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...

I will try a factory reset of that RBS, then do a reconfiguration from scratch for just that sat.
Factory Reset of a satellite is not nearly as involved as resetting the router. Chances are, when the satellite reboots, it will connect automatically to the router. Total time: under five minutes. There is nothing about a satellite to "configure" except for perhaps a custom name that has been assigned to the satellite in the Attached Devices display (which is for human interest only).
Lo and behold, after doing nothing to my offending RBS, it stopped broadcasting the GN. No idea why it decided to do that. Of course, I have no idea why it started to radiate that signal in the first place. I did notice in the sat's web-GUI page the 2.4 GHz column "Wireless Mode" reports a speed of "Up to 240 Mbps". Previously, I believe that number was listed as "Up to 500 Mbps". I do have AX disabled for the 2.4 GHz band.
Still curious why furrye38 recommended enabling ALG SIP and reseting the DHCP range to .100-.200 for this latest firmware update. My system appears stable with 4 days of uptime. While I cannot prove it with data, it appears my web pages load a bit slower than before but that could be due to Black Friday server overloads!
NIce. Mysterious Orbi systems aren't they? LOL
Another poster mentioned they enabled SIP ALG on there system and seemed to work better. Normally on Orbi systems SIP is disabled. On Nighthawk routers it's enabled by default. Theres been information that SIP should be disabled for voice or video communications over the years however I've not seen any problems with having it enabled whatsoever. I think it may have been a troubleshooting step at some point for people seeing issues with Voice communication problems over the years. I Think there could have been other underlying factors as well besides having SIP enabled.
I've been using the smaller sized default DHCP IP address pool size for many years now. Got this from a competing router mfr that defaults there stuff to small sized pool instead of wide open. Most homes will never have 250 devices connected and having a small size pool for the router to work with, the router doesn't have to work at hard to deal with devices and IP address assignments. I've carried this over to my use of NG routers and has worked well for me and keeping NG stuff stable. Its always adjustable of course.
Be sure to save off a new backup config to file for safe keeping.
Remember you can disable Auto FW Updates now.
Yep. Never can tell what those spurious electrons will do! đ
I will try enabling SIP ALG and see if there is any change. I already limit my DHCP pool to only 50 devices. I use XXX.XXX.X.1 thru .50. Never had an issue with DHCP assignments on either my original ORBI 50 or the current ORBI 750 using that scheme.
I also use IP reservations for every one of my 42 devices. It is my OCD showing through but I find it way easier to troubleshoot device connection issues if I do this. It also allows me to immediately notice if a "new" device has connected to my WiFi. (BTW, I do not use static IP addresses on the device side. It is very difficult/not possible on some devices to set this up.) While I cannot prove it, I believe folks having issues with DHCP assignments are overdriving their systems with too many devices. With 42 devices, I'm probably bumping up against the limit sometimes. When my current 750 gives up, I'll upgrade to the larger capacity 800 or 900 series.
Sounds like your system IS now working well and your not seeing any IP address assignment issues. Be sure to save off a new back up configuration to file for safe keeping. Saves time if a reset is needed.
https://kb.netgear.com/000062080/How-do-I-back-up-the-configuration-settings-on-my-Orbi-WiFi-SystemYa seeing problems in other NG router models and sometimes here on Orbi, wondering if there is a problem with using the wider IP address pool size. Been thinking there maybe some underlying issues with this kind of default configuration. Since I've been using the smaller pool size for years, I've not seen these issues to date or any oddities in this area. I may bring this up with NG and see what could be done. We know there are some other underlying issues at hand that need to be fixed. These could be causing extra problems as well.
I use this as a kind of a general rule for STATIC assigned devices, items that don't need much or any router management, devices that need some access but can be set and left alone and not accessed but occasionally, and devices that do have management pages that support input of static IP addresses. Devices like Printers, NAS, Cameras are some devices that don't need much and generally can be configured for Static IPs. I have 3 printers, 2 NAS and 3 cameras, all set for statics. Anytime I change out the home network router, I just make sure the incoming router has same network configuration and onces it's online, the static devices are automatically connected at there known IPs. No need for worry about them.
