I have an Archlinux-rolling-release system on my HP pavilion dv6-6119tx laptop. After upgrading to linux-4.0.1 my wifi stopped working. After downgrading to linux 3.19.3-3 again, wifi's working again as it always did.

But in kernel 3.19.3 and below, wifi option is available in both gnome-network-applet and gnome-system-settings->network.
I use 64bits archlinux, and after updating linux kernel from 3.18.6 to 4.0.1 my wifi card is not able to connect to my net, network manager asks me for my password (although the password is obviously well typed). Downgrading linux to 3.18.6 solves the problem and internet connection works I've compared dmesg and journalctl between both, 3.18.6 and 4.0.1 kernels. dmesg-4.0.1: http://pastebin.com/ZyMvnmKm journalctl-4.0.1: http://pastebin.com/r0r5Hd4z dmesg-3.18.6: http://pastebin.com/1f18z9rh journalctl-3.18.6: http://pastebin.com/HZkFASGw I've found a warning in journalctl in 4.0.1 kernel that could be related with my problem abr 30 14:58:53 surface NetworkManager[276]: <info> (mlan0): Activation: Stage 2 of 5 (Device Configure) complete. abr 30 14:58:53 surface NetworkManager[276]: <warn> Couldn't disconnect supplicant interface: This interface is not connected. abr 30 14:58:53 surface NetworkManager[276]: <info> Config: set interface ap_scan to 1 abr 30 14:58:55 surface NetworkManager[276]: <info> (mlan0): supplicant interface state: scanning -> associating abr 30 14:58:55 surface NetworkManager[276]: <info> (mlan0): supplicant interface state: associating -> 4-way handshake abr 30 14:59:01 surface NetworkManager[276]: <warn> Connection disconnected (reason 15) PD: my machine is a Surface Pro and its wifi card has TONS of problems in linux, see https://bugs.archlinux.org/task/44269 and https://bugzilla.kernel.org/show_bug.cgi?id=69661 . However I believe that this problem is not related with those bugs
There is no 'reason 15' in my journalctl. However, for linux 3.19.3, there is 4-way handshake completed messages: May 02 14:42:58 Archenlighter NetworkManager[340]: <info> (wlo1): supplicant interface state: associating -> 4-way handshake May 02 14:42:58 Archenlighter NetworkManager[340]: <info> (wlo1): supplicant interface state: 4-way handshake -> completed May 02 14:58:51 Archenlighter NetworkManager[354]: <info> (wlo1): supplicant interface state: associating -> 4-way handshake May 02 14:58:51 Archenlighter NetworkManager[354]: <info> (wlo1): supplicant interface state: 4-way handshake -> completed May 02 18:20:12 Archenlighter NetworkManager[354]: <info> (wlo1): supplicant interface state: associated -> 4-way handshake May 02 18:20:13 Archenlighter NetworkManager[354]: <info> (wlo1): supplicant interface state: 4-way handshake -> completed But during the time linux 4.0.1 kernel was active there is no 4-way handshake message, however I found the following messages in journalctl during the time linux 4.0.1 kernel was in play: May 02 14:52:49 Archenlighter avahi-daemon[336]: Leaving mDNS multicast group on interface wlo1.IPv4 with address 192.168.137.100.

Solved for me! Apparently the problem in my system was arising due to some conflict because of the 'broadcom-wl' package being installed. It came to notice when the broadcom-wl package was upgraded and then the same problem arose as that due to upgrade to linux-4.0.1 kernel. I have now removed the 'broadcom-wl' package and upgraded the system to linux-4.0.1 kernel and my wifi is working again.
I've experienced the same problem After updating the wifi stop working Im using a dell mini10 03:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) I tried to remove 'broadcom-wl' package' but didnt work for me probably Im doing something wrong. Can you post the terminal screenshot?
You can check whether broadcon-wl is installed by: pacman -Q broadcom-wl if its installed, above command will show the installed version Do: sudo pacman -Rns broadcon-wl This will do a complete uninstall of broadcom-wl and its dependencies sudo pacman -S linux linux-firmware wpa_supplicant -> upgrade the linux, linux-firmware and wpa_supplicant Restart and check if wifi is working now
N.B. There are other related packages to broadcom-wl like brodcom-wl-dkms, you should remove any such packages if they exist
I'm running Ubuntu 15.04 on a Lenovo Carbon X1 3rd gen. After I updated to kernel 4.0.3 my wifi constantly drops, and iwlist wlan0 scan only shows the network I was last connected to, none of the other networks visible when wifi is working. Booting with default 3.19 seems to resolve the problem. 04:00.0 Network controller [0280]: Intel Corporation Wireless 7265 [8086:095b] (rev 59) Subsystem: Intel Corporation Dual Band Wireless-AC 7265 [8086:5210] Flags: bus master, fast devsel, latency 0, IRQ 46 Memory at f1000000 (64-bit, non-prefetchable) [size=8K] Capabilities: [c8] Power Management version 3 Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [40] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 34-02-86-ff-ff-1f-fb-5d Capabilities: [14c] Latency Tolerance Reporting Capabilities: [154] L1 PM Substates Kernel driver in use: iwlwifi

The issue must be elsewhere.
Whoever has issues with iwlwifi (Intel card), please open a separate bug and CC ilw@linux.intel.com. You can also send an email to that address (not through bugzilla).
