Lenovo Edge E325 with AMD APU Wifi Hard Block after suspend

My wifi on my notebook is not working after suspend. According to rfkill it is hard blocked:

rfkill list
0: tpacpi_bluetooth_sw: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
2: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

I'm unable to activate wifi again, I need to restart in order to get it working again. I'm also using tlp. But even when I deactivate the tlp services and uninstall everything, it is still not working.

My wifi kernel modules are:

lsmod | grep wifi
rtlwifi                65536  3 rtl_pci,rtl8192c_common,rtl8192ce
mac80211              647168  3 rtl_pci,rtlwifi,rtl8192ce
cfg80211              466944  2 mac80211,rtlwifi

My kernel version is:

uname -a
Linux Somnium-Mobil 4.3.3-2-ARCH #1 SMP PREEMPT Wed Dec 23 20:09:18 CET 2015 x86_64 GNU/Linux

Re: Lenovo Edge E325 with AMD APU Wifi Hard Block after suspend

I have the same issue with my laptop, Lenovo X121e with AMD E-300 APU and RTL8188CE WiFi adapter, which happens only on Arch.

The only thing that helped is loading BIOS defaults. Not sure if it's a permanent solution.

Nothing else I found here helped. So try that for now. I also have updated kernel, but problem persisted through updates, so it probably doesn't matter.

Other possible solutions (did not help me, some maybe unrelated but I tried):

• Blacklisting wmi module (seems to be a common fix).

• Hardware WiFi switch (not present on my laptop)

• Blacklisting modules, blacklisted in Ubuntu, since this issue wasn't occurring there

• Unloading WiFi driver before suspending, then reloading it.

• Unblocking using rfkill with WiFi driver unloaded.

• Changing TLP configuration, or removing it.

• Configuring network with different tools (NetworkManager / systemd-networkd / netctl).

• Changing WiFi driver parameters (related to power saving).
