TWO ISSUES FOR ORBI RBK852

And id you change those or were they already set to these values? 

How is your Orbi AX system doing? Noticing anything? Hoping it will be stable now. 

Hello, I reset my orbi, and setup . The default CTS and RTS value is 64.

I think the reason for 5g wifi(satellite) unsecured is the following:

1. RBK850 is connect to internet via dhcp(not pppoe)

2.You add RBS850 later(not in the website setup routerlogin.net) 

I think someone could reproduce this isssue easily.

If you add RBS850 during the website setup, the 5g wifi is secured.(RBK50 is fine if you add satellite later)

I would change the CTS and RTS to 2347.

So adding the RBS via hitting sync button on RBR and RBS is causing the problem on the RBS? 

Yes, I think so, as long as you add the rbs later(after set up the rbr850). Another condition is you use dhcp to get internet(not pppoe,in router mode)

BTW，I see the magneta light up this morning for about 10minutes, I check the log, and see the following,

I don't know if this is related to the default ntp server, I will change the server to see what will happen.

So adding the RBS during the RBR set up seems to not have problems? 

Sounds like something isn't getting thru from you host router to the RBR in AP mode. 

What is the Mfr and model# of the ISP Modem your using currently? 

What would happend if you can replace the host router with the Orbi AX router and configure it for router mode? 

1. Yes

2. I am trying  to repeat the unsecured 5g wifi issue, if you restart both rbr and rbs at the same time, could result in the satellite open 5g wifi.If you restart rbr first or rbs first, it is ok.

What is the Mfr and model# of the ISP Modem your using currently? 

What would happend if you can replace the host router with the Orbi AX router and configure it for router mode? 

1. Huawei MA5671 Fiber Modem- Ubnt ER4

2. I can't do that due to limited space.

I think I noticed an obvious issue during the setup process. You could see open netgear-guest wifi sometimes. Even the guest wifi is off in the settings. It will disappear after orbi reboot. I think this isssue is related to the unsecured 5g satellite wifi ( probably same bug code in the system)

Sounds like it might be something with you configuration as well. 

Something I haven't seen however I have Cable and DHCP for ISP services. 

I know with recent FW that AP mode seems to have proablems with RBS being wire connected. Today I tested both wireless and wired LAN cable direct with out any swithces and the RBS connected correctly. IF there is a switch in between the RBR and RBS, the RBS doesn't report correcty in the UI. Thought it seems to be working as I get a BLUE LED. 

So if you setuo the RBR correcty first, the add the RBS later, the RBS is correctly connected and is secure?
