OMV5 on Raspberry 4. After I installed docker plugin, wireless network connection stopped working

I think it is due to a DNS issue after the docker is installed. If I uninstall docker, my connection to the internet is working again.
My wireless connection settings is in the wpa_supplicant.conf file.

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
ssid="mywirelessonnection_2.4"
psk="wirelesspassword"
}

Please help!

Hasmar04, I tried your suggestion. It didn't work.

I was able to get DNS resolution by adding the following to /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

The resolv.conf doesn't have any nameserver entries before.
Sorry, I am a newbie here, but can anyone explain why this is needed for docker but when I uninstalled docker, the nameserver entries isn't needed? I don't really like modifying files that I don't understand. Is there something else with my build that I should look at to resolve this issue?
