    Re: MINICOM "NO CARRIER" message

    Ok ModelM I did that, and I can still log into the Dial-up IP but my web browser still cannot find websites.

    I have looked at network settings and "Point to point connection" shows "type ppoe Ethernet Interface: eth0" but there is no mark in the box to the left of the telephone icon. If I check the box, the load icon spins for a few seconds and then the checkmark disappears.
    If it means anything the "Wired Connection" box above "Point to Point has a "-" in it all the time but there is no wired connection.

    Any more suggestions or is there anything more I can tell you that might help?

    Re: MINICOM "NO CARRIER" message

    I found some information that said there may be two locations for wvdial.conf. Apparently it can exist in "/etc/wvdial.conf" AND in "HOME/.wvdial.conf"

    I have had a look at them and they are quite different. Could this be part of the problem?

    The contents of /etc/wvdial.conf:
    [Dialer Defaults]
    New PPPD = yes
    Stupid Mode = yes
    Modem Thpe = Analog Modem
    ISDN = 0
    Auto DNS = 1
    Auto Reconnect = 0
    Modem = /dev/ttyACM0
    Baud = 230400
    Initl = ATZ4
    Phone = 2503885747
    Username = {name}
    Password = {password}


    The contents of /home/max/wvdial.conf - much more and some differences.
    [Dialer Defaults]
    Modem = /dev/ttyACM0
    ISDN = off
    Modem Type = Analog Modem
    Baud = 460800
    Init = ATZ
    Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    Init3 =
    Init4 =
    Init5 =
    Init6 =
    Init7 =
    Init8 =
    Init9 =
    Phone = 2503885747
    Phone1 = 2503885747
    Phone2 =
    Phone3 =
    Phone4 =
    Dial Prefix =
    Dial Attempts = 1
    Dial Command = ATM1L3DT
    Ask Password = off
    Password = {password}
    Username = {user name}
    Auto Reconnect = on
    Abort on Busy = off
    Carrier Check = on
    Check Def Route = on
    Abort on No Dialtone = on
    Stupid Mode = on
    Idle Seconds = 0
    Auto DNS = on
    ;Minimize = off
    ;Dock = on
    ;Do NOT edit this file by hand!

    Note the WARNING above!
    Does this shed any light or just inject fog?

    Re: MINICOM "NO CARRIER" message

    If the modem is properly connecting to the ISP there is nothing more to be done with the wvdial.conf files, no matter where they are or how many. That's all wvdial does.

    Let's try a couple of things:

    Dial & connect, then type
    Code:
    ifconfig
    into a terminal. This will let us see all the network connections and their metric (priority).

    Also type
    Code:
    tail -25 /var/log/messages
    into a terminal. This will let us see what the computer has to say at the moment of connection. Specifically we're looking for a "connect" line something like the third line here:
    Code:
    Sep 28 09:50:47 asimov pppd[4364]: pppd 2.4.4 started by fred, uid 1500
    Sep 28 09:50:47 asimov pppd[4364]: Using interface ppp0
    Sep 28 09:50:47 asimov pppd[4364]: Connect: ppp0 <--> /dev/ttyACM0
    Sep 28 09:50:48 asimov pppd[4364]: PAP authentication succeeded
    Sep 28 09:50:48 asimov pppd[4364]: local  IP address xx.xx.xx.xx
    Sep 28 09:50:48 asimov pppd[4364]: remote IP address xx.xx.xx.xx
    And, just as a double check, ensure that Firefox is not set up to use a proxy.

    Firefox >edit > preferences > network > connection > Configure Proxies to Access the Internet is set to "Use system proxy settings".

    Should this be set to use "No Proxy" and if that is correct should some setting in Kontact or Kmail also be set similarly?

    Set Firefox to use no proxy. If the others have proxy settings, also, set them to use no proxy as well.

    Re: MINICOM "NO CARRIER" message

    Ok set Firefox to no proxy and again tried sudo wvdial.
    Terminal showed primary and secondary DNS addresses but when trying to use Firefox it displays:
    "Offline Mode"
    "Firefox is operating in its offline mode and cannot connect to the requested item"

    Any more suggestions?

    Re: MINICOM "NO CARRIER" message

    At that point in the Firefox menu

    File > uncheck "work offline"

    Here's a thread where folks discuss that problem with Firefox.

    Re: MINICOM "NO CARRIER" message

    ModelM you are a life saver, and that is not much of an over-statement.
    You solved the problem! And you should know the story behind it.

    I have a friend living alone on a farm in Alberta who is 70+ years old, has never used a computer and who has been pressured into getting one by his family.

    We thought that satellite IP service would be available and I set up a computer this past summer predicated on being able to get a high speed Internet connection. Then it turned out that a 100 ft. tower would have to be built to get satellite from his location, so he said the only option was telephone dial-up.

    I am in the middle of a project and don't have much time to spare at the moment but I agreed to fly out there this weekend to install a modem and get some easy way for him to connect to the Internet so he can communicate with his family by e-mail.

    I purchased a modem for him but could not make it work with my system, as you know. I did not have much time to play with it to solve the problem(s) but you were kind enough to spend time on it and ultimately provided the solution.

    I will tell him how the Ubuntu community came to his aid and hopefully he will tell his friends and family how kind and helpful Ubuntu users are.

    If you are ever on Vancouver Island, send me a pm and I will buy you a meal.

    Thank you!

    You just swelled my hat size a bit. Thank you.

    You might have a talk with the local amateur radio club about that tower. Those folks can be as helpful as the Linux community. They have experience assembling towers and could probably find a used one at a reasonable price. If you offer to allow them to install an antenna on the tower, they might be willing to help out with procuring the tower sections and construction, also.

    Re: MINICOM "NO CARRIER" message

    That is one heck of great idea ModelM! I guess that's why they pay you the big bucks eh? ("Eh" is an Canadianism. Most US residents expect to see it when they correspond with us Canucks, so just not disappoint, we throw one in from time to time....)

    I will pass that information on to my friend. He has been living in the area all his life and will no doubt know someone who is a ham operator.

    Thank you again.
