Recovered file fragments on all firmware I have downloaded.
TRYING TO DOWNLOAD FIRMWARE TO BACK LEVEL A RELEASE. MY LAN USING RBR840, RBS840, AND RBR750 . ALL DOWNLOADS SHOW RECOVERED FILE FRAGMENTS, AND GET ERROR WHEN I UPLOAD MANUALLY. ANY IDEAS?
THANKS!

This is an awkward topic. It is unusual to have "two routers" (RBR840 and RBR750) in the same system with one satellite (RBS840). Is this correct, or is the 750 a satellite?
The most recent firmware version for the RBR840/RBS840 is v4.6.14.5

The most recent firmware for the RBR750RBS750 is v7.2.7.15
The Orbi AX products seem to have serious problems when the firmware on the router is not the same as the satellites.
If this is the case, then it appears that all of them should be running the latest firmware that they have in common, which is v4.6.14.3.
- BPaulAspirantI have a rbr840, rbs840, rbs84, rbr750 in net work. I didn't have any speed issues until I installed Kenitic fiber 1 G service. Now the router shows 900+ my up and down, but satellites all have only 80 mb up and down. I will try to change all.the firmware to match. My option is to get net routers, but probably will.not be net gear. My hang up is I really like the Armor software.
It would be really helpful to know how these four devices are connected. I assume that the RBR840 router WAN port is connected to the Kenitic fiber box. How are the two RBS840 satellites connected to the router? (over the default WiFi connection or 'wired'?). What is the RBR750 router connected to... and how?
As FURRYe38 mentioned ".chk" is indeed a Windows file extension that has a number of different uses. One common use is for recovered file fragments. Another common use is for the firmware image which is to be installed on electronic devices.
What Browser are you using? I use MS Edge to download FW files most of the time. Opera or Firefox can do as well.
Only need to unpack the downloaded .zip files once they are downloaded fully. Do NOT attempt to open the .chk files. Just use a web browser to send the .chk files to the RBS first, then RBR lastly.
