Model: Archer AX55  
Hardware Version: V6
Firmware Version: 1.21.123.2

Hello everyone,

Hoping to get some help with a really frustrating issue I'm facing. My kids are trying to play the latest Minecraft update, and I'm having trouble getting it to work smoothly on our home network.

The specific version is from here:

Ever since they started playing this version, our network performance for the game has been terrible. I'm hoping someone with more networking knowledge might have some ideas.

Issue Overview

We're experiencing severe lag and rubber-banding, but only with this specific Minecraft version. All other games and streaming services are working perfectly. My setup is an Archer AX55, which has been flawless until now. The issue seems to be directly related to how this new update communicates with the router.

Symptoms & What I've Tried

I've gone through all the usual troubleshooting steps, but nothing has resolved the problem.

  • Consistent High Ping: In-game latency jumps to over 300ms.

  • Packet Loss: Noticeable packet loss, causing blocks to reappear and actions to be delayed.

  • Device Isolation: The problem occurs on both the PC (wired connection) and tablets (Wi-Fi).

  • QoS Settings: I have enabled QoS and prioritized the gaming devices, but there is no improvement.

  • Router Reboot: A full reboot of the Archer router and the modem temporarily helps, but the issue returns after about 10 minutes of gameplay.

  • Firmware: Router firmware is up to date.

My Setup Details

To give a clearer picture of my current configuration:

  • Router Model: TP-Link Archer AX55

  • Firmware: Latest official release

  • Connection Type: Ethernet for main PC, Wi-Fi 6 for mobile devices

  • HomeShield: Basic security features are enabled, but no specific devices are blocked.

I'm starting to wonder if there's a specific setting or a port I need to forward for this version that's different from the standard Minecraft ports. Has anyone else experienced anything similar with new game updates on their TP-Link routers?

Any suggestions would be greatly appreciated. Thanks

Hello @OmgBibi ,

Welcome to our community.

 

Could you please provide the hardware and firmware versions of your router? 

 

Here are some troubleshooting steps that may help you:

  • It would be best for you to compare your network with others, such as a guest network or networks using different routers.
  • Please try using a public DNS (such as 8.8.8.8 or 1.1.1.1) to avoid ISP DNS latency.
  • Please perform a continuous ping test: ping <game server IP> -t (observe latency and packet loss rate).
  • Please check if the game requires specific ports to be open and consider setting up port forwarding for Minecraft.
  • Please ensure that no other devices on the network are consuming excessive bandwidth during gameplay.

 

Best Regards.

Hi there,

It sounds like the issue is specific to how Minecraft 1.21.123.2 handles network traffic with your Archer AX55. Since everything else works fine, it’s likely related to UDP packet handling rather than a general network problem. Here are a few things you can try:

  1. Port Forwarding: Minecraft uses TCP/UDP 19132–19133 for Bedrock. Even though the router usually handles this automatically, explicitly forwarding these ports to your PC/tablets can help.

  2. Disable SIP ALG / Packet Inspection: Some TP-Link routers have features like SIP ALG or deep packet inspection that can interfere with certain game traffic. Try disabling these in the router settings.

  3. Check Wi-Fi 6 Settings: Sometimes the latest Wi-Fi 6 configurations (OFDMA, MU-MIMO) can cause packet drops with certain apps. Try temporarily disabling advanced Wi-Fi features and see if performance improves.

  4. Use Wired When Possible: You mentioned PCs are wired, but tablets are Wi-Fi. Try testing the game on a single wired device with all other devices disconnected to isolate the problem.

  5. VPN Test: Some users have noticed Minecraft updates behave differently with certain ISPs or routers. Running a low-latency VPN can sometimes bypass router-level traffic issues and improve stability.

  6. Router Logs & Firmware: Keep an eye on the router logs while playing. Sometimes firmware updates contain fixes for high packet loss, so double-check TP-Link forums for any hotfixes or beta releases.

Finally, you might also check if Minecraft 1.21.123.2 itself has any reported networking bugs—sometimes new updates introduce UDP timing issues that only the developers can fix.

Hope one of these helps you get smoother gameplay!
