Thanks for the ip a and especially the ip r!
Hmmmm... this is a 'tough one', but probably will turn out to be some 'basic glitch'
(like: [randomly...] no encryption, US, ?wpa_supplicant?, duplicate-of-enp3s0 subnet, ...)
Can you find the 192.168.x.y address this wifi has on another OS/device? (..0.y might be 'BAD' dup/sameSubnet! Is enp3s0 CABLE plugged into SAME routerBox which provides wifi???)
**>>>>** Have/can you try rebooting withOUT wired-ethernet connected? ?? **<<<<**
'In desperation' (&since I think [2nd] half of #13 is missing) maybe repost #13 and/or rerun:
./wireless-info (better yet, rerun&post after rebooting withOUT wired-ethernet connected!)
(-after- you generate that #9 "wireless-info.txt",
by: ./wireless-info [OR even, without chmod: sh wireless-info]
THEN you can plug in cable & post it, OR even reboot [w/cable] and that .txt file will still be there [with info from being run withOUT enp3s0 cable] ! )
...I hope you can figure out what I'm trying to write here...if not, ardvark can explain MUCH better
yes, I think the 'key' info is:
[ 169.038649] wlp2s0: deauthenticating from 40:4a:03:df:42:c3 by local choice (Reason: 3=DEAUTH_LEAVING)
BUT I don't know this 'stuff' well enough to solve it, sorry.
Here's a 'clue' for ardvark/other LQ'ers (from web-search of: DEAUTH_LEAVING)

p.s. Did you get skype working? OR do you still need help on skype?
