Decided to install Kubuntu on my old laptop HP 15-ac002ur. Everything works fine except WiFi (in Windows it was OK). I've seen very very many similar issues about hard block but none helped. Details follows.
WiFi network device is recognized:
$ lspci | grep Wireless 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)
WiFi network adapter is created:
$ ip a ... 3: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether d8:5d:e2:4d:ec:ee brd ff:ff:ff:ff:ff:ff
But it could not be enabled:
$ sudo ip link set wlp2s0 up RTNETLINK answers: Operation not possible due to RF-kill
rfkill shows hard block:
$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes
To unblock I've tried:
rfkill unblock all
- Pressing airplane mode switch Fn+F12 or just F12 (looks like it does not work at all cause soft block value does not change too)
- Switching to https://github.com/FreedomBen/rtl8188ce-linux-driver driver
- Reset BIOS settings
- Power reset laptop by manual from https://support.hp.com/emea_africa-en/document/c01684768
Interesting thing - few times I've seen that WiFi enables for few seconds and I've even seen surrounding WiFi networks in network manager list but then it disables.
Happily my main laptop is ThinkPad and I face no troubles there but I'm still interested in making this HP work and will be very glad if someone could help.
Thanks in advance.
