IT数码及移动互联 【求助】关于笔记本电脑的无线上网问题

见过老杨的贴子说,要带网线和水晶头,在电脑城现买现做了2接头,一次成功,回家又做,也通了.嘿,到爱城谁要做接头找我!我把网钳带上.
又听说最好还要带上无线网卡,问:无线网卡选什么标准的才和加拿大的兼容,AP还要买否?
 
无线上网的标准是全球统一的。
如果只能无线网卡,没有AP,只能在图书馆等公用无线网点使用。如果想自己在家弄个无线网,就必须有个AP。
 
Wi-Fi is quickly gaining in popularity with access points across the United States increasing by approximately 100% in 2003. Wi-Fi refers to a set of wireless networking technologies more specifically referred to as 802.11a 802.11b and 802.11g. These standards are universally in use around the globe, and allow users that have a Wi-Fi capable device, like a laptop or PDA, to connect anywhere there is a Wi-Fi access point that is available. The three standards that are referred to signify the speed of the connection they are capable of producing. 802.11b (which transmits at 11 Megabits per Second) is the most common, although it is quickly getting replaced by the faster Wi-Fi standards. Both 802.11a and 802.11g are capable of 54 MBPS, with 802.11a adding additional capabilities. Across the board, all of these Wi-Fi standards are fast enough to generally allow a broadband connection. Wi-Fi is an emerging technology that will likely be as common as electrical outlets and phone lines within a few years. Wi-Fi adds tremendous levels of convenience and increased productivity for workers whose offices are equipped with Wi-Fi, as well as travelers that can increasingly access Wi-Fi in airports, coffee shops, and hotels around the world.
 
加拿大是802.11b标准。因为802.11g兼容802.11b。所以我在国内带来的是802.11g/108M的。其实54M已经足矣(国内¥100左右,108M需200多)。Router这里很多二手的便宜。
加拿大很多地方都不加密(有些老外可能不知道怎样加密),只要有无线网卡,就可以收到,有时可收到很多。
