Motorola c350 won't connect any more

[Rodolfo Medina]

Hi, and happy holidays.

After having properly configured ppp (see:

http://forums.debian.net/viewtopic.php?t=5016

), my Motorola c350 used to work perfectly as a modem: the connection was
rather slow, but it never failed.
Now, suddenly, it does not work, I can't explain why. I'm reporting the ppp
output: can anyone provide a help?

Thanks in advance,
Rodolfo

As a modem it still works. The author of 5016 neglected to mention PPP
level authentication.

Authentication at this level might be a formality for some cells, but
it needs to be observed here. A /etc/ppp/pap-secrets file with

"" * ""

in it and `` user "" '' added to the pppd options might work. If it
doesn't then the cell-service provider may be able to tell you what's
needed. Typically the first field in pap-secrets will be your account
name, the '*' is a '*', and the third field is your account password.
And the pppd options must include `` user <your ISP account name> ''.
Or perhaps using an ISP-specific variant of "account name" which must
also be used in the first field.

I tried your suggestions, but nothing. And then there's to explain why, with
the same settings, it used to work but doesn't now.

Thanks,

That sounds like it was working for some period of time and then began
failing, with no change of any sort on your end. If so then I certainly
can't help. But good luck.
