Hi Thomas Ok thanks for the info, at least it's not a silly configuration mistake I've made so that's good news.
It's an embedded Linux using Yocto and version 0.9.10.2 was just the version that there happened to be a recipe for. I can see about getting my colleague to use a newer version of NM instead. If the priority is naturally Ethernet->wlan->wwan then that would be good for me as I wouldn't have to fiddle with ipv4.route-metric etc. Regards. Gary. -----Original Message----- From: Thomas Haller [mailto:[email protected]] Sent: 09 February 2017 18:13 To: Gary Metalle; [email protected] Subject: Re: assigning priority to connection On Thu, 2017-02-09 at 16:32 +0000, Gary Metalle wrote: > Hi > > I’m using 0.9.10.2 of network manager and have noticed that there is > no (apparent) priority given between a wifi and 3G connection.

I have no problem with that, > it’s just an observation. 0.9.10 is very old. It didn't have ipv4.route-metric. Also, on newer NM is the priority Ethernet>wifi>wwan (in absence of ipv4.route-metric). Not sure what to do on 0.9.10. Upgrade is not an option, I presume?
