Orbi RBR50 intermittently dropping internet connection

[A1406]

Hello,

I am having issues with my RBR50 intermittently dropping our internet connection. It seems the router might be restarting at what seem like random times causing a WiFi disruption. I've looked into the logs, but a restart also seems to erase all log entries prior to the restart. The connection is restored after the RBR50 reboots. I updated the firmware to the most current version (2.7.2.104) and this did not fix the issue.

Any advice on how to continue troubleshooting?

Get rid of 2.7.2.104

The issue occured prior to the firmware update, so while that could be contributing factor, it's likely not the root cause.

Or is there a way to confirm it's the firmware causing the issue? Is there a more stable version I should download and apply? Does netgear even give access to previous firmware versions?

The problem was happening before firmware was updated to 2.7.2.104?

It would be useful to confirm whether the Orbi is (a) dropping the network connection, (b) the Orbi is restarting, or (c) the Orbi remains on line but has quit providing WiFi. 

• When the Orbi restarts, the Orbi log is reset (empty), whether it restarts by itself or the user restarts it (power switch, reset hole, etc.) Can you look at the Orbi log file before attempting to restart the Orbi yourself?
• If only the internet connection has dropped, then devices should continue to connect to the Orbi WiFi, but be unable to "do anything" on the internet.
• If the internet connection remains good, but WiFi has dropped, then a device connected to the Orbi with ethernet should continue to function correctly.
•

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

Please try a factory reset and setup from scratch with the RBR and RBS.

Go to the download section here and enter your model number.   

do a search here on 2,7.2.104.   Lots of complaints

Yes, this was happening before updating to 2.7.2.104.

Agreed, what you're proposing makes sense. My sense is that it is (b), but I am not yet 100% sure. 

• Yes, I can do that. What information would be useful that I can provide?
• I believe I am losing connection to the Orbi and it is not that the internet connection has dropped.
• I have some home entertainment peripherals hardwired to the Orbi, but so far this has only occured while I am working on my laptop which is connected via WiFi (which drops when the issue occurs).

I've found where I can download previous firmware versions. Is there a version I should apply that is generally accepted as stable?

[vajim]

If you can't remember your last stable version try one back

tip.....stop performing firmware updates

I have fiber optic service through Sonic and the modem was installed in a way where I cannot see the mfr/model#. I will have to reach out to them for this info.

I will try a factory reset and setup from scratch.

[FURRYe38]

Ok, only checking to see if there is a router at the modem or not. These can be problematic. 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.

Keep an eye on that firmware 

[A1406]

@FURRYe38 @CrimpOn 

I havn't yet had a chance to factory reset and re-setup the RBR50, but something happpened last night that could provide some insight.

I was playing Xbox (which is hardwired to the RBR50) and the internet connection dropped/I was disconnected. The RBR50 LEDs then went to solid white, stayed solidly lit for a bit, then went to pulsing white. The connection was then reestablished.

Does the fact that a hardwired peripheral lost connection and the LED info/behavior provide any clues?

[vajim]

if you're still running 2.7.2.104 it might

[FURRYe38]

Were you able to find the brand and model# of the ISP Modem the RBR is connected too?

Besides the xbox being connected to the RBR, is there any other wire connected devices with the RBR? 

Possible that the RBR saw a quick connection problem between the RBR and Modem and wasn't long enough to show PINK and the RBR soon recovered the connection with the modem...

I have two xbox consoles connected to mine...

The Orbi log may contain a clue if there is an entry at the time of this event.

I have not heard back from my ISP about the modem brand and model.

Besides the Xbox, there is an Apple TV, Network-Attached Storage (NAS) device, and a Sonos speaker hardwired to the RBR.

Would my ISP be able to determine if this is caused by quick connection problems?

It looks like the log was deleted again after the RBR rebooted.

I do see A LOT of "attacks" logged. I've seen this in the past, googled it, and found that it seems to mostly be the RBR miscatagorizing pings, but I've always been a bit uncomfortable about this. Previously the IP addressess were from Amazon. Attacks catagorized as the following:

[DoS Attack: TCP/UDP Chargen]
[DoS Attack: SYN/ACK Scan]
[DoS Attack: RST Scan] 
[DoS Attack: ACK Scan] 

[FURRYe38]

They can see if the modem or there services have seen any odd problems from there logs, should be able to. 

Do you know if ther modem has a built in router and wifi or is it just a stand alone modem?

The modem is a standalone unit. No built in router

Looking at what the RBR LEDs indicate, would a quick disconnect from the modem cause the RBR to reboot?

Solid white = Orbi router is powering up.
Pulsing white = Orbi router is in factory default mode. 

[FURRYe38]

OK Thanks for that info...

With Orbi anything is possible. 

I would try the factory reset and setup from scratch when you get the time.

I'll have to wait for this weekend for the factory reset. Will let you know how it goes.

I do see A LOT of "attacks" noted in the log. I've seen this in the past, googled it, and found a lot of posts mentioning this could be the RBR miscatagorizing pings, but I've always been a bit uncomfortable about this. Previously the IP addressess were from Amazon. Attacks catagorized as the following:

[DoS Attack: SYN/ACK Scan]
[DoS Attack: RST Scan]

Any thoughts on this? Should I be concerned?

[FURRYe38]

Yes been lots of info about how Orbi miscatagorizes these log entries. If your checking on the IP addresses and there from places like Amazon and Google, then these can be ok. Those kind of depend on what devices and what services your accessing as well. 

To try and help narrow some of this down, if you can find the time, turn off everything accept for the RBR and one wired PC. Clear the log on the RBR. Close all apps on the PC and check the log enteries for a short period of time. Also check the behavior as well.

Then start turning on devices. Check the log as you go. You might notice enteries start to populate maybe at some point.

I think not.  When I remove the modem ethernet cable from the Orbi WAN (yellow) port, the ring light turns magenta.

The Orbi remains "alive", still broadcasting the WiFi SSID.

[FURRYe38]

Would be a good test try. Like @CrimpOn said, it should not reboot if you try that:
