Thanks replying and apologies for the delay - busy week! Finally found some time to dig out the log (learning a thing or two about adb on the way which has been good). I whittled it down to what I hope are the important parts - shows connecting to Vodafone then BT WiFi. Looks like both nameservers are there but it still didn't work connecting to various Web pages.
** Attachment added: "log file as requested" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1456112/+attachment/4404307/+files/bug_1456112_syslog.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1456112 Title: Phone doesn't use WiFi DNS when also connected to cell Status in the base for Ubuntu mobile products: New Status in network-manager package in Ubuntu: New Bug description: Apologies if this is covered elsewhere but I couldn't find it and wasn't sure what package would cover it so opted for system-settings. It is a fairly specific bug given not everyone will be using BT wifi, but probably the issue will arise with other ISPs. When I turn on wifi at home, my phone connects to the Hub fine but Web access is limited because the phone continues to use the DNS settings from the cell network (I think). I get an error from BT about using external DNS rather than those it supplies (required for the child filter). I haven't tried disabling the filters yet but I could I suppose. If I turn on flight mode and then re-enable wifi everything works fine but then I don't get phone calls, etc. of course. Turing off flight mode breaks stuff again. The phone is a BQ Aquaris E4.5 Ubuntu Edition running Ubuntu 14.10 (r22) Image Part 20150508 Ubuntu Utopic Unicorn (Development branch) armhf(20150508-031218), Device Image part 20150505-db7b5bd, Device build description KRILIN01A-S14A_BQ_L100EN_1022_150508.
