而在标准的硬件方面,这款路由器也毫不吝啬,不但内置了支持ADSL, ADSL2, ADSL2+, and RE-ADSL的MODEM在内,并且还集成了一个标准WAN口,以备客户连接其它类型的宽带,比如光纤或网张接入的宽带,并且集成了一个肉置USB有线网卡接口,直接插在电脑上就可以上网了,不需要电脑有网卡.方便即插即用型电脑,也便于硬件工程调试。8 W, I; f9 P2 |! s
惟一让我感到奇怪的是,这个无线路由器的无线部分没有发现DHCP功能,并且和有线网络存在于不同的两个网段(有线网络有DHCP功能,默认网关地址是172.24.1.250,而无线段的网关地址是172.26.1.250),估计这个默认设置可能是出于安全考虑,即防止无线端有非法用户进入。由于这个无线路由器专业的功能太多,所以可能是应该在哪个菜单中设置一下才行(初步估计是需要设置NAPT功能,我不太懂:),不过通过指定无线网卡的IP地址上网是没有问题的!(即设置成和172.26.1.250为同一个网段)如果有哪位朋友买去后知道在什么地方设置无线自动DHCP的话,告诉大家共享一下,这样这个路由器就真的太完美了。
