Orbi RBR760, guest network, giving improper IP and subnet

I recently bought and installed from Costco the Orbi RBR760 (router) and 2 RBS760 (satellite).  

It's running firmware version V6.3.6.4_1.2.68.  

 

Guest network setup and running without issue for a bit   But then a few devices that are using on the guest network will connect but won't receive proper IP and subnet.   Items that are working are connecting to 192.16.2.x/24.    When I get a bad connection on the guest wifi, it connects on 169.254.x.x/16.   I have no clue where it's picking this up from.    If I change the wireless SSID, it seems to work for a bit and then has same issue.    Once the device has this issue, it can't fix it for that particular SSID.   

 

Has anyone run into this problem and found a solution?

Problem resolved.

I had Orbi cancel the "Parental control" feature.      This gave me back the "Access Control" section on the web administration page.  Once I turned off all the Access Control, the problem went away.   Now I need to learn a bit more on how Orbi's access control works.

Additional info:   I'm running the router as a router, not using AP mode.   I have Verizon FIOS and a direct Ethernet connection from the ONT.

For Guest Network IP addresses, the network does use and would be expected to use a 192.168.2.x IP address string. This is expected behavior since the GN is separate from the main LAN network.

I agree.   Those devices that pick up 192.168.2.0/24 work fine.   Some devices are picking up something completely outside that address space.   Those devices can't access internet.     I can't figure out how or why they are picking up wrong IP range.

Re: Orbi RBR760, guest network, giving improper IP and subnet

The 169 is a APIPA address, a self assigned address that the system seems to be detecting when the normal DHCP didn't get the device a correct IP address or the device didn't correct handle the IP address given by the DHCP server. Normally the system should be able to hand out a 192.168 address to the device. There is a problem with the device or between the RBR and the device. 

 

How many devices are you connecting to the GN? 

BE aware there is a short time frame on when GN is working for connected devices. This is a based on historical design that the GN devices are only connected for a short period of time then the lease time expires for the guest device. Something users don't keep in mind. GN was not intended to support long term connections.

I would reset the connecting device as well to see if this help the device get a proper IP address from the RBR.

Re: Orbi RBR760, guest network, giving improper IP and subnet

169.254.x.x/16 is a "Link Local Address" which a device creates for itself when it does not receive an IP address through DHCP:

https://en.wikipedia.org/wiki/Link-local_address 

 

I would try to connect these devices to the primary WiFi SSID and "see what happens".

Is it possible that Access Control has been enabled on the system?

(perhaps without meaning to.  you laugh, but it has happened to me.  Spent an hour fighting with a device only to find that Access Control was ON and set to "Deny Access to new devices")

Excellent information!  I didn't know about Link Local Address.

 

Now to turn off the Access Control.    I enabled Parental Controls for thee trial period.    I found its more trouble than it's worth.    I have requested customer service to turn it off since it's only controlled through the app now.   I tried to get rid of all profiles and make sure everything has full access but my devices still aren't happy on the guest network.   I'll keep messing with it.

Thanks again for your help and getting me on a potential track to a solution.

Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
