My internet resets itself when using any form voice channel

I live in Japan and use a pocket wifi for internet. I have discord set to automatically start up when I turn my computer on and I never have any issues with my internet or connectivity in any way. However i've continually had an issue of my wifi turning itself off and on without me touching it, which I recently realised only ever happens when im in a voice channel on discord.

I can sometimes go weeks without joining a voice channel on Discord, and during this time my internet will never reset even once, which is how I know that Discord voice channels are the cause. Other voice calling programs such as zoom don't seem to cause any problems either.

I'd like to know if theres a way to fix this because it can sometimes reset itself up to 5 times within about just half an hour!
