RBS850 - Out of Sync
Hello, My Mesh System satellite (RBS850) is showing Out of Sync. I have tried to connect directly to it, via ethernet cable, and: - can not connect to it via http://192.168.1.250 - it correct...
CrimpOn thank you for your message.
I confirmed that the satellite uses 192.168.1.250.
I have other same model satellite and indeed it uses 192.168.10.250.
It seems that the http service for some reason is not starting on 192.168.1.250 and this is the whole problem.
If Netgear is not willing to help then this product is useless. I wish there were other way to flash the firmware...
My understanding is that Netgear's primary response when a device does not work is to replace it. But that only applies if it (a) is part of an original purchase from an authorized retailer (not used), and (b) is within the warranty period.
I find the default LAN IP issue frustrating. After a Factory Reset, if the satellite is responding to 192.168.1.250 that would seem to indicate that it has firmware from before Netgear made that change to 192.168.10.250
Was this satellite "working" before and has stopped working, or was this recently acquired and has not been made to function yet? (i.e. could it actually have older firmware on it?)
Knowing the MAC address and the LAN IP address are key because most Netgear products go through a process when powered on that involves activating a TFTP server to accept a firmware load. I have done this on a couple of Orbi satellites (but not recently) and found it to be "not fun". I would get the firmware file loaded on a PC. Have the TFTP client ready to go. Then power up the satellite. Try to start the transfer too soon... fail! Wait a second too late.... fail! I failed five times in a row and was about to dump the device in the trash, and thought, "what else do I have to do right now?" Worked!
Since TFTP operates over UDP rather than TCP, the device sending packets gets no response from the server after each packet. That's also why it matters so much to have the correct LAN IP address. If it is really 10.250 then it will not accept a TFTP transfer to 1.250 (or the opposite).
CrimpOn Hmm I haven't thought about TFTP... will scan and see if this port (UDP) is open and will let you know. I bought this satellite second hand on marketplace and the seller has just admitted that it had downgraded the firmware to V4.6.14.3_2.3.12 on all of his mesh devices (many)?? Perhaps this is the issue?
FURRYe38 I don't know what version of the firmware is there as on the Orbi routers admin interface it shows only Model Name - RBS850, IP address and that it is out of sync. The Device Name and Current Firmware Version are blank.
CrimpOn - TFTP is not running on this satellite. Just checked and no connection - no UDP port is open.

Just curious. How would a person determine that a UDP port is open or not? UDP is a "connectionless" protocol. The typical method is to perform some operation which usually results in a response. Send a query to a DNS server, for example, and we expect to get a response back. As I stated, my personal experience with using TFTP on a satellite was frustrating because the TFTP process functions for a very short time during the boot process.
Orbi routers actually have a terminal interface which can be used to connect a computer directly to the motherboard of the unit. A guide to connecting to an RBR750 can be found here:
This is WAY "over my head". I have connected to an RBR750 and observed the boot process. Have looked at the files, etc. Have NO IDEA how a person could use this interface to load firmware on the device.
So if you factory reset the RBS and wait 5 minutes and with a wired PC connected to the back of the RBS, set a static IP address of 192.168.1.49 on the PC usuing 255.255.255.0 subnet mask, Can you access the RBS web page at 192.168.1.250 at all?
If you can get in here, you could update the RBS to v7 FW if you have that on your current RBR.
Ya, v4 FW I believe was prior to NG changing to what is seen out on v7 FW. I know there was a point that we lost RBS self service web page access as historical process to gain access stopped working back then. Not sure if v4 was effected or not.
If you can't get the RBS to update at all, might ask if you can return the RBS to the seller.
