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 not work (devices unable to connect, not getting assigned IP addresses and it would show 169.xxx.xxx rather than 192.168.1.x). The guest network will work just fine if I connect to it. It's already on the latest firmware. Is there any solution to this? Thanks!

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. https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 📡 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_2.0.54 Modem 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.

What ISP Speed UP and Down do you pay for? Might consider updating to v.2 on the RBS first then RBR lastly: https://community.netgear.com/t5/Orbi-WiFi-6-AX-and-WiFi-6E-AXE/RBK750-and-850-Series-Firmware-Version-v4-6-8-2-Available/td-p/2228203/jump-to/first-unread-message

I have an RBR750 and 2x RBS750, firmware 4.6.8.5 in a 2600 square foot two story home. RBR and wired backhaul RBS on first floor, wireless backhaul RBS on 2nd floor.

There will be about 2-3 spots in the house where the connection constantly drops from iphones and wireless devices. I have over 60 devices, 50 of them all connect to the RBR and the rest of the 10 connect to the two satellites. The satellites are all well over 30 feet from the router. I've also tried to decrease the power to 50% transmission and still have the same issue.

The are with the wifi dropping is at corners furthest away from the router, with a RBS maybe 5 feet away. The devices do not connect to satellites even though the satellite is clearly closer.

What are the possible problems and solution to this? The devices do not seem to be evenly split between the router and 2 satellites. Also, I don't think "roaming" is that great on these devices either - seems like if I'm walking between a router and satellite the device drops like a cell phone call being dropped.

    No, still have the two corners of the house where signals drop. This is where I placed my satellites but even though I'm sitting next to the satellite it will still try to connect back to the router 95% of the time. When the iphone connected to the RBR, the signal appears decent (500-700mbps on speedtests) but is not a stable connection it appears. I can't figure out why it won't just connect to the satellite even though I'm sitting next to it.
    
    I'm not entirely sure it's due to poor wifi signal or DHCP having issues again. This has been happening before I setup a separate router for DHCP server. When the wifi symbol disappears on my iphone and becomes LTE, the iphone is still trying to establish a connection to the wifi and the IP address is again something random such as 169.xxx.xxx.xxx.
