Model: Archer BE9300  
Hardware Version: V2
Firmware Version: 1.2.1 Build 20250723 rel.35080(4555)

Hi, as the titel says I am experiencing a high amount of packet loss on my internet connection since using the BE9300.

I did not have this issue before when I only used the modem/router provided by my ISP.

Supposed solutions offered on other threads and online have not resolved this issue, i have tried:
- Manually configuring the channel and bandwith for 2.4ghz/5ghz and 6ghz

- Enabling and disabling the MLO network (SSID was the same as the SSID for my 2.4ghz/5ghz and 6ghz SSIDs)

- Trying different SSIDs for 2.4/5 and 6 (MLO disabled), the issue still persisted on all bands

- Changing the DNS to 8.8.8.8 and 1.1.1.1

- Connecting the BE9300 directly to my fiber outlet box and using the ISP modem as bridge in between

- QoS, Guest and IoT networks, IPv6 and EasyMesh are disabled

- Firmware is up to date

- The router is placed in an optimal location, I have also tried using different cables

 

Is there maybe anything I haven't tried yet? Otherwise I will sadly have to return this product as this is not workable for me.

 

To double-check I ran a pingplotter to google.com using the BE9300 both wired and wireless, and using my ISP modem connected via ethernet.

Hi  @Joseph-TP, 

Coincidentally after switching back to the BE550 from my ISP modem after testing, I miraculously haven't had any more packetloss issues.
I did change the transmit power of the 2.4ghz/5ghz band to "Middle" instead of "High", but that doesn't explain why my packetloss on my devices connected via ethernet has also disappeared. Maybe it restarting the BE550 for the nth time eventually resolved it.

 

Here is the information you requested, maybe it will be usefull for a future case:
I first had the following topology, which gave network issues:
fiber optic outlet box — ISP modem(bridge mode) — BE550 — / )))((( client devices

 

After that i tried it without the ISP modem, which at first gave the same issues, until switching the BE550 out for the ISP Modem and back for testing:

fiber optic outlet box — BE550 — / )))((( client devices

 

Both configurations were tried with different cables/wall-outlets, multiple power-cycles of all devices and multiple factory resets of the BE550, I even tried an other modem from my ISP (same model). There is a switch between the fiber optic outlet box/BE550, however I did not change anything with the switch causing my network to have issues or solve the issue.

 

Because of IPTV restrictions my ISP doesnt allow putting the modem into an official bridge mode, but it does allow the use of third party routers connected to the modem.

In the current topology, I don't think im able to use IPTV, because of the way TP-Link configures IPTV settings. However I only get internet from my ISP, no IPTV, so this is not an issue for me.
My ISP is KPN in the Netherlands, they currently use/sent an "Experia Box V12" as modem.

Hello  @MartijnT ,

Welcome to our community.

 

Have you tried contacting local support for a faster response?

Who is your ISP?  May I know if your network topology diagram is as follows:

fiber optic outlet box — ISP modem(bridge mode) — BE550 )))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

Ensure that all routing functions (such as DHCP, firewall, UPnP) are completely disabled on the ISP device in bridged mode.

Is there a switch between the router and modem? If so, please try removing it.

 

In addition, please perform a hard reset on the router and then reconfigure it. For the sake of insurance, it's always recommended to save a copy of the router's Backup Config file before upgrading or downgrading.

Hello @MartijnT ,

 

You mentioned that everything returned to normal after modifying the transmit power. I think this is a very important factor.

Of course, please continue to monitor the network's operation, and please don't hesitate to contact us with any updates.
