Orbi RBR50 Dropping Internet Connection Regularly

[amurrey]

Reading through these posts, the only people that have successfuly corrected this issue was done via a hardware RMA with Netgear.  It's obvious that some percentage of the Orbi devices sold via Costco have a hardware defect that is causing this drop.  I RMA'd my router unit 6 months ago now, and the system has been running flawlessly.  It's not a setting, its not a configuration, its some type of hardware failure.

Thanks ekhalil.   I am on 48 being one firmware upgrade since out of the box but have not done a factory reset. 

[Harryp123]

I just upgraded to V2.3.1.48 and did factory reset on Router (not satelites).

My router is loosing connection to interenet and restart is fixing the problem before. Since router is causing the problem, I did factory reset on Router only.

[ekhalil]

When you loose internet connection does the router top LED turn magenta? Instead of restarting Orbi does disconnecting internet cable and connecting again solve the problem?

[Harryp123]

no magenta color.

In my experience as well, there was no magenta colour ... i assume all of the LAN including the satellites, remains fully connected. I did not try pulling out the internet cable, but going into the internet config page and saving the settings (without changes) brought back the internet connectivity without restarting the router. My internet is of the PPPoE type, in case this is relevant - so i plug the router directly to my ISP's socket without any modem in between.

For me, the internet service would not drop in one shot for all clients - the clients would progressively lose internet connectivity in random order until none could connect to the internet. The problem did not have any favourites across iOS / Android / Windows and across hardware vendors (Apple, Samsung, OnePlus, Dell)

Also, as an observation, i never got the notification for Circle being offline while clients lost internet connectivity. So i assume the Circle service somehow still remains operational, yet the Orbi does not let clients connect to the internet. Don't see how this should be an hardware issue - presumably this has to do with a unique set of local environment variables including possibly the neighbouring wi-fi networks.

What lease time do you have from your ISP? You can find this under >> ADVANCED >> ADVANCED Home >> INTERNET PORT >> CONNECTION STATUS.

[Harryp123]

Why it says Lease Expires in 1 Hours and 43 Minutes?

Lease Obtained	0 Days, 2 Hours, 0 Minutes
Lease Expires	0 Days, 1 Hours, 43 Minutes

[walder]

Sorry i will not be able to answer this straight since the Orbi was decomissioned and now sits in a box. Would it help if i got you the same info from my Asus router which is what i have now?

Yes please. I saw previously that when this time is so long then sometimes Orbi looses the internet connection. We can try to set a shorter lease renewal request time in Orbi as a workaround and see if that can have some improvement.

On the Asus the lease value is 86,400 ... on this i have a daily reboot of the router scheduled for 02:00 so i am not sure if the lease value also gets reset every night. I do not see any lease expiry value.

Please try the following to reduce the lease time:

• From browser go to the router's debug page (http://192.168.1.1/debug.htm). Use your router's IP address or http://orbilogin.com/debug.htm
• Enter admin as user name and your router’s management password
• Tick "Enable Telnet" option
• Use Telnet from a computer attached to Orbi to connect to your Router telnet 192.168.1.1 and enter admin and the same password as above
• Enter the following commands:
• root@RBR50:/# config get wan_lease    — Should give you --> 86400
• root@RBR50:/# config set wan_lease=750
• root@RBR50:/# config commit

86400 means 24 hours

After upgrading and performing factory reset on the router (4/27), today it dropped connection (5/2). Routine, restarting router worked.

Firmware version: V2.3.1.48

Have you tried the suggestion to reduce the lease time? 🙂

[Harryp123]

I don't have an option to reduce lease time. Its not editable for me.

Can you check the log and see what events were logged?

[Harryp123]

I don't see any logs. Here is the logs after restart router.

There is no option to change the lease time in the web GUI. You need to use telnet to make the change. Please see the previous post:

It dropped connection again and here is the logs:

Guys. Stop using the Orbi app! Connect using a computing only for updates and settings mention by previous members and pick a specific channel. Do not put in auto. Then reboot modem and router by unplugging power for at least 3 mins. Every time I use orbi app it causes several connection drops in a day. Now I haven’t had any drops in months. Try it and please update the community if successful over a weeks time period.

For those who have experienced WiFi drops, would you mind sharing your Wireless Settings page?  I'm wondering if there's a pattern or common settings that would cause this issue since WiFi drop doesn't seem to affect all users.  It would be helpful if you share this page.

[Harryp123]

I am using computer to change any settings.

I use Orbi app to reboot roiuter when it disconnects from internet.

Attached my wireless settings page.

Can you find out where this IP address is coming from? 

18.208.129.192

Domaintools.com

Might ask your ISP to change your WAN IP address on the modem...

I am not sure how to check where this IP address is coming from. Reg: "18.208.129.192".

Can you please guide me?

Thanks
