Aye, I’ve given my old NAS enclosure to a family member and they’ve never been so happy having the arrrr stack running on it and I think it’s like magic to them still.
However one step at a time and I’ll get them off Google Photos (I’ve plonked Immich and Jellyfin on their bedroom n100 box) and Drive if it kills me. Screw this bullshit of paying to store our data only for them to double down and invade their privacy.
If you can get someone else’s SIM card to see if it’s a carrier issue, and I know factory resetting sucks but it is the easiest way to discount a hardware issue :/
Good luck!
