WAN connection continuously drop (GL-MT3000 Beryl AX)

My beryl ax router loses connection continuously, it is connected to a freebox delta (Fibre 1Gbps) via its WAN port and the freebox is in bridge mode.
Everything seems to be working fine, until the WAN interface goes down/up in a few seconds.
I've already tried changing the ethernet cable, changing the port on the freebox, trying different power supplies and even exchanging the beryl ax router, thinking at first that it was a faulty model...
I don't know what else to try... is this model really reliable? As it is, on the 2 models I've tried it's impossible to hold a videoconference, for example.
I'm considering this router for a trip, but I need to be sure of its reliability!

try this

Ok I'll try this solution, for the moment it seems to hold (on 1000 consecutive pings no losses).
But if it works, how can we fix it in a more durable way?
The web interface, for example, after the ssh manipulation concerning interface modification, says that the router has no internet connection via ethernet

This seems to be because the MT3000's 2.5Gwan port is not compatible with your parent network port
Since the MT3000 does not have dual wan functionality, it cannot be displayed on web pages

I'm not asking for a dual wan, I'd just like to avoid the router's configuration web interface telling me that the Internet is unavailable (not connected to the WAN port) when it is...
I'd also like to know why this 2.5G port isn't compatible with my internet box, which is a bridge and works fine this way with other routers or even a laptop on the other end that gets the ISP's WAN IP.
What are the specifications/requirements for this 2.5G port to work stably?
Does the SLATE AX model have the same limitations/incompatibility on the WAN port?

This is for certain switch/modems that cannot link to the 2.5G WAN port(not very common case actually)
The SLATE AX doesn't have a 2.5G network port, so it shouldn't have this problem

Ok now that I understand the problem a little better I'm going to make a last try with a switch “D-Link Switch DGS-1005” between my freebox and the beryl ax with only the router and my box connected to see if this solution works properly even if it weighs down the equipment to be moved for travel.

And with this Dlink switch same problem appear again...
Why ? This is not the same parent network port and device than previous...

Looks like this one has compatibility issues, too
Can you follow the previous method to use first?
we buy a Dlink and test it out


Is this it?

The Dlink switch I just tried is a DGS-1005D like this one https://www.ldlc.com/fiche/PB00021131.html

I'll go back to the suggested configuration:

uci add_list network.@device[0].ports='eth0'
uci del_list network.@device[0].ports='eth1'
uci set network.wan.device='eth1'
uci commit
/etc/init.d/network reload

But I'm not entirely happy about having to use a new device in a roundabout way... then the web interface becomes totally inconsistent because it doesn't follow the changes made in SSH... maybe the web interface would need a parameter to switch the LAN port <--> WAN port ?

It would be very useful (indispensable) to establish a compatibility list of peripherals/protocols with beryl ax, because at the moment I feel like I've bought an unusable product despite several days of debugging/troubleshooting a new device and not everyone has my network knowledge... I thought I'd bought a mass-market product, not a prototype compatible with a handful of devices.

Apology for the compatibility issue about the 2.5G port, as the 2.5G even 10G is a relatively new hardware technology.
They has just begun to use in the mass consumer market (non-tech enthusiasts), probably it exists a little compatibility problem which in the PHY chip. Anyway, sorry about this.

As you mentioned that on using switch DGS-1005D, the ports are 1Gbps, may I know do you consider changing other one GL router with the 1G port?

For the latest news, I managed to hold a videoconference yesterday for 1h without interruption and I can see over a few consecutive hours that I had no packet loss:
20000 packets transmitted, 20000 packets received, 0.0% packet loss
and so for the moment I think I've found an avoidance “solution”...
My “hardware” solution is to interpose a cheap (but gigabit) dlink switch that was lying around in a cupboard...
This way the beryl ax is no longer directly connected to the freebox and the WAN interface (after the first cut shared in my post)
It now seems stable and functional, but it's a shame to lose the ease of transport of the beryl ax solution, as the dlink switch requires a mains adapter and additional equipment...
i'm planning to use this router mainly for travels and so i can't know on which wifi equipment/network i should plug the beryl ax, i'm still hesitating to return the beryl ax and exchange it for a slate ax what do you think?
Can you tell me the pros/cons of beryl ax vs slate ax?

If you use Beryl AX with op24 firmware it should be fine.

Slate AX is using Qualcomm chipset. It comes with open source wifi driver when born. So in both hardware and software it looks more stable. But Beryl AX is improving.

Sorry for raising on old thread but has there been any update on whether GL.inet will ever add the functionality to change the LAN port to a WAN port within the UI?
This function would be really helpful especially when some of the modems don't like the 2.5 g port
Thanks
