用ROS,做无线路由器,最便宜的无线网卡是哪款

你运气好，碰上我这个ROS达人了~~~

这个我研究1年了~~~ROS做无线最好的选择是 ATHEROS AR5414A，要绿版的不要篮版的~~~

附我搜集的资料：

     ATHEROS AR5414A芯片台机一体无线网卡 ROS 软路由推荐使用

     附送4DBI增益天线。RouterOS 完美支持 5G 最高108M 连接，是做无线软路由不二的选择，让你的投资不会落伍。

找遍百度有比我提供这么准确无误的答案吗？这都不采纳从此不再来百度~~~

楼下的你根据我的关键字顺藤摸瓜搜到的资料吧~~~你这份文档我也有~~~

我想提醒帖主的是，笔记本+ROS蹭网的创意是美好的，但是不切实际啊~~~

记住有位ROS达人是这么总结玩ROS的经验：

“说实话，玩DD-WRT不如玩ROS，玩X86-ROS不如玩RouterBOARD-ROS，我就是这么一路走过来的！现在入门级的RouterBOARD板都价廉物美了，相信玩Wi-Fi/DD-WRT/蹭网的人都会对RouteBOARD-ROS有兴趣的....玩DD-WRT和玩ROS的学习曲线相差不大的，可是ROS终究是一种企业路由技术，DD-WRT不过是一种家用娱乐技术......“

下面这篇文档,摘自ROS官网,你可以自己去看看,列出了ROS3.0版本所支持的所有网卡型号

就我目前所知,最便宜的是 Dlink DWL-G650 ,大约35 元,当然功率不是很大,如果做无线路由,只能一个房间内的机器可以连接,几乎无穿透性,

不过注意一点,这个网卡,是笔记本CardBus插槽,也称PCMCIA接口或者PC口,如果你的机器是Express口,是不能用的

其实你用ROS,笔记本电脑,最好是选USB接口的网卡,你可以对着下面的型号在淘宝依次搜索看看价格,授之于鱼不如授之与渔,哈哈.

至于楼上那位推荐 ATHEROS AR5414A 的,你就太搞笑了,没看你上面,楼主在和别人的讨论记录吗,都说了是笔记本电脑了,你居然推荐台式机PCI接口的网卡,实在搞笑.逗死了

另外还支持SR9 ，能够在900M 非视距的模式下，达到54M 的连接速度，不过这个卡太贵了。下面是他的资料
This mini-PCI card from Ubuquiti Networks features up to 700mW of output power as well as 54Mbps data rates and -93dBm of receive sensitivity performance. It also features advanced noise immunity functionality. The Super Range9 mini-PCI radio offers a great solution for Non Line of Sight (NLOS) communications. The radio is complimented with FCC Part 15.247 Modular Approval and an advanced software feature set courtesy of Atheros 802.11 MAC/BB technology. As a result this is one of the most powerful and full featured 900MHz wireless solution you can get.

For improved range and increased user capacity, the SuperRange9 is also capable of supporting 5MHz, 10Mhz and 20MHz transmission bandwidth in the 900-928MHz unlicensed band.

根本无需用ROS做无线,
只把ROS当路由,然后买一款较好的无线路由当交换机用即可
无线路由当交换机使用的方法,就是把无线路由的网关改成ROS同段IP中的一个,别和ROS冲突,然后关掉无线路由的DHCP功能,把ROS出来的内网插到无线路由的LAN口上即可.

我们的情况类似，不过一般无线网卡的功率都不是很大，而且原装pci的卡都很贵。我采用的办法是在taobao上买了一个minipci转pci的卡，然后买了个Atheros的minipci的卡，是一家买的，一共是100多。然后插在了routeros上，另外转接卡都支持天线，又换了个10db的全向。总体用下来感觉效果不错。一般routeros和bt3都支持Atheros的无线网卡，你根据taobao上搜索出来的结果查查支持列表，然后选择吧。

建议楼主买个无线路由器改成桥接模式，ip同网段，可以达到楼主想要的要求
