Archer TX20E V1 – 1201 Mbps link speed but very low throughput and severe latency spikes
Hello,
I am experiencing severe and intermittent performance problems with my Archer TX20E V1.
Hardware:
- Adapter: TP-Link Archer TX20E AX1800 V1
- Wi-Fi chipset: Realtek RTL8852BE
- Driver: 6001.15.153.0
- PC: Medion Erazer Recon P20
- CPU: Intel Core i5-14400F
- RAM: 16 GB
Router:
- Movistar Wi-Fi 6 router
- 5 GHz
- Channel 116
The adapter reports:
- 802.11ax
- RX/TX link speed: 1201/1201 Mbps
- Signal: 88–89%
- RSSI: approximately -47 to -51 dBm
Despite the excellent reported Wi-Fi link, actual internet throughput can suddenly drop from 600–830 Mbps to approximately 50–110 Mbps without changing any settings.
There are also severe latency spikes. A direct ping to the router (192.168.1.1) averages around 30 ms, but can reach 75–170 ms. Discord has reached approximately 5000 ms during these events.
I performed an additional test using the same TX20E, PC and driver connected to a mobile hotspot. The adapter achieved 286.5 Mbps link speed, with 5 ms average ping, 26 ms maximum and 0% packet loss to the hotspot gateway.
This makes me suspect an interoperability/configuration/driver issue between the TX20E/RTL8852BE and the Movistar Wi-Fi 6 router rather than a simple signal-strength problem.
Could you please confirm:
- Whether there is a newer RTL8852BE driver than 6001.15.153.0 officially compatible with the TX20E V1.
- Whether there are any known compatibility issues with Wi-Fi 6 / 5 GHz channel 116 and the TX20E.
- Whether you recommend any specific TX20E advanced settings or router settings for this issue.
- Whether there is a newer beta/test driver you can provide for troubleshooting.
Thank you.
