Help, my wifi slider is grey. (Won't enable)

So last night my Huawei Ascend G630 turned itself off with 28% battery left. When i turned it back on the wifi symbol in the top right was just a shell, i thought 'ok, my wifi is disabled, better turn it on'. However, when i went to turn it on i discovered the slider was off and gray. Meaning i can't turn it on. When i open the wifi settings it just says 'wifi turning on' and doesn't get anywhere with that. I'm considering a factory reset but if anyone has a solution please let me know.

Thanks.
