Netia S.A. Polish ISP.
Firmware Version:
1.1.1 Build 20240227 rel.33191(4555)
Hardware Version:
Archer BE800 v1.0
Yesterday I did a Factory reset and that seemed to fix it, my only worry is that it may happen again and I would need to keep resetting it. Not sure what was the problem before that.

@benoitm974 Are you experiencing the same issue that the BE800 SFP+ port can only work at 1Gbps?
Could you please tell us the specific model of the switch or ONT that the BE800 is connected to?

@Kevin_Z I own BE800 HW 1.0 (DE), I'm using GPON Huawei MA5671A SFP to connect to French ISP Bouygues. the SFP was tested with a media converter and works in 2.5Gb directly, yet on BE800 SFP port it start at 1Gbps. BUT once the BE800 is booted If I remove/re-insert the SFP module it switch to 2.5Gbps and performance are good, it is stable for at least 48h (not tested longer so far). I've tried with both debug and production firmware i get the same behavior.
Also using the debug firmware, after boot if i connect via telnet and just do a 'ifconfig eth1 down', then 'ifconfig eth1 up' then it switch to 2.5Gbps too.
I tried to change the option "Internet Port Negotiation Speed Setting:" from auto to 2500 and reboot -> no difference found...
So far I tested firmware
BE800_V1_1.1.6_240808
BE800v1_1.1.6_240711_beta
BE800v1_1.1.1_240322_beta
BE800v1_1.99.97(1.1.1)_240417_userdebug

Thank you so much for the detailed description of the speed issue you're experiencing.
BE800 now has received a new official firmware, and you may check for updates on your router web or via the Tether App. Or you may check this thread first to find out what has been modified in this version:
Archer BE800 New Software Enhances System Stability and Optimizes MLO Network Stability
BTW, did you get the beta or debug software from our support engineers? If that's the case, I would suggest discussing it with them directly via email if there is still an issue after installing the latest official firmware on the device. I believe they will be happy to assist further.

Been using the latest Archer BE800_V1/V1.6_1.1.6_Build 240808 (Official Version) for 48h same issue cold start the SFP is 1Gps... You need to unplug and replug it for it to switch to 2.5Gps... very annoying.
I'm not in contact with engineering for the beta version but would love to help or test alternative beta for fixing this issue... in this state not getting 2.5Gbps at boot is a reason for me to return the product to amazon since i only bought it for using my 2Gb fiber line...
