I would say „Case closed.“ because the speed seems to be very dynamic with StarLink.
So you should check if the position of the antenna is optimal. Seems to be not an real issue with the router itself - maybe just coincident.

You are on the speed of your contracted plan (the upload is even better).
Keep in mind that Starlink is a service for remote areas. It's the last option to choose.
Sometimes you can reach high speeds, but it's an exception and not the standard.
I think you should return the router while you can, get something else and don't look back
Summary
All this starlink talk it's making sick and I know I'm not the only one
Now the speeds here in my country are significantly higher. The standard here is 200 to 250 mbps, as any of my neighbors will confirm. But it's okay for 50 euros.
That's not the point. The speed drops down to 5 or 10 mbps only occur with the Flint 2 router.
This doesn't happen with an Asus AX86U. From my point of view, the Feler can be found in Flint. It's also strange that after restarting the Flint 2, it regains performance and slowly becomes slower again over the course of hours. Until the next restart.
Don't forget Starlink won't be restarted in that time so it can only be Flint's fault.
"I emphasize again" It's not about the final speed but about slowing down and no longer increasing the speed.
This is a new replacement device because the first one was completely faulty.
Amazon kindly replaced it
Again, sent it back and get something else
It is possible the asus router dynamically change the mtu, usually that is as expected.
On the Flint 2 im not sure if that is a bug, but on all interfaces the mtu seem fixed to 1500 if you look into luci inside the network settings (devices tab).
And to be honest i don't know why that is in DSA such devices like lan1, or eth0 don't need to be configured only br-lan should be, this is how OpenWrt would do it without the gl software.
Then the kernel manually adjust/change mtu on overhead also on more complex situations when you look into multi tunnels but that is for now not the point it brings in confusion.
But that is the only difference ive seen what might could cause this effect.
Sorry, but it's not true.
In fact, it's the oposite. The Starlink speeds in Germany are sligly slower than other countries in Europe.
The screenshots and links I showed to you before are an oficial specification from Starlink.
Also this one:
They also says: "...Actual speeds may be lower than expected speeds during times of high usage..."

But you already know that my problem isn't about the internet speed, right?
OK, let's try in this way: call Starlink and say to them that your internet is reducing the speed over the time, going down to 10Mbps and let's us know what they told you.
You had read the section where I wrote that if I connect another router the internet won't slow down???
what happens if you unconfigure the DSA devices and let DSA handle MTU? (Yes keep br-lan intact).
One issue is that most (wifi) wireless connections use half duplex and not full duplex i think it is no difference over satalite, and this can affect not only just layer 2 but also the size of the jumbo packets (MTU).
However the gl software automaticly configure the DSA devices with 1500 mtu.
When i check this post:
I see that OP have similar commonalities with @Funnyland.
The packet loss is really a abnormality without hard proof of evidence from diagnosis i refuse to believe its just being done of as a unstable connection by starlink.
Ive already sent a couple of messages here with tracerts and pings, but nobody post any result.
I just want to see if it is replicable between around the same packet counts, and eliminate if it is a hardware issue to Starlink (?), a internet exchange peering issue (?), or like this here a half duplex mtu problem.
Wouldn't it be better to start a new thread about starlink problems?

I highly agree. I would even say this monster thread should be closed, and not every topic related to the MT6000 should be discussed here.

Starlink isn't even the problem. They only deliver the internet.
I'm just not entirely sure whether it's understood that it's not Starlink that's the problem but the router itself.
Starlink is just the internet provider and it works.
"It's the Flint of the 2 that works slower and slower after a certain time"
I've written that several times now. If I connect another router (test model Asus Ax86U) behind Starlink there are no problems. Everything is going, nothing is slowing down, etc.
Which suggests that it can only be the Flint 2.
I tried almost everything I found or thought of across all the firmware, endless settings and a wide variety of MTU settings. Unfortunately one success.
Have you also tried on luci via network -> interfaces and then click on devices tab?
Please unconfigure these except for br-lan, you may want to reboot to be extra sure.
^ then test without vpn, because if you use tracert and test packetloss with ping between the hops, you want the route to the internet via wan and not from the tunnel.
As for pinging, you can try something like 100 packets between each hop, if you see a replicable pattern of packetloss that can point to either big jumbo packets mtu loss, or starlink router has issues (you will find this out at the hop it happens), when it is even far beyond it might be a internet exchange peering issue.
^ this way you can pinpoint and map where the problem occurs which can tell more what is going on, also fragmentation messages can tell the mtu is too high.
often you want to look to a pattern which really goes out of bounds, From 200 ping to once of a sudden 1000 or even better a time out.
Sorry, but unfortunately I don't have a plan for what you want.
Unfortunately, my question regarding the Flints 2 router has now been moved to a VPN thread, whatever that means.
Since the question concerns the router.

It also bothers me that the router isn't working properly. Still, keep my frustration to myself. Just looking for solutions, I don't enjoy it either.
On the third comment above, people offered help to debug, but you said "...I don't have plan to do what you want..."
So, I can only say that your Starlink is giving you what are you paying for:
