Model: Archer AX6000  
Hardware Version: V1
Firmware Version: 1.4.2 Build 20250603 rel.65464(5553)

Hi,


For anyone that may have tried out the feature on this router, I'm curious to learn if there was a noticeable performance improvement.

 

Looking to improve the overall network performance specifically for NAS that is primarily used for file transfers, backups, etc.

 

Currently using a 2-port static LAG (no LACP) via smart switch but the performance improvement isn't meeting my expectations.
NAS is configured for Round-Robin mode - for fault tolerance and load balancing.

 

Tried configuring LACP capable switch then NAS in 802.3ad dynamic link aggregation mode, but NAS crashed and burned. Hung up then lost? it's network configuration upon reboot so I backed off.

 

I know that I can and should test this but thought it would not hurt to ask the community.

 

Thank you

Hi @Genarro_6k ,

Welcome to our community.

 

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

ISP modem—router )))((( client devices

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

 

Please check if you set the Link Aggregation correctly: How to configure link aggregation on TP-Link Wi-Fi products 

 

Have you updated the firmware recently?  Did this issue start with a firmware update?

Hi   @Joseph-TP,

 

Yes, that is my network topology.

 

The (static - not LACP) LAG is currently configured via a smart switch. Since speeds are not meeting my expectations, thought I would explore the possibility of implementing LAG on the router. However, support.usa@tp-link.com shared the following:

 

 

 LAG Configuration – Switch vs Router
 
Since the AX6000 only supports LAN Link Aggregation on LAN Ports 1 and 2, it can technically form a LAG (802.3ad LACP) to a compatible NAS or managed switch. However:
 
If your NAS struggles with LACP (as you described), then using a static LAG on your switch (with the NAS connected directly to it) is usually the better approach.
 
The router doesn't manage Layer 2 traffic as efficiently as a dedicated switch, so creating the LAG on the switch side helps performance and reduces bottlenecks, especially for intra-LAN data like NAS streaming or backups.
 
 
(Actually my AX6000v1 supports LAN Link Aggregation on LAN Ports 2 and 3.)
 
Firmware was updated recently but slower than expected and advertised speeds of NAS vendor are not related. I've opened a ticket w/NAS support.
 
Thank you for your response Joseph, I appreciate IT.
 
 
Kind regards

Hello@Genarro_6k ,

Thank you for getting back to me.

 

May I know where you saw the statement 'AX6000 only supports LAN Link Aggregation on LAN Ports 1 and 2'?surprise

 

From page 68 of Archer AX6000(US)_V1_User Guide, it says 'Toggle on Link Aggregation to enable it and reboot the router to apply the settings. The LAN2 and LAN3 ports will be used for Link Aggregation.'

I am well aware of that.
