  • openwrt 外挂usb 网卡 RTL8188CU 及添加 RT5572 kernel支持

    RT5572 原来叫 Ralink雷凌 现在被 MTK 收购了,淘宝上买的很便宜50块邮,2.4 5G 双频。在 win10 上插了试试,果然是支持 5G。这上面写着 飞荣 是什么牌子,有知道的和我说下。

    (win10 现在驱动真好方便,一更新就有了,也不需要什么驱动精灵之类的)

    自带的 linux 驱动在这里:https://www.mediatek.tw/products/broadbandWifi/rt5572?spm=2013.1.0.0.40b44978CqLJns  2018-11-27 今天看的时候,它把 mac 和 linux 的下载地址搞反了。

    先在 ubuntu 16 上进行测试。

    下载源码:(选 最右边 mac 那个,它放反了)

    DPO_RT5572_LinuxSTA_2.6.1.3_20121022.tar.bz2

    手上有一个 RTL8188CU 先用它试一下,linux 自带驱动了,配置一下插下就能识别出来。

     

    正常,2个 radio 。

    测试 RT5572

    树莓派3b+ 正常使用

    iwlist wlx441ca87f7a17 scan
    wlx441ca87f7a17 Failed to read scan data : Resource temporarily unavailable

    今天在 openwrt 的 配置项里面找了下,有个 rt2800 的打开这个就能识别到 RT网卡。 

    经过测试,虽然可以识别,却不能使用。

     

    在有时间,在研究吧,最近事多。
