ubuntu 16.04 linux kernel 4.15.0-24-generic wireless

[Thammu]

I am not able to connect to wifi after update. Wireless connection is misssing in network setting. My ubuntu version is 16.04. And the kernel version is linux kernel 4.15.0-24-generic. I can connect to wifi when I go back to my earlier kernel version of 4.13,0-45 generic

As I am unable to connect to the net, obviously the command apport-collect failed. The kernel response is given below:

cgmei@cgmei-Inspiron-5370:~$ apport-collect 1782470
ERROR: connecting to Launchpad failed: Unable to find the server at launchpad.net
You can reset the credentials by removing the file "/home/cgmei/.cache/apport/launchpad.credentials"

My network device as in lspci is below:

Network controller: Qualcomm Atheros Device 0042 (rev 31)
 Subsystem: Dell Device 1810
 Flags: fast devsel, IRQ 255
 Memory at df000000 (64-bit, non-prefetchable) [disabled] [size=2M]
 Capabilities: <access denied>

Boot into the kernel with working internet, in terminal do

sudo apt-get install --reinstall linux-modules-extra-4.15.0-24

Reboot and see if wireless works

Yup! reinstalling worked. But it crashed on some other error. I sent the report. Do I need to send the apport report?
