Enhance the Overall 5G network stability for Deco X50-5G/Archer NX200/NX500/NX600
Hi, is the current firmware 1.7.0 3.0.0 v60a2.0 Build 250904 Rel.72968n?
May I know your mobile ISP?
"when switched to 5G (5G NR), it starts dropping packets and experiencing ping times of up to a second at times."
-When it happened, would there be any change to the internet light on the Archer NX200?
-How about the internet status here:
Best regards.
i have an archer nx200 v2.0 with firmware version: 1.0.0 3.0.0 v60e0.0 Build 240822 Rel.76438n
i got a notification to upgrade to 1.2.0 3.0.0 v60e0.0 Build 250725 Rel.73467n
Is there a specific reason i should upgrade?
ChatGPT mentions issues after updating: 
1) Connection Instability / Drops
Several users on the official TP-Link community forums are reporting that after updating to the 1.2.0 firmware, their Archer NX200 stopped working reliably — the internet connection drops frequently, and the router’s admin status page shows messages like “Please configure DNS manually.”
2) Need for Manual Band Fixes
One user said that after the update, the connection became unstable with automatic band selection enabled. They resolved it (partially) by manually fixing the 4G/5G bands — but still noticed minor stability issues they didn’t have before.
3) Intermittent Internet and Slow Web UI
Another forum report from a different user also describes intermittent internet even after the firmware upgrade, and slower than expected access to the router’s management page — despite being wired directly to the device.
i know it may be wrong, however it gave me second thoughts... i mean it works fine as it is...
Moreover i cant find the release notes anywhere....
thank you in advance
Hi, thank you very much for the update.
Can you consistently reproduce this issue on this laptop, dropping packets and experiencing ping times of up to a second at times?
-If yes, can I have the model number of this laptop? Is it connected to Archer NX200 via an Ethernet cable or by WiFi?
The ping test isn't as bad as it sounds, and if it can't be reproduced in a short time, further troubleshooting wouldn't be easy.
Thanks a lot.
Best regards.
Hi, thanks for your time and patience.
So, using a laptop to ping the WAN IP address from the internet, then. Can you consistently reproduce this issue when Archer NX200 is on the 5G network type, as the ping test in the screenshot doesn't look very bad:
By the way, how about the clients connected to Archer NX200? Were they running into any issues when NX200 is on the 5G network, such as slow loading during web page surfing/video streaming?
Wait for your reply.
Best regards.
