Available here: RBR50 / RBS50 Firmware Version 2.6.1.40 | Answer | NETGEAR Support

New Features and Enhancements:

When there are no user issues fixed does that mean there are no user issues to fix?

Is this official or beta firmware ? I just updated to 2.5.2.4 2 days ago !

[DatabaseJase]

I'm not sure if it has a "beta" tag but it is official and as far as I'm aware NG don't do "beta" public releases...

The "New Features and Enhancements" section is confusing:

Supports HTTPS on the LAN

What should that mean ? If I'm using https internally, then I use it and it is already working (browser and REST calls).

Anyway, I reverted from 2.5.2.4 to 2.5.1.16 because this is the most actual FW which is working on my environment (1 RBR & 1 RBS wired and 2 RBS via backhaul).

Would be interesting, if someone already upgraded to 2.6.1.40 and what the experience is ?

- are the connected Devices displayed correctly (mobile appp & browser)

- stability

Experiencing issues when loading up ebay.co.uk after the update. Any device connected to the network cannot seem to load up the css for ebay.co.uk

[timch]

I've been running this for about a week or so with no problems; it seems really solid and the app works as expected.  I've checked eBay.co.uk just now and it's loads perfectly.

I have an RBR50 and 2 RBS50 connected wirelessly and an RBS40 connected on Ethernet.

Thanks for sharing your experience.

Just a few questions to your setup:

- are you using the Orbi system in Router or AP mode (i use Router Mode)?

- Are you using "Access Control" ?

- Are you using "Port Forwarding" ?

- Are you using "Dynamic DNS" ?

- Have you configured "VPN Service" ?

- Are you using "LAN Address reservation (bind MAC to a fix IP address) ?

- Have you done a factory reset after the upgrade ?

I'm really scared about upgrading, because I made really bad experiences with FW after 2.5.1.16 and a factory reset of the system leads in a lot of work to reapply the configuration (or I load the config backup).

From my point of view, the usual suggestions to do a factory reset after an upgrade is a pain and should not be necessary.

Would be great if you can give me more details about your working setup. Then I could estimate if an upgrade is worth it.

My setup:

RBR50 and 2 RBS50 connected wirelessly and an RBS50 connected on ethernet

I'm using the Orbi in AP mode but I've never done a factory reset in all the years I've had my Orbi, and I have tried both modes.  I use AP mode for convenience only. 

[Ha_Ku_Na]

ok, thats a difference, and includes also that you cannot use all these features:

- Access Control

- Port Forwarding

- Dynamic DNS

- VPN Service

- LAN Address reservation

Hello All

Quick question in relation to firmware update to 2.6.1.40:

I am currently on 2.5.1.16 so should I first update to 2.5.2.4 or can I direectly update to 2.6.1.40?

Thanks!

[FURRYe38]

You can directly. 

[faizankhan85]

Thank you for your fast response!

[FURRYe38]

Apply the RBS first first, then RBR. I would power OFF the RBR and RBS for 1 minute then back ON after the FW has been process by the RBS and RBR.

RBR50 and RBS50 Firmware 2.6.1.40 just update manually, update smoothly , all connected device show properly, vary stable. Thank You. for provide update firmware continuously. 

[Ha_Ku_Na]

Could you please also post some deatils of your configuration ?

like:

- are you using the Orbi system in Router or AP mode ?

- Are you using "Access Control" ?

- Are you using "Port Forwarding" ?

- Are you using "Dynamic DNS" ?

- Have you configured "VPN Service" ?

- Are you using "LAN Address reservation (bind MAC to a fix IP address) ?

- Have you done a factory reset after the upgrade ?

Because I think the mode can make a big difference regarding stability. 

I use it in Router mode because this makes it easier to change the internet provider. 

[FURRYe38]

Well, wanted to try v40 on my RBK50 series with the RBS50 ethernet connected. 

ARP storm is happening on v40 as well...

ARP Storm with v40:

Downgraded to v16 which was working well last time...

No ARP Storm with v16 loaded:

So I recommend for users of the 50 series Orbi who have RBS ethernet connected with a switch or more, keep v16 loaded. Hopefully NG can fix this in future updates.

"Security issues" is "user issues".

You login over HTTPS by default, which is a good security practice that they didn't follow up to this point.

My issue with it: 2.6.1.40 changed my password and I can't login into it any more...

[FURRYe38]

Besure to clear out all browser caches before going to the RBRs web page.

Be sure your typing in the correct PW values.

Try a different browser to compare.

Factory reset the RBR and setup from scratch as last resort.

I never type the password manually, I use a password manager.

I had to do a password reset by manually introducing the serial number.

[FURRYe38]

Try manually typing in it to be sure.

Hi,

I have same ORBI setup at home RBR50 and RBS50.

I never done any manually firmware updates, I always use smartphone app to check for updates and then update them if available.

My current version is 2.5.2.4 and smartphone app is not showing me this new update if I use check for new updates. It is showing my firmware is up to date.

But it is clear that Netgear has relased this version 2.6.1.40 which i can see in their download section as well.

SInce my app is not showing this version does it mean this is not mandatory version for me to upgrade?

Cheers,

JM

Nothing is mandatory unless pushed to the device by Netgear without user intervention.  That happens very rarely.

You can check the release notes (which doesn't say much), and security bulletins at https://www.netgear.com/about/security/ and see if you are up to updating the devices manually following the instructions here

Meaningless ....why post this here?

Shouldn't this go to firmware developers ??

[alokeprasad]

This is a rare instance when NG has documented a problem and the fix for it.  Lets not fight it.

Making users aware of this is a a good thing. This way, users can look up the details of the security issue, decide how serious it is, and whether to update their firmware to 2.6.1.40 or newer (for RBK50's).
