.....这位兄弟真会开玩笑。。。现在正常的笔记本有哪个不支持5ghz的802.11n?

无线的主要问题不是throughput,而是latency,这是无线stack决定的,overhead比有线多的多。所以网线在未来20年内是不会消失的。特别是一些对latency要求高的地方你是见不到无线的,...
你还真不懂, 普通wifi是2.4G频段, 5G是5g频段,
还所有wifi支持? 你都没听说过双频段吧

802.11n可以在5ghz和2.4ghz使用,双频道叫channel bonding, 不建议在2.4ghz使用,否则你的邻居会骂死你的。

不是802.11n就一定是双频道哦,没有channel bonding是单频道,撑死150mbps.

另外你现在买的机器802.11n还有不支持5ghz频道的?!4,5年前买的倒有可能。

支持双频段的router只有linksys 3500以上,其他都是2.4g, apple 的东西大部分支持,
你认为wifi都支持5g? 看看技术指标吧。

我正用着。linksys wrt610n. linksys 600n也是5ghz的,e3000也是。

我说的是网卡,现在还有不支持5ghz的网卡么?

你说的是双频道是dual band吧?用英文语义可以准一点。否则人家以为是channel bonding呢。。。。

有802.11n不代表是5g, wrt610不是双工双波段,只能有1个波段工作,3500以上才是双工,

。。。。。。你到底用过1545和wrt610n么?????我的dd-wrt显示的清清楚楚, wl1, 5ghz, 802.11a/n , wl0, 2.4G 802.11b/g/n.

1545显示5ghz,连频道都给我显示了,56+54....2.4G是没有56和54频道的。channel bonding的还是!!

ETA: 看来你玩router还不是很熟,现在谁买了router还用oem firmware的,linksys自己写的firmware有几个像样的?所有人早换dd-wrt了,802.11a/b/g/n 5ghz双通道都支持, vpn, astrisk, usb printer server全支持。

Linksys3500是双波段,全双工,我正考虑买,
wrt16应该是很老的了,不知道是否双工,
很多router都没有5g频段。

dd-wrt很好,不但功能丰富,还能调节发射功率,如果调到100mw,2个房子外都能收到。 不过貌似在北美个人使用2.4Ghz和5Ghz的功率超过28mW是违法的。。。。呵呵。。俺就当一回罪犯啦。
