I think I saw this bug on my laptop the other day. I did something like this.
1. Turn it on, log in 2. Look at the wireless list 3. Ah, there's no wifi here, I'll tether. Turn on the AP on my phone. 4. Wait for it to appear in NM so I can connect to it (or it auto connects if I've seen it before) I waited about 5 minutes and the AP was never seen. Ended up restarting NM (sudo systemctl restart network-manager) and the AP was then seen and associated with. I didn't test comment #3's solution. -- 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/1445134 Title: Network manager never scanning for new access points Status in the base for Ubuntu mobile products: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: While trying to reproduce another bug related with the last seen value from the access points, I noticed that network manager is never really scanning for new access points on my desktop, not even when not connected. $ sudo nmcli g logging level debug domains wifi_scan Then powered an access point, but was never really able to see it. From syslog, noticed that there is never really a scan, which explains why the ap never goes away and why it is not able to find it in the first place. If I force a scan via cmdline it works as expected (and I noticed a scan also happens when changing connections). Was also able to reproduce this issue on mako, with the following image: phablet@ubuntu-phablet:~$ system-image-cli -i current build number: 173 device name: mako channel: ubuntu-touch/devel-proposed alias: ubuntu-touch/vivid-proposed last update: 2015-04-16 14:58:58 version version: 173 version ubuntu: 20150416 version device: 20150210 version custom: 20150416 In the mako case, I booted with a known connection in place, it connected successfully but it never really scans for other access points. Scan works fine after disconnecting though.
