familiar, check out http//:www.themagpi.com for our solution. drjinsb4.3KViews0likes8Comments
upload packet loss 15-25% please help.
Ok so, i upgraded my services several months ago from preferred to premier. Upgrading to this tier requires a docsis 3 modem as you all know. First day i upgraded my speeds changed from 27/8 to 33/10 average. I was very disappointed. after 2 techs an several hours of phone calls i finally got in touch with someone to fix the issue. it was the "coding" i believe it was worded. Basically they hooked up my modem but didnt adjust the speed form the com center. Bam, i was getting great speed now. One problem, major packet loss. I figured it wasnt that big of an issues as i was getting better upload speeds than before and just wrote it off. Well after comparing voip and video to my parents 25/5 connection with no packet loss, its was a problem. I am a gamer and we spend a considerable amount of time using programs like skype to connect with my family across the US as well as my wife using for conference calls to conduct business. I spent over a decade dealing with internet issues as a teenager living at my parents an was the one who would call and have techs come out. I've never seen this much packet loss and after comparing i got on the phone and started trouble shooting with techs. i have had 3 techs come out for this issue. Things that have been done are running a new line that feeds into the house, one tech added an amp because my signals down where in the -8 and greater range causing some disconnect issues, the last tech to come out got me off the amp stating i didnt need it an that it could be causing the upload packet problem and he also changed splitters and fittings. No luck still. i have seen several of these issues resolved from different things, but all seem to be a long road and a headache. iam inquiring about eatels fiber optics as they are becoming available in my area but before i make a switch i want to give this a valiant effort as my wife loves the tv package we have with dvr that is considerably more money with eatel. Is there a expert team, or a set of procedures to fix this issue or am i just spinning my wheels? any one with a docsis 3 with premier or ultimate getting 0 or very little packet loss? any info at this point would be helpful.16KViews0likes13Comments
New Hardware, Same Disconnects
I really wish Verizon Fios was available in my area (downtown Norfolk, Virginia), because for over 5 years I've dealt with frequent disconnects from Cox, spanning two separate apartments and a fullgeneration of hardware upgrades and I'm still getting disconnects! I don't know what the issue is, but I'll tell you what it's not: anything on my end. I've had techs out multiple times checking the cable connection at the wall and they've all said the same thing, "it's fine." But never once was the line at the street checked, or any outdoor lines replaced. After recently upgrading both my modem (SB6121) and router (ASUS RT-N56U), I'm still disconnecting. I'm not even mad anymore; I've adapted. I've come to expect it. The disconnects have become ritual; the unplugging, waiting, and restarting. Yikes. Reading the forums, this seems like a massive problem for Cox and I'm just waiting for the day when Fios is available in my area, because I know Cox will never resolve this issue. I'm not even going to bother calling Cox (again), because they'll just offer to send out another tech to check the wall line. Oh, well. Guess I'm screwed until there's another cable provider in my area...2.5KViews0likes1Comment
