Hi folks
I have been dual-booting one of my laptops with Windows 10 and OpenSuse Leap 15.1 for months without any real problems. I booted OpenSuse up the other day and found I had not got an Internet connection. (Last time I had used it, there had been no problem with the Internet, or connecting to other computers on my home network *)
I opened Yast > System > Network Settings to find that the adaptor was showing as ‘Not Connected’. ‘ip a’ in a terminal showed that Wlan0 was down. I could bring it up by typing ‘ifup Wlan0’, and then everything worked fine - which means that all the settings are OK. I use a fixed ip, but I tried using DHCP to see if it made any difference, but it was the same. Rebooting with the interface up resulted in ‘not connected’ and the interface down again when the system came back up.
I have done a complete new install of the whole system. Same result - ‘Not connected’. Can still manually bring the interface up.
So, the wireless adaptor is not connecting automatically.
System is as follows:
Acer Aspire E5-571-304M
Motherboard EX50-HB
Intel Corei3-4005U
12GB ram
Qualcomm QCA9565/AR9565 wireless adaptor
SSD: CT240BX500SSD1 (system)
HDD: WD10JPVX-22J (for data only)
Output of ‘lspci’ contains the line:

Output of ‘dmesg | less’ contains the line:

I can’t find any command which will bring the interface up automatically. Can anyone help?
Many thanks in advance!*
