Do you have to disable cellular data when using a router off-grid that's not connected to the internet?
I recently took some WLED projects to a gathering and I prepared in advance with a non-internet connected router to control them. At home I had the router live, controllers connected and everything seemed normal.
When I got out to the site where there was no cell service or internet, the controllers weren't showing up in WLED, despite being connected to the router just as before. I ended up connecting to a neighbors router who had starlink, and I was able to get everything online and all set that way.
A friend told me that I might need to disable cellular data in those scenarios. Is that true? Is this a known issue?
