Could not see any visible networks on UP core plus after installing Ubuntu 18.04
I have a UP core plus board. I followed** https://wiki.up-community.org/Ubuntu_18.04** to install Ubuntu 18.04 on the board. I also installed Ubuntu kernel 5.0.0 locally from debian packages.Then installed the Ampak firmware for WiFi and Bluetooth locally from debian package. So basically I set up my board as said in the wiki link.
Now I can see wlan0 interface when I execute iwconfig. But when I do iwlist wlan0 scan , there are no scan results.
There are no visible networks in the WiFi settings menu.
As per the link , the WiFi should be up and running if we follow all the steps mentioned in the link.But in my case I could not see any networks around me.
