@Kevin_Z Hi Kevin,
i don't think any of us with the newer versions of the firmware with the reboot and wifi drops want to go back to the old versions.

is there a newer version of the firmware that has both 2.5gbps fix as well as keep stability of the router and wifi?

if you want to get it running on 1.1.6 beta this config has worked for me


from telnet run

 

ip link set eth1 down

ssdk_sh port interfacemode set 6 sgmii_plus

ssdk_sh port interfacemode apply 6

ethtool -s eth1 speed 2500 duplex full autoneg off

ip link set eth1 up

 Is there an update on this? 

I am discussing with AIS my ISP on using a GPON directly into the BE800 instead of running through a Huawei router that they use as their home fiber termination. 

They are open to working with me on it but i cant find any reference on which fibre GPONs if any are known to work work with the BE800.   Does TPlink support an inhouse  SFP+ GPON ?

Is GPON reliable on the BE800?
 

General comment.

I have two BE800's with a 10 Gbs wired backhaul in a Main - AP configuration. I tried mesh and it didnt work well for me because i need configuration options on the AP node that i cant do in the Mesh and the Mesh was flakey. The AP BE800 is  wired because at more than 3 metres the WiFi back haul was down to less than 1Gbs.    

I've now wired in my desktop PC into the AP because even though  with Win11 24H2  (at less than 1 Metre) I can now see  a  consistent 5764/5764 Gbs WiFi 7 connection into the BE800, it file transfers consistently   at only 2/3 of the Wired 2500Gbs connection.  For general use around the apartment WiFi 6 is faster than WiFi 6E on my Samsung phone  unless I sit on top of the Router.

Everything on the BE800 seems to have a maybe in the future solution in beta firmware. It would be quite nice in a premium  12 month old product to see some fully supported release quality features and stability.   It was hinted in this forum that a new production release of firmware would come mid January  2025 - we're now first week of February.  I have a nagging fear everying will get fixed in V2 hardware which seems to be standard practise in the Router business, meaning V1 will  get abandoned.

My ISP AIS Thailand wont support a BE800 with a PON at the current time. My contract has 10 months to run so i'll look at the alternative ISPs in Thailand and think about swapping then.  It would be nice if TP-link in Thailand would talk to the ISPs. The only WiFi 7 solution currently generally available  in Thailand is TP-Link. The ISP bundled high end  offer is a TP Link BE85 set  which has an SFP port. Yet they wire the Fibre through a cheap Huawei Router !  

---------------------------------------------------

Firmware in both BE800 is  1.1.99 Build 20241126 rel.18304(4153)

I was using that because i read it might solve WiFi mesh problems.

Summary config now is:-

ISP Fibre----1Gb/500Gb----HG8245H------1GbE------BE800 Main--------10GbE----------BE800AP

I live in a 60 square meter rented apartment. The 1Gbs fibre connection is in the living room with BE800 Main wired through a HG8245H

BE800 Main  has a wired TV, wired Android streaming box (Both 1GbE),  and via WiFi a second TV in the main bedroom (WiFi5),  Pico 4U VR head set  (WiFi 7), two Samsung S24U phones (WiFi 6E) a Dell WiFi 6 /2.5 GbE  laptop  and a few WiFi 2.4  IOT devices .

The BE800 AP is in the spare bedroom office. It has a wired desktop (2.5Gbe,BE200 WiFi7  I914th gen,  4900 ) , wired Qnap NAS (2x 1G LACP)  and a printer  (2.4 Wifi).

Originally I had set to WiFi backhaul. The two BE800 are only about 4M apart but with a modern condo wall between. The drop off on WiFi 7 and even 6E is dramatic and killed the VR headset streaming from the Desktop.

So i drilled through the wall and switched to a 10G wired back haul.  Wired Port to Port between the main BE800 and BE800 AP  I can get a full 2.36Gbs. Im still better to have both the Samsungs set to WiFi 6 not 6E to get fast coverage across the apartment.

The observed copy problem is on the QNAP  Nas -- BE800(AP) -- Desktop  PC

I get fairly consistent 226 Mbs copy speed  wired. It fluctuates between 50Mbs and 200Mbs on Wifi 7 with the WiFi Antenna 1M from the BE800. It looks as though its buffering or flow controlling somewhere. That might be a combination of WiFi 7 and LACP on the BE800.    I'll try and run some tests  with the wired Dell laptop replacing the Qnap.
