Enable wifi under GUI

Hi,

I am using Machine model: Raspberry Pi 2 Model B Rev 1.1.

I am having issues connecting to the router using my wifi dongle. It was working flawlessly until I upgraded my ASUS TR-n18U router firmware last week. Since then my wireless dongle has not been connecting to my router.

As mentioned at the start of the thread. using connect wifi_somethingsomething_managed_psk, I get an error message “Connect command not found”

I ran the sudo apt-get update && sudo apt-get dist-upgrade to ensure that I am using the latest distribution.

When I run dmesg , it seems to recognize the dongle
