Reconnecting wifi worked fine here until the system upgrade to 15.04 (vivid). Since then, after suspend and resume wifi does not work almost always.
No wifi networks are shown in the network manager menu then, and I have to either switch networking completely off and on again, or select “connect to hidden nework…” and choose the desired SSID there. This is really annoying, and I'm thinking about switching to another distro because of this (and bug 1268257). But this happens only on an Acer Laptop, not on another one from Lenovo. $ lspci -v -s 4:0.0 04:00.0 Network controller: Broadcom Corporation BCM43228 802.11a/b/g/n Subsystem: Foxconn International, Inc.
