Re: [PATCH 00/24] rtw89: add Realtek 802.11ax driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Previous result is from a single antenna PCI card of 8852AE.
After test on another Laptop with 8852AE, it works fine.
Result:
AP ASUS AX86u: TX 660M RX 880M

AP Netgear R7800: TX 500M RX 561M
Looks like the performance is affected by antenna.

The error log is not reproduced again.

Hi Ping-Ke,

After applied your patches on 5.17-rc7, tested on pci device:
04:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8852]

I found the performance is a bit poor on TX especially.
Tested on Intel AX210, it's result is TX 461Mb/s and RX 547Mb/s at the same position.
