RBR750 unable to assign IP addresses after reboot
Hi, every time I reboot or unplug my router to move it, all my devices will disconnect and will have an "unable to assign IP addresses" error. I have 48 devices and all of them will not connect. I wo...
Update: One of the satellites says updated but the firmware number did not change? It is still on the previous version. Satellite #3 also wont connect now.
Edit, I don't understand what's going on. Satellite 3 wont reconnect now
- Satellite 1 and 2 reappears and disappear. I downgraded 1 and 2 but 1 still shows the 4.6.8.2 FW
- Attached devices only shows #2 connected.
- Firmware pages only shows #1 connected.
i have tried rebooting and factory resetting.
Did you do the firmware updates via ethernet or WiFi? Sounds as if you've gotten several pieces of your setup out of sync as far as the firmware version goes. Be very methodical and retry installing the firmware via ethernet. Download fresh firmware files from Netgear.
Manually reinstall the firmware on the sats first then the router last. Do a factory reset of the sats and allow them to stabilize and reconnect to the router. If they won't connect then power them off while you reinstall the firmware on the router. Factory reset the router. Power off your modem and router for at least 1 minute (5 minutes might be better). Power up your modem and allow it to stabilize . Then power up your router and allow it to stabilize. Check the firmware version the router is reporting. If it is what you installed, power up the sats one at a time. Allow each sat to connect and report good backhaul before powering up the next one in your chain. (This can take pretty long time–easily several minutes.) When all sats are back up and reporting good backhaul status. Begin a reconfiguration of your system. (If you have a backup config file use it.)
If the sats won't connect or are showing odd information on the attached devices page of the router web-based UI, tell the router to "forget" the sats and start over by adding them back in. Again, one at a time.
I know you've told us you tried all this before but please attempt it one more time. Be methodical and patient between steps. It will take more time to let the router and sats stabilize between steps then it does to perform the step. Good Luck!
I was able to update it thru ethernet, but I am still getting the blinking white light and IP address errors.
I don't want to constantly factory reset when I need to reboot to save changes.
My router is in the attic crawl space and it is difficult to reach.
When I plug my laptop into the router, I get internet, but not through wifi.
Wifi on the phones will keep trying to reconnect, on the PC it will say connected but no internet. When I try the troubleshoot, I get the error below.
Since you got the system updated, are the router and sats showing the same version? Is the router flashing white or the sats or both? Can you please list all the settings on the router "Internet" and "Wireless" web pages?
You mentioned the router is in an attic crawl space, is this space climate controlled, i.e., air conditioned? If not, try bringing the router into a cooled space. The Orbi system is designed to run best at room temps.
Yes, all the versions match now.
The router was blinking white after a reboot or if I unplug it. Everything works fine after a factory reset.
I'll try moving the router back down.
I just want to thank everyone trying to help me solve this issue.
Settings attached.
Sounds like your system has recovered. If you have still have issues try deselecting "Enable AX" from 2.4gHz band. Some have found this helps stabilize satellite communications. Glad we could help.
- It happened again after I rebooted changing "enable ax" option. Is there a way to force the IPs to reset?

It sounds like you are seeing a problem where the DHCP server on the router stops issuing addresses.
In my experience the problem shows up when you get a larger number of devices probably more than 40 or 50. I have around 80 now.
I don't know if your problem is actually the same as what I'm seeing but what I have done recently is below.
If you use a different server as the network DHCP server (for example a NAS that's always switched on) the problem disappears completely.
Recently I've changed the DHCP range on the Orbi to 2-249 because the Orbi satellites transition through having an IP address ending in 250 which means there's always a possibility of an IP address clash and that is bad for the network.
Then when I reboot and see the number of devices increase but then start falling and verify some of my devices can't get an IP address I change the range to 2-248 and apply, then if things are still broken I change it back to 2-249 and apply and continue until all my devices are getting IP addresses ok again.
- Your issue sounds very similar to mine. The only things I have running 24/7 are the smart switches.
Where do you go to change the settings you mentioned?

The Field to look for is "Ending IP Address".
It should be obvious this restricts the range of addresses the DHCP server considers
it owns that it can use for clients.
Is it possible to have the routers on 192.168.1.xxx but my devices on 192.168.2.xxx?

Previous Orbi routers placed devices on the primary network and devices on the guest WiFi network in the same IP subnet. I believe that the newer AX products place devices on the primary network in IP subnet and devices on the guest network in a separate IP subnet. The typical subnets used are 192.168.1.x for the primary network and 192.168.2.x for the guest network.
(Someone please correct this if my impression is incorrect.)
It seems like all my devices and routers are on 192.168.1.xxx
every time I reboot, a conflict happens between the routers and devices.
I think I see the routers are trying to set 192.168.1.250. everytime I reboot all my devices say there is an IP conflict and I can't connect to the wifi.

The Orbi satellites appear to always start out with a .250 address and if the DHCP server decides to stop allocating addresses they stay at that address. Stupid really as .250 is within the default DHCP allocation range so a conflict is possible.
I set my DHCP range to 2-249 to avoid this possible problem.
No.
Try setting the Default IP address pool range to 192.168.1.100 thru .200. Then this will give you a pool size for IP address reservations ON the router and IP address ranges on either side of the pool for static assigned IP addresses that are set ON devices.
What FW version are you using?

Thank you, where do I change the DHCP range? Under Lan setup?
my FW is, 4.6.5.14
if I end the range at 200, can I still reserve IPs at 201 - 249?
No, the .201 thru 254 range is available for static IP addressed devices.
You might consider updating FW as well:
Sorry, when you mean static IP devices, you mean the devices I have listed under Address reservation?
Like i can set my printer to 201 in Address reservation? or do I need to change the printer IP address within the printer?
Thanks
IP address RESERVATIONS are set ON the router with in the IP address pool range. STATIC IP addresses are addresses that are set ON devices. These are out side of the IP address pool range. These are two different items.
For an IP address RESERVATION on the printer, would be inside the IP address pool range. You can set a static IP address ON the printer that's outside of the IP address pool range. I do this for my 3 printers, as they don't need any router management and the IP address for these printers never changes.
I see, thank you for clearing that up for me. I'll look into this.
I've had lots of problems with the DHCP server.
It has been worst on the AX routers (my 850 series) but I have also seen it (occasionally) on the 50 series.
The symptom is the DHCP server simply stops issuing IP addresses.
Excluding address .250 from the DHCP address range has improved the situation a "lot" but I'm not sure if this is the only problem with the DHCP server.
At least my Orbi is usable now, 😉
