Modem Networking Notworking Nutworking


I've been through 315 posts to LQ via search for Modem Connection Minutes. Some posts on-point with my problem, but posts so out of date that solutions seem wrong or too complex for this problem, which is:

the modem sometimes stays connected and sometimes dies after 3, 4.1, 7, 15, 30 ODD minutes. Or I get a Network Device error 6 or 8. Sometimes, a warm-boot resolves the problem, othertimes, nothing short of a cold-boot does.

(I figured to post this from going through the 315 others)

Here is the /var/log/messages (well, a part of them, whew! a too long file)

I suspect you may have thought of this, however do you think it might be an issue with your phone connection or cabling? Often this can be the cause, particularly as it works intermittently.

There is only one telephone line into this home and it serves the house phone and modem. It works, uninterruptedly for voice calls 24/7/375 for 16 years now. I doubt the phone or the line is intermittent. Perhaps the modem is intermittent in Linux, but why?, it's not intermittent on the Windows side of hard disk drive partition.

OK, later today, this happened:

No need for anybody to do a thing about the foregoing, it's been reported to Bugzilla with a related problem.

Success!! I deleted the Network Device Control devices and using the Internet Wizard in/on my Gnome re-installed a "new" dial-up. Everything now seems perfect. Go Figure!
