LIFX Mini White Bulbs not connecting

So i ordered the newest LIFX white mini bulbs and was able to connect them all to the Wifi network upstairs. I got them because my light switch is outside of my bedroom, I’m sick of having to get dressed to turn the light off before and after going to bed.

The Wifi is upstairs so do you guys think that the connection could be too weak?. I updated the bulbs and everything in one night, then when I went out somewhere and came back after 3 hours, I couldnt turn the lights back on.

Do you guys think a Wifi Extender would help fix this problem?. Anyways, below is a screenshot of my LIFX app showing the bulbs, though unresponsive or something, I can’t do anything. Thanks in advance for any tips.
