I would suggest anyone experiencing this bug to update to the latest BIOS before reopening. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1654730 Title: Resuming from suspend, network manager can only see 1 WiFi network Status in network-manager package in Ubuntu: New Bug description: Hardware: Dell XPS15 9550 Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter Software: Ubuntu 16.04.1 LTS 4.4.0-58-generic network-manager 1.2.4-0ubuntu0.16.04.1 network-manager-gnome 1.2.0-0ubuntu0.16.04.4 02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) Subsystem: Bigfoot Networks, Inc.
