pci-Wifi unable to find networks after update

[elidd1]

I recently did an update and upgrade on my rolling kali.. I run this on a dual boot machine, and want to start by saying that when i boot to windows the same wireless card works fine and it used to work fine on the kali boot until the update/upgrade. Since the update the wireless card appears to be up and running but it doesn't see any networks and won't connect to the saved network. My usb Wireless cards all see the networks fine

i have run the following with the following results..

root@atreyu:~# dmesg | tail

I have also noticed that something (not sure if its related) is going wrong doing start up, where it says the following during startup

Warning:Failed to connect to lvmetad. Falling back to device scanning.

attaching a picture of boot screen as it happens so fast :

If anyone can help me trouble shoot this, i would be so grateful. I am currently very frustrated.

Ok so i had changed my default grub after trying to solve a different iissue..

commenting out my change, and adding back the original value in /etc/default/grub fixed my wireless card

 #GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"
 GRUB_CMDLINE_LINUX_DEFAULT="quiet"

I had made this change because suddenly out of no where , every time i shutdown my box it would automatically reboot. I had read in another forum to make the change i had above but that caused the issue.
