Ieee802 . 11b can support high digital rate and provide good access service . the devices that support ieee82 . 11b is more and more prevalent . so we adopt it as our mac protocol . this paper is mainly to research how wr can provide access service and control the unauthenticated users to access the network . we choose the operation mode of the nic and use visual router and arp to resolve the problems 本文针对在链路层采用ieee802 . 11b协议以后,结合移动用户要在多个无线路由器间切换,研究了无线路由器提供接入需要解决的问题,通过接入网卡的设置,虚拟路由器、 arp代理和目的mac地址的处理等解决了对移动用户全网漫游的支持。
