Wifi is not connecting

My octopi (Rasp 3 model B) will not connect to my wifi

I followed the "Getting your WiFi Connection working* FAQ all the way down to the "Other Diagnostic Commands" and i scanned to see if my Pi can see my network and it can, but when i run the "Ifconfig wlan0" im getting nothing. Instead im getting flags=4099

please someone help

Check the LEDs which are and are not lit on the corner of your Raspberry. It's possible that this is related to the link speed.

I’m only getting the red LED. Green led will show on boot and then go away after the first 10 seconds
