n300 model c3000 no wireless connection but workes using cable

Hi!

after a storm hit i unplugged my n300 (c3000) router just to be safe. then when turning on again it stopped providing internet connection wirelessly but it works perfictly fine when connecting it using the eathernet cable. not sure if this becuase of the storm since it works using the cable. all lights are turned on exept for the first and last one.

Do i need to buy a new one or is there another solution.

thank you
