I upgraded using 'oupgrade -l' on 30/09/2018 and unable to connect WiFi following above steps by an.arshadali. Below is the result: root@Omega-4D3D:~# cat /etc/config/wireless config wifi-device 'radio0' option type 'ralink' option variant 'mt7628' option country 'US' option hwmode '11g' option htmode 'HT40' option channel 'auto' option disabled '0' option device_mode 'apsta' option op_mode 'preference' config wifi-iface 'ap' option device 'radio0' option mode 'ap' option network 'wlan' option ifname 'ra0' option encryption 'psk2' option key '12345678' option disabled '0' option ssid 'Omega-****' config wifi-iface 'sta' option device 'radio0' option mode 'sta' option ifname 'apcli0' option encryption 'psk2' option network 'wwan' option disabled '0' option key 'MyPassword' option ssid 'MySSID' config wifi-config option key 'MyPassword' option ssid 'MySSID' option encryption 'psk2'

I ended up bricking my device.The hard reset on my expansion dock resulted so.I installed PutTy. Serial Communication didn't work so I had to open terminal and flash firmware.

MAYBE the cable was 2 separate USB connectors, 1 for webcam, 1 for microphone? Like a Y connector with shared power / gnd? no idea lol

There is a burst of energy required when the WiFi transceiver begins operation. You, as many of us, discovered the magic moment that it happens. Not knowing your circuit I can only speculate. As such, you may get past the burst point with a "large" amount of capacitance across the power input and ground. Using an expansion dock (which you are not) I'm using a 470uF cap just downstream of a 5V regulator just at the +5/gnd dock inputs (there's actually a small cap just upstream of the regulator as well). This has apparently "solved" my problem, however occasional brownouts occur putting the system in the dreaded 3 byte/4 byte reboot issue (another big topic on the forum). Try a cap and see if it helps. Additionally reduce inductance (wire length) between the power supply and O2. If those don't help, you'll need a new power supply. --Bill
