RBR750 primary wireless not working
I have an RBR750 with 2 satellites (one wired backhaul, one wireless backhaul) and every month or so I need to do a complete reset of my router system. I notice that the primary network wireless will...
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.

What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Firmware
V4.6.5.14_2.0.54Modem is SB8200, ISP is comcast. I don't think there's an issue with the ISP or modem, the guest internet always works and wired to modem always works.
Distance between routers and satellites are over 30 feet. Total square footage of 2600. 1 router and 1 satellite on 1st floor, 2nd satellite on 2nd floor.
5ghz only has 48 channel available, no auto available. 2.4ghz is on auto. Not sure if it's a channel issue.
Can see about 5-8 neighbor wifi networks.
My suspicion is that the router itself craps out or maybe some memory or DHCP assigning issue that makes it unusable on the primary network after a month or so of continuous use. I'll have to reset the router back to original settings and then reset it up again with the old SSID.
Any suggestions?
So, this system works fine for several weeks. Devices connect to both primary and guest WiFi networks. Any devices 'wired' to the router or satellites?
Then... how does it 'go bad'?
- All at once? Every device on the primary network suddenly has no correct IP address and has no internet?
- Gradually, one device after another loses connection?
You are correct that those "169" IP addresses reflect that devices have attempted to get an IP address using DHCP but were unable to do so. These are called "Link Local" addresses: https://en.wikipedia.org/wiki/Link-local_address
Does the Orbi log file include entries where IP addresses have been assigned using DHCP?
All devices on the primary network are unable to connect at the same time or close to the same time. I can't tell if it's sequential within seconds of each other or all at once - all iphones, ipads, laptops, wifi devices are unable to connect main wifi. RBR750-->wifi backhaul-->RBS750-->wired-->laptop will also not work.
I just reset the router a few days ago, so the log only shows recent successful DHCP assignments. The next time it dies, I can try to see if I can access the log, but I'm assuming it will have to be a wired connection since I can't do it from the guest network.
