Hello. I picked up an additional Orbi satellite second hand, an RBS750 to go with my RBR750 and an existing satellite. Needed to extend coverage in the house. The satellite is stuck on firmware V...

Thanks for chiming in everyone! Yeah, it does seem to be working, I just wanted to make sure that it’s an official firmware signed by Netgear, and it’s not something custom that a bad actor flashed onto the Orbi Satellite that could allow it to send network traffic / data elsewhere? Is there anyway for me to be sure about this? I connected to the Satellite via the Orbi UI on the web and couldn’t find anything in the settings to check whether or not the current firmware is signed by Netgear and is untouched.
Do you thinkStephenB that the ISP would be able to update the firmware if it was built custom for them?
AlsoCrimpOn, I’m considering downloading the firmware versions from the website that you linked to, to see if I can update it to the same (or newer) firmware from what you linked to be sure that it’s signed by Netgear. Not sure if I’m being paranoid.
AndMahoneyR, did you ever try to get Singtel to ever update the firmware? Did the V4.6.14.93 firmware get auto-updated and after that you couldn’t ever update?

Firmware would have been built by Netgear, but distributed by the ISP. The GPL says
RBK752-1STSQ For Firmware Version 4.6.5.93 RBK752-1STSQS / RBR750-1STSQS / RBS750-1STSQS For Firmware Version 4.6.14.92, 4.6.14.93So maybe to 4.6.5.93 (which also appears to be custom firmware).
nrmpflash might let you install main-branch firmware (Assuming the 1STSQ hardware is the same as other RBK750s, which seems likely).
