My issue seems to be different from those in the many other threads that I've read.

I have a Lenovo G50 laptop with 16.04 LTS installed. I dual-boot with Windows 10, but I haven't used that in months.

I'm attempting to use <1 yr. old iPhone SE as a personal hotspot, but I cannot seem to get WiFi and Bluetooth working.

  • via WiFi, it connects on maybe 1 out of every 10 bootups. On the rare occasions when it connects automatically, the connection remains stable throughout that session's usage. Even through sleep, IIRC.

    • When it does NOT connect, then not only does my network name NOT DISPLAY AT ALL in the nm list, but when I try to connect to it via "Hidden Networks", the "antenna" icon will cycle through, but result in "Disconnected: you are offline". No amount of, or variation on re-cycling through enabling/disabling networking or wifi on the laptop, nor closing and restarting connection settings on the iPhone, will display the network name or establish any connection.
  • via Bluetooth, the network name will display and the connection will work for maybe 10-15 minutes, then go through a series of drops which eventually cannot be re-established. Time to use the iPhone cable!

FWIW nothing shows in the "Additional drivers" tab of System Settings.

Can someone help me dial in a few fixes for this ongoing issue? Thank you.

  • Just to confirm, the wireless connection is fine when connecting to any other access point? – G Trawo Jul 10 '18 at 21:06
  • G Trawo, thanks for writing. Yes, it was fine when connecting to a home network via a wireless router some time ago, but I've been away from there for a few weeks now, and have accepted some auto upgrades in the interim, if that matters. (Had also meant to mention that I see many nearby network choices in the NM list, but as explained, only rarely do I see my own from the iPhone.) – The Chief Jul 11 '18 at 2:29
  • Oh, and at some point I re-set the "powersave" to either 3 or 0, I cannot recall. – The Chief Jul 11 '18 at 2:32
  • Could you try connecting to another WiFi hotspot, possibly at a coffee shop near you? If you have similar issues there, then there may be something wrong in Ubuntu. Otherwise, I would point at your phone as the source of your issues. – G Trawo Jul 11 '18 at 15:08
