TI中文支持网大家好，我在用evm sk的板子的时候，遇到一个问题，就是wl12xx这个wifi的速度上不去，麻烦大家帮忙看一下是什么问题
用的是官方的镜像，uboot是我自己编译的(官方的源代码，未改动)，linux内核是4.1.18
Linux am335x-evm 4.1.18-gbbe8cfc #1 PREEMPT Tue Apr 5 19:44:01 EDT 2016 armv7l GNU/Linux
wl12xx的固件版本如下
[ 253.274814] wlcore: firmware booted (Rev 6.3.10.0.141)
信号强度：
Connected to 78:a3:51:2b:f0:d8 (on wlan0)
SSID: LEDE
freq: 2452
RX: 402840 bytes (4287 packets)
TX: 10033219 bytes (6762 packets)
signal: -60 dBm
tx bitrate: 24.0 MBit/s
bss flags: short-preamble short-slot-time
dtim period: 1
beacon int: 100
iperf测试带宽的时候，断断续续，就算有信号，也不超过10mbps

Jian Zhou：
目前更多的是用WL18xx系列了，你可以去无线论坛资讯下。

回复 Jian Zhou:
好的，谢谢。
主要是我们用３３５８接上sdio到４.1.13之后的内核速度就上不去，所以想做一个对比。
