Could not see any visible networks on UP core plus after installing Ubuntu 18.04

Shm

Hello,

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.
Please help!!!!

have you connected 2 antennas to the on board WiFi module?

Thanks for the reply.
Is it necessary to connect 2 antennas to the board?
Is the wifi module embedded to the SoC right?

Is this the antenna to be connected to the UP core plus?

yes that is an external antenna which can be easily connected to a chassis.
The WiFi module in on the board (not inside the SoC.
You can see the module between the 2 white 100pin connector.
The WiFi module is dual band and you should connect 2 antennas for best use.
