When I try to connect my TC60 camera to my TP-Link Archer C80 router, the TC60 LED flashes red swowly, router does not allocate an ip addreess, and camera says Format SD card. I'm not able to use the Panasonic SD Formatter as I have a UBuntu (i.e. NOT a Wondwos one) computer. So I used GParted on my computer, formatting it to Fat32. However, still same problem. So what file system should I use to format the SD card?
