BE800 support 8-10 Gbps PPPoE throughput?
BE800 support 8-10 Gbps PPPoE throughput?
Dear Team,
I have an Archer BE800 (BE19000 Wi-Fi 7) connected to a 10G ONT in bridge mode with an 8 Gbps internet package from my ISP. The PPPoE session does not exceed 3.5 Gbps download/upload, despite:
- Using Cat7 cables with 10Gbps full duplex link on WAN/LAN ports
- CPU load on Archer only 16% during Speedtest (idle 10%)
- PPPoE connection clearly limiting performance
Questions:
- Does the BE800 support 8-10 Gbps PPPoE throughput?
- Is there a known limitation in the PPPoE software stack?
- Is beta firmware available with improved PPPoE performance?
Best,
Perisa

Hello @perisa ,
Thanks for getting back to me.
As you can see, even the PC(with 10G network card) is directly connected to the ONT, the speed is only 1.4Gbps.
We can reasonably suspect there is a speed limit on the ONT side. We suggest you first consult your ISP to check the LAN port speed on the ONT, or you can use other 10G clients/routers for comparative testing.

Thank you for the quick reply and suggestion.
This is quite challenging for the following reason. When I connect the ONT directly to my desktop PC, it negotiates a 10 Gbps link speed between the two devices.
However, as soon as I initiate the PPPoE session, I immediately see that the external connection is only to 1.4 Gbps.
This ONT has a confirmed 10G LAN port - for example, when I connect it to BE800 router's 10G port, they negotiate 10 Gbps between themselves.
Could you please advise on next steps? Perhaps checking PPPoE MTU settings or firmware optimizations for higher throughput?

Hi@perisa ,
Our testing department has not yet been able to reproduce your case.
Furthermore, your speed did not show a clear and significant change due to modifications to the Archer BE800. For example, firmware updates could cause a decrease in speed.
Even if the negotiation speed between the ONT and BE800 is full, we still need to confirm whether your PC (with a 10G network card) can handle the actual speed of 10 G.
Especially since you've already connected your PC directly to both the ONT and BE800, and the speeds are still unsatisfactory. Therefore, the speed limitation is likely caused by either the ONT or your PC (with NC).
You still need to pinpoint the cause, then we can determine if there are any feasible solutions to improve the speed.

@Joseph-TP I am currently using an Archer BE800 v1.0 router with firmware version 1.4.1 Build 20260119. I am experiencing a throughput limitation of approximately 3.5 Gbps during internet speed tests. Is there any firmware (official or beta) that improves PPPoE performance on this model? Are there any recommended settings to achieve higher throughput over PPPoE on a 10G connection?

Hello @perisa ,
The latest pre-release firmware version for the BE800 v1 is 1.4.1 Build 20260313; you can view it here.
However, regarding your specific question, I believe I have already addressed it previously, as follows:

@Joseph-TP Can you link me to the last production firmware version so I can upload it after these beta versions? Just to be sure that maybe the beta firmware didn't slow down the speed test, although I don't think so.

Hello @perisa ,
If you have not yet updated to the 1.4.1 pre-release firmware, the current latest version of the Official Firmware is:
Archer BE800(EU)_V1.20_1.3.5 Build 20251225 ,
Or Archer BE800(EU)_V1_1.3.3 Build 20251015
The latest pre-release firmware version for the BE800 v1 is 1.4.1 Build 20260313; you can view it here or install it via:
| Archer BE800_V1_1.4.1 Build 20260313 (Pre-Release Firmware) |
You may follow the guide to upgrade your router's firmware. How to Upgrade the Firmware on the TP-Link Wi-Fi Routers.
This version of the software can't be degraded to the previous official version.
