Hello,
We use rut 955 router, and gps has stop working on some of them (3 for now) after upgrade.
Reset, reflash bootloader, upgrade without keeping params has no effect.
Maps keep empty, and no coordinates are shown.
PS : Here's log i can see in system logs (i can see that only when there's a gps signal (antenna is outside), as soon as antenna is inside, no more warning logs)
