Running Kali linux 2020.2, when I try to connect to a public WiFi network (PEAP MSCHAPV2), it disconnects, almost like clockwork after 10 minutes. The reason this worries me is:
- I lose internet connection after the exact lease time of 600 seconds is passed.
- NetworkManager however reports I should have full connectivity, but pinging 8.8.8.8 returns nothing. The connection is indeed strong, along the lines of: Link Quality=90/100 Signal level=55/100 Noise level=0/100
- A windows testbox is sitting right next to it and even with it's lousy internal wifi, it maintains a stable connection
Here are some log files:

How I interpret this: I get a lease of 600 seconds, according to protocol, the lease is renewed after half the time. Then at 14:46 the lease is expired, I should get a new one, but that's the exact point I lose internet connection.
However NetworkManager says:
Code:
sudo nmcli g status
STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN
connected full enabled enabled enabled enabled
And iwconfig:
Code:
Link Quality=100/100 Signal level=59/100 Noise level=0/100
I thought this would be due to MAC Address randomization, so in "/etc/NetworkManager/conf.d/" I added a file "no-mac-addr-random.conf", containing:
Code:
[connection]
wifi.cloned-mac-address=preserve
wifi.mac-address-randomization=no
[device]
wifi.scan-rand-mac-address=no
For completeness, the connection-definition itself contains:
Code:
[connection]

Simply just "nmcli c down PublicWiFi" and "nmcli c up PublicWifi" restores everything back to normal... for exactly 10 minutes and then internet drops again, but networkmanager just claims this connection has full connectivity. I'm sure I have to do something wrong or there is some mechanism I'm unaware of... this is driving me insane.
Could anybody help me?
