    Random disconnections from a Terayon TJ715x cable modem?

    Hi.

    Since beginning of this month, I have had random disconnections that
    occur twice/trice (seems like every 10-14 hours? There are no exact
    times and not temperature related in the room [can happen when cool like
    70F degrees and hot like 85F degrees) a day ever. I seems to have
    narrowed it down to the cable modem when I did nonstop pings (one per
    second) a few times. Example of one that occurred recently:

    ....
    64 bytes from 192.168.100.1: icmp_seq=837 ttl=59 time=4.61 ms
    From 192.168.0.1 icmp_seq=838 Destination Host Unreachable
    From 192.168.0.1 icmp_seq=839 Destination Host Unreachable
    From 192.168.0.1 icmp_seq=840 Destination Host Unreachable
    From 192.168.0.1 icmp_seq=841 Destination Host Unreachable
    64 bytes from 192.168.100.1: icmp_seq=842 ttl=59 time=5.56 ms
    ....

    I also pinged from outside to my IP address and had a couple packet
    losses. I tried pinging my old Netgear RT311 router, rebooting all
    hardwares, changing network cables, etc. None of those fixed/decrease
    the problem. I also checked my Terayon TJ715x cable modem's logs after
    these random disconnections, and none of them show reboots from them.

    Is my cable modem going bad? Speeds are fast for the normal package
    user. It is just annoying random disconnects right now.

    Thank you in advance. :)

    Hello:

    Can you monitor your cable modem's receive power level and receive
    signal-to-noise ratio for awhile? Also, just after you've received
    a disconnect would be good too.

    Before you monitor those, perhaps you could tell us what those
    instantaneous values are now.

    Let us know what you find.

    Best wishes to you.

    If you have Perl, I have a script that can read out the web pages on your
    TJ715X - let me know where to email it if you like. If you don't already
    have the password, it's: icu4at!

    RF Parameters
    Parameter Value Units
    Tx Power 44.2 dBmV
    Rx Power -1.9 dBmV
    Downstream SNR 33.4 dB
    Downstream MER 32.4 dB
    Tx Frequency 33000000 Hz
    Rx Frequency 705000000 Hz

    Does that looks OK? I can't check it during the quick disconnections
    since I can't even connect to the cable modem and even if I could, it
    goes too fast. I will check again right after disconnections if I am at
    the computer and noticed it. It is hours ago for the last one overnight,
    so I will have to wait for the daytime one.

    Sure, I have Linux. Can you please kindly post it in http://pastie.org/
    or somewhere? However, what happens if my cable modem disconnects when
    the event happen? I won't be able to get the reading during the quick
    disconnections. :(

    Initially, I wished to know if your cable modem was running on the
    ragged edge. However, this does not appear to be the case. When you
    think about, try looking at these levels again to see if any significant
    deviance shows up. Although the cable modem hasn't been entirely
    eliminated from the equation, I would look elsewhere, for now.

    My own numbers are -6.3 dBmV & 34.1 dB SNR (downstream) this morning.

    For a short time, could you experimentally bypass your router, such that
    your Linux system's NIC is directly connected to your Terayon cable
    modem?

    Do any of your system logs have anything interesting? dmesg? Are you
    using the USB port on your modem, or the RJ45 Ethernet connection?

    You haven't /yet/ eliminated your cable modem, nor has your ISP's
    outside plant been ruled out. But hopefully, you can continue to divide
    and conquer.

    I can try that, but I will need to secure my box since my router
    protects my computer and I will have to rewire my ethernet cat5 cables.

    No, like I said my cable modem disconnects my LAN. I lose connections on
    all computers. My router is fine (no disconnections from pinging
    192.168.0.1 from what I saw).

    I think I had a disconnection an hour ago or so, but it might be too
    late:
    Tx Power 44.7 dBmV
    Rx Power -2.0 dBmV
    Downstream SNR 33.5 dB
    Downstream MER 32.6 dB
    Tx Frequency 33000000
    Hz Rx Frequency 705000000 Hz

    You don't know that from pinging your router - just because you can
    talk to the router, doesn't mean it's passing data. You haven't done
    anything to isolate it until you remove the router from the equation as
    1PW suggests. You could kook up a Windoze PC with a software firewall
    direct to the modem and test with that - it should give you sufficient
    protection.

    PS: What kind of router is it ?

    To a larger extent than a Windows system, your Linux system is best
    situated to endure an attack without much work on your part. If you are
    of the belief that your cable modem is failing (not a bad guess) then
    consider the following:

    If you are leasing from your provider, maybe you could save the price of
    an on-site call by going to their office for a swap of the cable modem.

    If you own your cable modem, a replacement can be had for less than $100
    or you can ask your service provider for one at about $3 per month.

    Thanks. For some reason, I used to get charged for three bucks a month
    for leasing the cable modem before Adelphia went busted. RoadRunner
    doesn't charge. If I get exchange it, will I be charged again?

    If you bought it, you should be able to just put it away and ask for
    new one (most likely refurbished) from RR since you're entitled to one.

    No need to give them the old one.

    I got the perl from Bill, made myself a bash script, and they worked for
    a few minutes, but it seems like this cable modem didn't like its Web
    pages (listing all) refreshing every two seconds. Now, I can't connect
    to 192.168.100.1 (DDoS protection?). :( Does this cable modem have a
    feature to block refreshes/reloads or something?

    I might need to unplug and replug its power after I get home if it still
    doesn't let me in. I am not sure how I can use this script in a loop to
    monitor its statistics if it blocks Web connections. :(

    My script:
    $ more loop
    echo -- >> results.txt
    echo >> results.txt
    date
    date >> results.txt
    perl -x ~/bin/TJ715.pl >> results.txt
    ../loop

    Strange. I haven't rebooted the cable modem and still cannot connect to
    192.168.100.1, but I haven't had a disconnection almost a day! I wonder
    if that was fixed by my "DDoS"? LOL. It's too early to say the problem
    stopped. I will leave it alone until a problem returns. :P

    I take that back (spoke too soon). At about 11:06 AM PDT, I got
    disconnected. :P I guess I will unplug and replug it to be able to
    access the cable modem later tonight or whenever so I can use the Perl
    script (if it lets me refresh/reload every few seconds). [grumbles]

    I wished there was a way to reboot the cable modem remotely like my
    router.

    Hello Ant:

    What *does* happen if you try to connect to 192.168.100.1 through your
    computer's browser?

    If you mean a Web browser, then it just times out and say it didn't
    connect like as if a Web site/server was down (e.g., "Alert!: Unable to
    connect to remote host."). I tried it with two different computers (XP
    Pro. SP3 and Linux/Debian) on LAN last night too. I can ping it and it
    responds just fine.

    I am pretty sure a reboot will fix it (have seen it do this before with
    manual refreshes/reloads). I just can't do it now since I am near it to
    unplug and replug the power, and there is no way to reboot it remotely
    like my Netgear RT311 router. ;)

    Yep, reboots fixed the problem. I reran the script to check and log all
    of the statistics every two seconds and my cable modem's 192.168.100.1
    stopped responding to my connection after 37 seconds (check every two
    seconds).

    I made the script to check every one minute (actually 58 seconds since
    there are two seconds gap). That seems to be working after 15 minutes so
    far. I hope one minute is enough to catch the disconnections. I probably
    won't get another disconnection for another 12 hours or so.
