Public bug reported:

Hi,

I had ubuntu 16 and my home wifi never had issues. Now i installed lubuntu 
bionic now i can never connect to my home wifi.
I am getting below message on running command - 
nmcli dev wifi connect myssid password mypassword

Error: Connection activation failed: (5) IP configuration could not be
reserved (no available address, timeout, etc.)

I can not use my system any more and any help will be appreciated to
resolve the issue. I posted this issues in askubuntu and no response so
far.

Please help. Please let me know any more information needed.

        wifi (rtl8188ee), 40:B8:9A:09:D7:9E, hw, mtu 1500


Note - I can connect to hotspot network on my phone with no issues.

Thanks
