Model: Archer AX55 Pro  
Hardware Version: V1
Firmware Version: 1.4.3 Build 20250813 rel.63911(4555)

Hello,

First of all, i'm new. This is my experience with the product.

Digi Romania (bridge mode)/1 Gbps/OnePlus 12R.

 

PROS:
- Good coverage (3-room apartment, concrete walls, router located in the middle),
- 160 Mhz support (If you live in a block of flats or residential area i recommend 80 Mhz),
- DNS Privacy: DoT and DoH (I haven't tested),
- Small bufferbloat on 160 Mhz but less interference on 80 Mhz.

 

CONS/HIDDEN SETTINGS:
- ROAMING ASSISTANT (Signal strength hidden, i recommend -76 dbm maximum instead of -74 default),
- BEAMFORMING (Marketing or hidden, cannot be modified according to needs. Preferably: Explicit On and Universal Off),
- SHORT GI (Probably enabled and hidden),
- Tx Bursting (Probably enabled and hidden for Browsing only, cannot be modified according to needs. Affects online FPS games when ON),
- 1024-QAM (Probably enabled and hidden for Browsing only, cannot be modified according to needs. Affects online FPS games when ON),
- NAT BOOST (Surely enabled and hidden for Browsing only, cannot be modified according to needs. May affects online FPS games when ON),

- OFDMA loses between 100 and 150 mbps when ON (This setting should be available for 5 GHz only, not general. It is not even specified what type of OFDMA it is: DL Only, UL Only, DL+UL - like Asus routers).

 

BUG:
- Advanced - Internet - Advanced Settings: Primary DNS and Secondary DNS - cannot combine two different DNS. Always reads the first one. I use Asus AX59U with Openwrt, system detect both, but only uses the one with the lowest ping.

 

RECOMMENDATION:
- Advanced - Internet: Uncheck RX/TX Flow Control,
- Advanced - LAN: Uncheck RX/TX Flow Control,
- Advanced - IPTV/VLAN: IGMP Off completely (Snooping ON - if you have surveillance cameras),
- Advanced - DHCP Server: Lease Time 360 ​​minutes (6H) or 1440 minutes (24H),
- Advanced - Wireless Settings: OFDMA On (Test) or Off (if you have lag, desync, disconnections),
- Advanced - Wireless Settings: TWT Off,
- Advanced - Wireless Settings: Smart Connect Off,
- Advanced - Wireless Settings: Password WPA2-PSK(AES) on both 2.4 and 5 ghz,
- Advanced - Wireless Settings: WPS Off,
- Advanced - Wireless - Additional Settings: AP Isolation Off,
- Advanced - Wireless - Additional Settings: Airtime Fairness - On (divides the wifi transmission time equally) or Off (if you have lag, desync, disconnections).

I would have liked these setting to be separate for both bands, not general,
- Advanced - Wireless - Additional Settings: DTIM 1 (FPS online games) or 2 (Browsing/Netflix/Youtube),
- Advanced - Wireless - Additional Settings: Group Key Update Period 0 or 86400 (FPS online games/Streaming),
- Advanced - NAT Forwarding - UPnP: Off,
- Advanced - Security - ALG: IPSec On (if you use vpn from work) or Off all,
- Advanced - IPv6: Disabled (FPS online games), Enabled (Browsing/Netflix/Youtube),
- Advanced - EasyMesh: Off (If you don't have mesh at home),
- Advanced - System - Firmware Update: Off (If you have problems with the electrical network. You can also check manually from time to time),
- Advanced - System - Time:  time. cloudflare. com / time. google. com,
- Advanced - System - Reboot: Reboot Schedule: On/Every Day (I set 6:01),
- Advanced - System - Authorize Third-Party Services: Off
- Advanced - System - About: Off

 

5 Ghz/160Mhz values ​​- 700 Mbps (in another room), 750 Mbps (in the room with the router), 800 Mbps (near the router).

Compared to Orange Romania, Digi Romania loses between 100 and 150 Mbps due to the PPPoE connection.

Hello @Wlog_Ro ,

Regarding what you consider to be a 'Bug', please note:

 

This is actually expected and standard DNS behavior — it's not specific to TP-Link routers.
In standard DNS configuration, the Secondary DNS is a fallback only, meaning it is only used when the Primary DNS server is unreachable or fails to respond. Under normal conditions, the router will always send DNS queries to the Primary DNS first. This is how DNS works by design across virtually all consumer routers and operating systems.
The behavior you're seeing on your OpenWrt device (detecting both and choosing the one with the lowest ping) is a custom DNS resolution feature specific to OpenWrt's implementation (often handled by tools like dnsmasq with custom configurations). This is not standard DNS behavior and is not a built-in feature on most consumer routers, including the Archer AX55 Pro.
So to summarize:
• Your AX55 Pro is working correctly — it uses the Primary DNS and only falls back to the Secondary DNS if the Primary is unavailable.
• The OpenWrt ping-based selection is a non-standard, custom feature that consumer routers typically do not offer.
If you'd like to optimize DNS performance on your AX55 Pro, you could consider setting your Primary DNS to a fast, reliable server like 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google), which generally offer low-latency globally.
