Orbi RBK852 4.6.3.16 broken (Solved)

This topic is only for the Netgear Orbi RBK852 / RBK853 / RBK854 / RBR850

Introduction:

I bought my Netgear Orbi RBK852 last year. It's work fine and I am happy with that until they release 4.6.3.16 firmware and my router automatically updated on it. Wifi ,Internet keep dropping. DNS server can't be reached, DNS found the domain but the internet didn't work and can't reach the website. I spend about 2 months try to fix this problem and neraly made me crazy. I resetting and restarting the router so many times. Downgrading my firmware to 4.6.3.9 but it just automatically updating to 4.6.3.16 and the problem just happen again. Calling the netgear customer support and they just let do many setting changes. Calling the ISP checking the network modem. Bring the router to the repair center and they said there are no problem on the hardware but they also gave me a new one for replace. But none of them solving my problem. Until today, I call the customer support and they gave me a new firmware (4.6.5.14) of the Router (RBR850). 

My problem finally solved. Below are the step how I made everthing running smooth again.

Intsalling new firmware:

Step 1: Please download the firmware RBR Firmware 4.6.5.14 (This link and the firmware is providing by the netgear customer service and 100% safe. If you still didn't belive on these you can just leave)

Step 2: Unzip or just pull out the RBR850-V4.6.5.14_2.0.54T4-signed-11041358.chk file out and remember the path where you extract, we need that extracted file later

Step 2: Head into the https://orbilogin.com/

Step 3: Login to your router.

Step 4: You will able to see BASIC and ADVANCED tab, click on the ADVANCED

Step 5: On the sidebar choose Administration

Step 5: You will see a drop down list. Choose Firmware Update

Step 6: In the Firmware Update tab you will see Online Update and Manual Update

Step 7: You will see a tiny words (To update Orbi router, locate and select the update file on your disk.)

Step 8: Click on the Browse icon and find the .chk file you just extracted and press Open

Step 9: After you choose the file simply just click on the Upload icon. The router will immediately starting the update. But this is not the end after you sucessfully update back to this guide please

Step 10: Login to the https://orbilogin.com/ again.

Step 11: Backup all the setting using your way. We need to resetting the router.

ATTENTION : Don't using the Backup Setting to back up your configuration. In my case, restoring the router using the back up file from you router will let the disconnect problem happening again. 

Step 12: Using the hard reset method on the router. Find something that thinner than the resetting hole on your router and pushing the button in the resetting hole about 10-15 seconds and the router will start resetting (Make sure your router turned on the router).

Step 13: Restoring and applying the setting you just backup by your way.

Step 14: Enjoy!

Q&A:

Q: Is the firmware file and link safe?

A: 100% safe

Q: Why there are no firmware for Satellite? 

A: I don't know. The customer service said that there are only a new firmware for the router only

Q: How can I know this problem is the firmware problem but not my other device or hardware error

A: I am asking ISP to check my network and they told me that the network didn't having any problem. Changing another router(TPlink Deco M9 Plus) is able to solve the issue. Netgear repair center said that there are no problem on the hardware and brought me a new one but the issue still going on. At last, I focus on the firmware. When the wifi and internet disconnecting. I am not able to login to my router and pinging the router will having packet loss.

Q: There are some other on xxx steps. Can I just do it on my way?

A: Of course you can do it on your way. The router is belonging to you. But don't ask me why the router still getting problem adngot some other probem after all.

Q: Will this guide 100% solve the issue?

A: I can't really sure about that. But just have a try if you still didn't get any useful information or way to solve the issue that I describe

Q: Will that firmware (4.6.5.14) borke my router / letting other feature being broke

A: I can't 100% sure on that. I still didn't test on the VLAN, Block Sites, Block Service, AP Mode and IPV6, Speed Test. But these firmware actually fixing the issue that I met. I am happy with that now. But I can sure that router mode, port forwading, internet speed, stability, Address Reservation is 100% working.
