i am new to linux ,i installed kubuntu 21.04 on hp elitebook 8470p with
Intel Centrino Advanced N 6205 Wifi Card
but when i connect to my wifi , i cannot access the internet , and my wifi works well with another devices such as my android phone.
So I tested the connection if it was connected correctly, and go to https://192.168.1.1
but i cannot connect to the router settings. i tried to restart NetworkManager Service,
reconnect to the wifi ... etc. But it's totally random, sometimes works , and sometimes no ... Is there any solution ?
