Description Michelle Bowe 2021-02-26 18:58:14 UTC 
SUMMARY

Connection which can reach the internet is reported as limited

STEPS TO REPRODUCE
1. Connect to a wireless network
2. See notification of limited connectivity and corresponding applet icon
3. check that you can reach the internet

OBSERVED RESULT

I can reach the internet, so notification is in error

EXPECTED RESULT

Either:
1. I can't reach the internet, so the notification was not in error
 or 
2. Upon sending/receiving network traffic beyond the LAN, the icon changes to indicate full functionality of connection.

False limited connectivity notification

2. Connect to WiFi network
3. Unplug WiFi receiver

Comment 5 Olivier BELLEUX 2023-06-15 12:24:29 UTC 
Same on opensuse 15.5:
– on wifi : applet with orange exclamation mark (!)
– on ethernet : applet with orange triangle

Notification :
"connectivité limité Ce périphérique semble être connecté à un réseau mais ne peut accéder Internet."
 "limited connectivity This device appears to be connected to a network but cannot access the Internet."

I can reach the internet normally so it is an erroneous indication.
