NM-applet showing exclamation point (!) but no identifyable issue

symptoms:
NM-applet showing exclamation point (!) a short time after starting PLASMA without having connectivity problems (wifi).
Although i'm experiencing one issue with a webcut widget: as long as the exclamation mark didn't show up i can click on the webcut widget and the page is opened in my webbrowser.
After the exclamation point appeared the URI is not forwarded anymore: socket operation timed out

what i did:
Journalctl doesn't show errors related to NM or nm-applet but it displays:

kde-open5[2100]: kf5.kio.widgets: KRun(0x564003344a50) ERROR (stat): 1   ""

and

maybe KIO/ Krun is the culprit??

# systemctl start NetworkManager.service

does solve it only for a short while, also disconnect and reconnect to the wlan network.

I need some help in finding a cure for what's going on. Is there another way to debug what the exclamation point stands for?

my System:
Host:          Kernel: 4.9.37-1-lts x86_64 (64 bit gcc: 7.1.1) Desktop: KDE Plasma 5.10.4 (Qt 5.9.1)

                  IF: enp5s0 state: down mac: <filter>


EDIT: thats journalctl looks like after successfully run the operation (just for the first minutes after boot)

Re: NM-applet showing exclamation point (!) but no identifyable issue

You on a  wrong tangent, something is wrong with your connection, this has nothing to do with KDE at that point. Post a

dmesg
systemctl status NetworkManager

V1del thanks for answering

since complete dmesg output is quite long you'll find it here: https://pastebin.com/0XJSv5uW

EDIT: What i did just now: disabled 802.11n and enabled software encryption according to https://wiki.archlinux.org/index.php/Wi … on#iwlwifi.
Seems to result in a much better connectivity also the warning sign in nm-applet didn't reappear til now and clicking the webcut widget the URI is forwarded successfully   -- for the time being;)
dmesg output at least without "Microcode SW error".
But shortly after that the exclamation point returned roll, but connection is (still) good but URI links are still not forwarded!

dmesg says (in extracts):

iwlwifi 0000:02:00.0:No association and the time event is over already...
wlp2s0: Connection to AP 5c:49:79:00:d8:86 lost
wlp2s0: aborting authentication with 5c:49:79:00:d8:86 by local choice (Reason: 3=DEAUTH_LEAVING)

According to https://www.utdallas.edu/~neerajm/publi … ttacks.pdf the deauthentication/disassociation may have something to do with a Denial of Service= DoS attack
So my routers log tells me (frequently):

DoS (Denial of Service) attack SYN Flood got discovered

A connection to the internet via another router does not produce the error.

I reseted my router and reconfigured it basically and -what i forgot to mention before: when i amplify the signal with a (fritz)repeater as i have to due to weak signal/ long distance the exclamation point returned.
Any advice? What did i miss? hardware, maybe the repeater? yikes
