Hi@5Guru ,

 

So, are you experiencing different 6GHz speeds on the Archer BE800 when connecting it to different LAN ports on the modem? And is the 6GHz speed actually higher when connected to the modem's 2.5G port?

Have you checked the router's wired speed when connected to the 2.5G port?

 

Of course, we respect your choice. I will reply here if there are any updates.

Yes, wired speeds always go maximum.
10 Gbps, 2.5 Gbps or 1 Gbps on my modem.

In the past, using the BE800 worked perfectly as fibre-WAN modem as well. Always full speeds.

 

And yes on the 2.5 Gbps port the WiFi speeds stick around 1100-1300 Mbps upload instead of dropping to 400-500 Mbps upload.

Download is always LAN port max ~3800 Mbps, my isp speed. ~2370 Mbps 2.5 Gbps port max. ~940 Mbps 1 Gbps port max.

 

Another complete unrelated thing:
Login into this forum, even when you press Remember me, you need to login very often all the time.

Very annoying, pls fix.

Finally managed to replicate the problem exactly and find the source. 5Guru, thanks for the tip.
Internet Port Negotiation Speed ​​Setting in BE800 definitely doesn't affect the speed of the SFP+ module.
Even if I manually set 100Mbps Full Duplex in BE800, the speed on the Mikrotik is always 10Gbps.
I also suspect that changing the Flow Control parameters might not make any difference, but unfortunately I can't verify this. Changing Flow Control in any variants in the Mikrotik and BE800 doesn't affect upload speed.

Solution.
My SFP+ OEM Module only has 2 speed options:
- 1G baseX
- 10G baseSR LR

I manually set the speed on the Mikrotik side to 1G baseX (since this setting didn't work at all on the BE800). And everything immediately improved, with a full upload speed of ~940 Mbps.

 

I'd like to do some more testing in the future with a 10Gbps copper module.

 Hi @5Guru ,

Regarding the feedback on Community login, we have reported it to the relevant departments and hope for improvement in the future.

 

As for the stability of UL Speed, further analysis by engineers may be needed. Let's wait and see how Asmodeus83 communicates with the engineer and see what progress they make.

  @Joseph-TP still the same speed drop on upload with all ECO modes disabled.

If anything it even got worse.

 

I am 99% sure no-one at TP-Link has tested this device with a Samsung S24 ultra or S25 Ultra.

Please proof me wrong by providing a speedtest result showing 3.5 Gbps+ download and 3.5 Gbps+ upload.

 

Else, this is all useless to test.

I'm communicating with support and running tests to resolve this issue. I think it needs more time.

Hi @5Guru,

I understand your feelings, and we have tried to reproduce the problem you described and provide a suitable solution as soon as possible.

 

However, reproducing a problem is not as simple as using the same test equipment for comparison. Because each user's specific usage environment, network topology, network plan, and router configuration differ, all of which can be significant factors contributing to the anomaly.

 

If you are willing to continue troubleshooting with our engineers, I can escalate your case to an engineer.
