RBR850 / RBS850 losing internet connection from Modem

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.

Enjoy. 📡

Update:

Netgear RBR850 lost internet connectivity again, just as before.

This is despite the firmware update documented in this thread.

No other device was attached to the Modem at the time, strictly the ethernet link from the modem to RBR850, which has worked fine for roughly the first 8 months of operation.

The RBR850 receives an IP address from the modem, and then creates local (10.0.0.X) addresses for the various devices. No clue why it started to lose connectivity, and I have verified that the modem is still providing access to the internet.

So unfortunately the original issue is still not resolved.

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Have you tried putting the RBR850 in AP mode?

I have the same issue, I have the RBR852, router with a satelite. The more devices that are connected, the more unstable. Suddenly, like 1-2 times a day, the internet connection is gone for 30-60 seconds max. I've checked with my ISP and when it happened, and it wasn't the modem that lost connectivity. The RBR852 is all wired, no wireless backhaul. Both wired and wireless devices loose connectivity. I've tried the lastest firmware also, no luck. I'm close to deciding if switching out the RBR852 to something entire different, is my solution. The logs doesn't tell me much. It's as if it soft reboots and hands out MAC addresses again. Uptime is also reset. I don't get it. Can't see any valid options in admin that can help.

What Firmware version is currently loaded?

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?

Try a factory reset and setup from scratch?

Running with firmware on both router and satelite: V4.6.7.13

I'm not 100 % sure, but the modem is a Icotera i6901. Running 1000 mbit, not sure what mfr is, sorry? 

I had a power outage not so long ago where all was off for 5 minutes, but I could try again tomorrow.

Haven't tried a factory reset - just the thought having to re-set devices... 🙂

Did you happen to see this issue prior to the v.13 FW update?

Yes, I had the issue before flashing to latest firmware. I hoped the update would have solved it in some magic way.

OK, good to know, what version did you have loaded prior to v.13? 

Is this similar to your modem/ONT? https://icotera.com/products/fiber-network-termination/p2p-ftth-i6900-series

I believe it was the 4.6.3.16.

Yeah looks like my modem.

Ok thanks for this information. I've passed this on to NG for review. It's being tracked currently. 

That's awesome, thanks alot for the fast help and responses.

Thank you for giving feedback. I have been tracking this as well on my system along with others and have made NG aware of it. Don't of know when a fix or a resolution will be forthcoming. Will keep on it with NG. 

The modem Mfr is Orange (France) and the modem info is on this link:

http://cdn.woopic.com/v1/AUTH_c10f167280f2414abb346a5347e1ecd9/prod/binaries/files/827753_21161607_2_Guide_Livebox5_Ed1.2a.pdf

But here is an update, and I'll try to be brief.

- After the lost connection and pink light on the NG today, instead of doing a reboot all around, I simply plugged in my Mac back to the modem (it wasn't on the network when the disconnect occurred): the NG reconnected! Pink light stopped, internet connection re-established between NG and modem. Weird. 

- So I met with a network tech from my work later today. We are suspecting that it may be after all how the NG interacts with the modem (remember, the firmware update had no impact it seems).

- For reasons I have explained above, I need to attach my Mac to the Modem and the NG to the modem, although the NG is the main router for the house (and the only source of Wifi).

So, what we have tried first:

1. assigned on my modem a static IP, one for the Mac and one for the NG

2. reduced the First/Last IP range of my modem (not sure why but he recommended this)

Will see if this works/helps, simply locking in the IPs of the two hard connected devices to the modem (Mac and NG)

So, the IP chain looks something like this now:

- my ISP gives me a fixed public IP (perhaps unusual for ISPs?, but Orange does this in France)

- my modem has of course a gateway (local) IP address (192.168...X) and now a more limited IP range it offers, one of which goes to my NG and one to my Mac.

- my NG has now this fixed local IP address from the modem (192.168...Z)

- my NG assigns all local (LAN) IP addresses to every device in the house (including one of course to the Mac when the Mac is on wifi, which normally works fine in the MacOS world), and these are in the order 10.0.0.X.

The tech said we should start with this and see if this keeps things more stable between modem and NG. Will see.

Thanks for the update and detailed information. Keep us posted on how things go. 

Thanks Furry.

I suppose there may have been some issue as I docked my Mac and undocked it, effectively switching it's internet network and IP from NG (10.0...Z) to modem (192.168...Z). 

But in the MacOS world, all of my past experiences and what I have read suggests this works just fine...MacOS prioritizes upon such a switch and based on preferred order I have set, and it knows to use modem/ethernet for internet access, but then use wifi for Airplay, Airdrop, etc.

That has worked perfectly for years, at home, at work.

The disconnecting NetGear Router started relatively recently.

Let's see...

I don't believe that would effect the RBR loosing connection with the modem. 

Something you can help us with. Open up the RouterIPaddress/debug.htm. 
If you can check this on a daily basis and let us know if you see the Uptime change on the RBR. Also please give CPU and memory usage values if you can. If the RBR is loosing the connected to the modem by chance, the RBR could be rebooting randomly. The uptime value will show the RBR rebooted for unknown reasons. 

Ok.

but where would I find this RouterIPaddress/debug.htm?

Do I look at a log on the interfaces of the router? modem? both?

Yes just look the debug web page in a browser.

Here are some instructions to find the IP address of your router: http://support.routercheck.com/Netgear/Orbi+Satellite/GetIPAddress-0.html.  Once you have the IP address, in your browser and visit "[the IP address you found]/debug.htm".
