Deco Mesh with Archer BE800 giving me headaches (Archer AX75 works like a dream)

Model: Archer BE800

Hardware Version: V1

Firmware Version: Archer BE800(SG)_V1_1.0.12 Build 20231117

I have been running a home network seamlessly using the Archer AX75 as a router and Deco BE85 and other deco models for the mesh. The Archer is in router mode with wifi disabled and decos are in Access Point mode for great wifi coverage.

I am about to move from 1 Gb to 10Gb internet at home, so I bought an Archer BE800 router, which can manage 10Gb, in advance to replace my Archer AX75. It has been a disaster!

The Deco network keeps failing, and the internet keeps falling. I sometimes get speeds of 500Mbs; other times, I get 10Mbs. Worse, the Deco mesh keeps dropping signal.

To make sure it wasn't any other issue, I swapped it back to the AX75, and everything is working perfectly giving me wireless speeds of 700-900Mbs (I am still on the 1Gb service) depending on where I am at home.

I then swapped back to the BE800, and everything went crazy, and nothing worked well.

Anyone else having this issues? Any fixes?

Why will the Deco work well with the Archer AX75 and not the Archer BE800??

I have issues on the BE800 itself. Even when I plug my laptop via ethernet directly to the back of the BE800. Keeps dropping internet. Works for a few minutes and then dies.

I did a factory reset, updated firmware and started all over again.

Here is the negotiated speed:

Here is the speedtest via ethernet to the BE800:

@dis69

I thought that you were on the latest FW release already. Which FW version you're using now.

I can't see the negotiated speed screenshot - is everything OK there ?

Do you have any internet drops now ?

Firmware:

But still havoc if I unplug ethernet and use the Deco Mesh. Something is not right.

Tried multiple things but each time I go back to the AX75.

Dropped while typing this msg (laptop connected via ethernet to the BE800 so not even wifi) and now switched to my mobile wifi to finish the post. Something not stable with the BE800.

@terziyski

Here is the negotiated speed:

EasyMesh is OFF.

Problem is not only on Deco. Internet drops when I connect via ethernet to the BE800 and also when I connect directly to the BE800's wifi.

All settings otherwise identical to the AX75 as far as I can see.

Problem with hardware or firmware?

@dis69

It's hard to say at this moment because the root cause was not identified yet, but I would bet on FW.

10G ports seem fine - what hardware do you have connected at BE800 LAN ports 1 and 4 ?

@dis69

Nothing abnormal in the connections. Probably @Sunshine will come up with a way to troubleshoot your issue.

I just noticed that there's a new FW release for US region marked as version 1.1.1 Build 20240227 rel.33191(5553).

It's quite possible that a new FW release will follow for SG FW region as well.

Hi, let me confirm the following information before escalating your case to our senior engineer:

1. When using BE800 only(all Deco units disconnected), speed is normal, but internet drops every a few minutes, will it recover automatically or you have to restart the BE800? do you see exclamation mark on the LED screen when internet drops?

2. When using BE800 with Deco network, internet still drops on BE800, which causes Deco network losing internet frequently, BE800 wired and wireless speed is normal 900+Mbps but Deco network speed is only 500Mbps and sometimes 10Mbps, am I right?

For the BE800 internet dropping issue, if possible, please check if there is still WAN IP address or not when the issue happens, if so, try to configure Internet DNS servers manually to 8.8.8.8 and 8.8.4.4 on Advanced > Network > Internet > Advanced Settings to see if it helps.

By the way, who is your ISP please? please share with us a complete network topology as well.
