Can I use a wifi extender to increase the range of my gamer room devices?

Basically have been troubleshooting the issue of my chroma devices on my PC flickering and dimming off and on for the last week or so. I think I isolated the issue to it happening whenever my Aether bulbs and light bar are connected to synapse (even when synapse overide is not on) can I use a wifi extender to see if that fixes the issue, it might be because I’m not even on the same floor as my router. However it also worked fine for the previous months and the issue recently happened a few weeks back.
