关于802.11r的测试，实现无ac无缝漫游

jwlili · 发表于 2017-5-31 22:35

已经试过了，唯一的问题，很多手机不支持。。。。

fryrice2000 · 发表于 2017-6-4 08:51

试过了，家里的APPLE设备支持效果还行，切换速度肯定比不上ac+ap那些
但是家用也差不多够了

老毛子的固件能用吗？

adavan 根本不支持吧

这个很强大给力

这东西的效果真的不错，2013年时被广告忽攸买了ubnt uap lr，效果惨不忍睹。同样的SSID最后一次在5AP下面测试，2条平行通道1侧3台1侧2台。用moto 860刷cm系统，通过android下面的wifi连接管理器，可以很好的看到手机自动切换到附近信号好的AP上。win8 pc上的realtek网卡使用windows自带的wifi管理软件则没这么聪明了，首先虽然是同一SSID，其实注意到每次连接到一个新AP上都输入了一次密码过程。然后就是根本不会自动切换，每次都傻傻的连接到上次连接成功的最后一次AP上，除非信号断了。最后没办法去下了个可以识别AP mac地址的第三方wifi连接管理软件，调试时自己才清楚连接到哪台AP上。
所以今天在win10系统上，主要是测试win10系统是否会主动连接到临近AP上。可惜家里密封性太差，两个AP信号都好于 -80dbm，不是能很好的观察到手机自动切换过程。
最后不管了直接在2实现了11R的AP上，主动踢除win10系统上的无线网卡，可以通过log很好的观察到无线网卡被踢皮球一样踢来踢去。然后通过windows共享拷贝大文件看有没有断开，首先由于sleep 5有点低，掉包的情况肯定发生，甚至注意到拷贝的进度条都发生不动的情况，但是最终还是成功把文件拷贝完毕，最关键是win10系统上的intel 7260无线网卡确实可以在2 AP上自动切换这就够了。面对一个AC 几千块，1套AC+AP几万块的现实问题。有时候并不需要什么传说中的无缝漫游，只要保证网络不中断可用就可以了，基于性价比考虑，11r的效果还是非常不错的。

while true;do iw dev wlan0 station dump|grep "7c:5c:f8:59:e8:f9"
if [ $? -eq 0 ];then
hostapd_cli disassociate 7c:5c:f8:59:e8:f9 interface wlan0
echo "`(date +"%m/%d/%Y %T")` disassociate successfully_" >> /tmp/log1;fi;
sleep 5;done

20170907今天测试了同样SSID非802.11r模式，结果win7下面的realtek,win10下面的intel无线网卡都可以在2个优酷路由宝刷了lede 17.01.2系统里自动切换，如果仅是通过拷贝windows共享的过程验证，似乎并不能说明什么。。。有点小失望。。。

可以，这个不是关键

楼主，我用一个K2和一个水星mw4530R刷了新的lede，安装了wpad。2个都有类似的问题：在快速漫游那里 r0kh和 r1kh 这2列表，只要一填写的数据，保存后，相应的wifi模块就启动不了了。折腾了无数次都是这样。郁闷死了。

闲杂人 · 发表于 2018-1-17 22:57

配置好路由了。发现iphone7 ios10.2.1版本居然不能漫游。而我家里人的2年前买的小米手机居然支持。晕死了。

楼主你的AP都是相同信道的吗？

lsydy · 发表于 2018-6-12 10:09

ssh连上，依次
opkg update
opkg remove wpad-mini
opkg install wpad
基础配置，配置LAN地址，关DHCP，开WIFI，设相同SSID/加密方式/密钥，设不同信道
