使用wifi camara的麻烦

webowl

sunny兄，谢谢，不知道为什么我在uverse之下接router，无线设备就是找不到这个router。
deng兄，也许是我的话描述不清楚，靠，兄弟现在英语没学好，中文到退步不少
大概就是uverse 一体router, 无线设备太多了，有些设备容易掉线或连不上。想加个router桥接或二级路由，但是老是搞不定，桥接uverse的router没有桥接设置，加二级路由后wifi设备找不到加的路由。
网上看了，只能把uverse的路由disable掉只用modem。
anyway，谢谢各位回复，具体还得自己搞定。FJC兄，好像ATT router只是限制了无线客户的数量。闪了吧。各位。我再试试看吧。

I think I understand now.
There are two solutions.

1. Set your model/router in passthrough mode. I worked with several ATT model/router, this can all be done.
Then hook up your own wireless router to the ATT wired LAN port. This router will get a public IP on the WAN and you can set your own NAT DHCP on your LAN. For example the public WAN IP is 62.23.12.101, your LAN IP is 192.168.2.x.

2. Even if you can't change your router to passthrough mode. You can still daisy chain your router to the ATT modem/router LAN port.
Let's say your ATT publicn IP address is 62.23.12.101, your ATT LAN IP is 192.168.1.x.  You hook up your own wireless router WAN port to the LAN of ATT modem/router, and the WAN IP of your own wireless router is 192.168.1.2, you can NAT and DHCP on your own router LAN address such as 192.168.2.x.
The second way, if you need view your camera from your phone on 3/4G, you have to port forward twice. It is more complicated, but still easy to do if you know what you are doing.
For example, you browse to 62.23.12.101:80, you need forward port 80 on ATT model/router to 192.168.1.2, and on your own router, you need further forward port 80 to inside subnet such as 192.168.2.10 if 10 is your first camera. on the ATT modem/router, you can DMZ to your own router's WAN IP. This will make work a little easier.

Hope you understand this.

ATT modem/router has all their password printed on the model, so you have full access, this is very nice for IT guy.

顺便说一句，我刚才说的解决方案是assume你的问题成立。
很可能你的问题根本不成立。
我很难相信ATT　router　DHCP只给１１个IP。
如果真是这样，你可以自己改DHCP　range，　给自己１００个好了。

这个11个channel是对北美2.4G来说。5G channel多很多。另外如果上了11n或ac，可用channel就要少，因为channel bonding。
anyway，就2.4g来说，11个channel里可用channel只有3个（最多四个）。为什么？因为不能overlapping。具体见这里：
http://en.wikipedia.org/wiki/List_of_WLAN_channels

在具体到router，同一时间只会工作在一个channel上。除非是个highend router，带多芯片同时支持多对antenna。

楼主这个问题是由于设备过多，而且设备和router距离相差太大。wifi其实是单工的。一个设备xmit，其他所有设备全部都shutup。如果这台设备距离router很远，那幕速率就会低。会多低？最低到1m。而且可能会有很多重传。造成整个网络performance下降。另外wifi多broadcast和multicat很不友好。所以尽量不用bc/mc。

这个解决方案嘛，如果router支持，把高速设备放到5g，低速放到2.4g试试吧。

用自己的router连到AT&T的modem上，自己的router，爱挂多少设备就挂多少设备，前提是你AT&T U-verse的总带宽够用。
