Orbi RBR50 keeps going offline but speedtest in app keeps working

[saurabhchopra]

My RBR50 has started going offline every couple of hours. The weird part is that the speedtest in the Orbi app shows connectivity and can do a speedtest. However, the router page shows the router as offline, and the internet does not work on any of the devices connected to the orbi (both wired and wireless).

I have tried doing a factory reset, rolling back the firmware (went from 2.7 to 2.6), assigning static DNS, but it hasn't helped.

Restarting the device makes it work for a couple of hours (sometimes less than an hour), and then it goes offline again.

Any idea how I can fix it?

The reports started coming in immediately after Daylight Saving Time went into effect.  Some very bright users determined that Orbi was no longer resolving Domain Names.  Any time a program tried to access an internet resource by name, the DNS feature would not look up the IP address that is associated with the name. People found 6-7 very creative ways around the problem and knew it had *something* to do with Daylight Saving Time.  The revelation that Traffic Meter was confused by Daylight Saving Time and somehow broke the DNS process was a real surprise.

The issue only affected users (a) with specific firmware versions (not all versions have the flaw), (b) "automatic" Daylight Saving Time activated, and (c) Traffic Meter enabled.

If disabling Traffic Meter does not solve the issue, please let us know.

There is an ongoing issue with Orbi firmware involving a combination of Traffic Meter and Daylight Saving Time.

(at least a dozen posts on the forum.)

Please look at the Orbi web interface, Advanced Tab, Advanced Settings, Traffic Meter and uncheck the box "Enable Traffic Meter" toward the bottom of the Advanced Settings menu).

removing log also solved an interrmettent problem that started a few days ago. The router appeared to be loosing the ability to resolve addresses.

Will wait for an update.

Many thanks to those that found that solution!!!

Changed the NTP settings like this.

Solved the problem immediately.

Advanced > Administration > NTP Settings

Uncheck "Automatically adjust for daylight savings time"

Set your preferred NTP server to time.nist.gov

Works like a charm for the last 4 days.

I too disabled daylight saving time as well as traffic meter a couple of days ago. It seems to be working well since. What firmware are you using btw.

I had rolled back the firmware to 2.6, but will upgrade back to 2.7 this weekend if that works too with the fixes above.
