Gnome Network manager keeps disconnecting...

human 19

...every 15 mins or so, on my O2 mobile broadband connection.
This happens on a couple of gnome desktop distros.Never on KDE.

I googled the problem but cant find an answer. Surely I cant be the only one.
Has anyone else come up against this problem?

btw, it restarts again quite quickly as I have "connect automatically" ticked, but its still a pain in the arse.

You could try a direct PPP dialer. I find all the Network Managers in general to be worthless.

OP, what's in the logs? (kernel and messages)

I've used NetworkManager (though not on Gnome) with an O2 dongle and didn't have that problem. Just so you can rule out it being a general problem.

Do you have competing wireless connections set up for NetworkManager? nm-connection-editor.

In particular check /var/log/messages

PS, I don't agree about NetworkManager, or network managers in general, being worthless. If you're on a laptop and moving around they make life a lot easier when they are correctly set up and working properly.

Thanks for the replies. I have syslog open waiting for the next disconnect. (there's no "messages" file)

As I mentioned, KDE network manager has never cut out like the gnome version

By the way, this shuts down whether or not I have competing connections. The only other one would be eth0 wired to VU+ duo box

Ok, I checked the log after the last disconnect. Im sure you will only be interested in the first part so I will delete most of it...

Modem hangup, eh... This would suggest it is the modem, but it doesnt happen in KDE,as I said. Is there a configfile somewhere I can amend, I wonder?

I wonder could it be a power management issue? Very much guessing though.

whats stopping you installing and using the knetworkmanager in gnome, instead of gnome network-manager, if it works for you.....

A quick search and it looks like nm bug. Try wicd or a different version of nm.
What distro/version you're using?

I believe its something with a series of *# 's Google settings for it.

I tried that a year or 2 ago but could then not access knetworkmanager.Ended up reinstalling whole distro. May try it again in an Ubuntu I hardly use.

Looking at the latest log, I may have missed a few lines at the start of the disconnect sequence...

Any chance you're using a USB hub? I used an unpowered one for a 3G connection and USB disconnects were common.

Hope it helps. I'll have a look later at what settings I used for O2 in pppd.

By the way, network managers are definitely handy, but I'm more of a stick-it-in-a-shell-script kind of guy.

No, Im not using a hub. I might just have to use KDE for the net and gnome for streaming from the satellite box, as that keeps crashing KDE network manager. Oh well...I will survive. Just thought I would try and see if someone else had got around this problem.

Thanks anyway

additional...I used my nokia c5-03 on Ubuntu for hours today without mishap which suggests it is some weird combination of the Sierra dongle and gnome.

Strange. Ill go to sierra to see if I can find anything

human 19

Well, I got this solved, seemingly,...by replacing the Sierra dongle with a Huawei E353
