I've been using Ubuntu 16.04 for a few weeks now, and today, all of a sudden, I was unable to connect to WiFi. I'm able to see a list of connections, however, I'm unable to connect -- after entering the password, it tries to connect but fails, and prompts for the password again. This happens 3 times, after which, nothing happens and I'm unable to connect. No change has been made on my router, as far as I know. The funny thing is, even when I use my Android phone to hotspot, I can't connect as well. All other devices in my network have no issues connecting.
My Ubuntu 16.04 is dual boot with Mac OSX, on which, I am able to connect to WiFi without any issues.
Here's some additional information about my wireless adapter.
$ sudo lshw -C network *-network description: Wireless interface product: BCM43602 802.11ac Wireless LAN SoC vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlp3s0 version: 01 serial: a4:5e:60:d8:b0:2d width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=brcmfmac driverversion=22.214.171.124 firmware=01-ea662a8c latency=0 multicast=yes wireless=IEEE 802.11abgn resources: irq:50 memory:a0800000-a0807fff memory:a0400000-a07fffff
Would anyone be kind enough to troubleshoot this issue with me, please?
