@David-TP 

Thanks for the clarification on IPv6, but I still think supporting larger delegated prefixes more fully would be a valuable improvement for advanced IPv6 deployments.

As for the Linux kernel, I could not find official download links for previous firmware versions, so I am unable to compare or roll back. Because of that, I cannot tell whether the kernel base I observed is specific to this beta only, or also used in stable/final releases.

Thanks,

@David-TP 

I share the same feeling as @natszirt 

While these may be different IPv6 issues technically, they seem to expose the same limitation in Deco: IPv6 is supported, but advanced control and observability are still very limited.

Whether the issue is delegated prefix handling, MTU/PMTUD behavior, RA/default route visibility, or general troubleshooting, the current UI exposes very few IPv6 parameters compared with IPv4.

It would be very valuable if future firmware added more IPv6-specific controls and diagnostics, not just basic connectivity.

Option 2 is:

Let the Decos as AP and buy a router 😔

Thanks again 

Hi all,

@David-TP 

After updating to the beta firmware, I am experiencing serious compatibility issues between my Deco XE75 V2 setup and several legacy or non-Wi-Fi 6 devices.

The affected devices include:

-Samsung A04

-Samsung A26 5G

-An old Samsung TV with Tizen and Wi-Fi 5

All of these devices are able to connect to the Deco network, but their download speeds drop to below 1 Mbps, making normal internet use almost impossible. The same behavior appears consistently across all three devices.

I have already tried the following without success:

disabling 5 GHz and 6 GHz

disabling Beamforming

disabling Fast Roaming

creating a Guest Network

lowering security to WPA2

None of these changes solved the issue.

Current setup:

-ONT 940mbps FTTH

-Deco XE75 V2 as main router using PPPoE

-switch + wired backhaul UTP Cat 6.

-2 additional Deco XE75 V2 units 

At this point it looks like the beta may have introduced a compatibility issue with older or non-Wi-Fi 6 clients.

All other wifi 6 clients are working with no issues even connected to the same Deco unit.

Has anyone else seen similar behavior, or is there any recommended workaround?

Thanks.

  @David-TP hi and thanks. Yes, I received your email and I will reply with the details.

Thanks again for forwarding the case.

I am having the same issues described by other users after updating to this beta version

Network of 3 XE75 connected as routher in mesh mode, with 2,4, 5 and 6GHz activated

- Some devices connect but with 0 bandwith (mainly Samsung phones, but also a Dell laptop and a PS5)
- Other devices workinhg with no problem (Pixel Phone, severa xziaomi phones and tablets, and IOT devices connected to the IPT Network) 

- There are several wired devices that work with no problem

- Wireless backhaul seems to be working with no problem

To solve the problem I have had to get my Deco M5's out of the storage box and connect them as a paralel network in AP mode and the Samsungs and the PS5 are connected to it and working with no problem.

  @David-TP And the problem I had with smart TVs?
