RBS20 bricked? red power led flashing

had an old pair of RBS20 satellites with red power led flashing

won´t connect to router

removed them

bricked?

searched a lot

what worked for me

1. removed satellites from router
2. updated router to last firmware version
3. download and unpacked satellite firmware version (same version as router)
4. connected the satellite by ethernet cable to router (RBR20)
5. changed router address (it was 192.168.1.1), changed to 192.168.1.200
6. used software TFTPD32, connecting to the interface where router was connected
7. uploaded the firmware to 192.168.1.1 (this goes to satellite, through router!)
8. that is all... repeat with other satellites
9. then add the satellite back to router using web interface!
