My thoughts...

whynot108(小累神)
Scenario 1

ISP<------->cable modem<---(ethernet)--->wireless router<---(802.1g)--->wireless bridge<---(ethernet)--->home switch<---(ethernet)--->PCs

PCs get IP address and default gateway address from the wireless router (DHCP server enabled on its wireless interface).

if your home router only has 4 switch ports and all ports are occupied, you need to replace the router with a switch, 1 Uplink+ 4 10/100 ports.

Scenario 2

ISP<------->cable modem<---(ethernet)--->wireless router<---(802.1g)--->wireless bridge<---(ethernet)--->home router<---(ethernet)--->PCs

PCs get IP address and default gateway address from the home router (DHCP server enabled on its LAN interface).

The WAN interface of the home router gets IP address and default gateway address from the wireless router (DHCP server enabled on its wireless interface).


I did not test my thoughts. Hope it will be helpful. :)

  • 工作学习 / 专业技术讨论 / 有线局域网上的所有电脑，如何通过附近的无线路由器上网？ -jimpoo(James); 2005-11-7 {683} (#2594128@0)
    由于cable不能连接到2楼，我的cable modem 连接无线路由器（带4个RJ45口）后，只能放在basement。而1楼、2楼的电脑都要安装无线网卡才能做无线上网。
    我的问题是，现在有4台电脑已经通过一个有线路由器连接成一个小局域网，我不想为每台电脑都安装无线网卡，能否添加一个什么设备让整个局域网上的电脑都可以实现无线上网？
    1、 使用D-Link DWL-G820 Wireless Ethernet Bridge ，并且连接到局域网的router WAN口，是否可行？
    2、使用D-Link DWL-G800AP Wireless Range Extender，是否可行？
    3、使用Linksys WAP54G，是否可行？

    一般的wireless router都是连接cable modem/dsl modem， 然后发射信号。既然这样，有没有可能2个一样的wireless router能够相互通信，让每一个wireless router所在的网络都能够存取internet?

    谢谢！
    • 不用讨论了,直接交咨询费,就帮你搞定了. -imonst(1B1FP); 2005-11-7 (#2594284@0)
    • 感觉1可行。 -akoei(停车**枫林晚); 2005-11-7 (#2594715@0)
    • 问题不在于你怎么选, 而是你怎么安排带宽. 既然你的modem只能在basement, 那不管你楼上怎么连接, 需要一个wireless连接必须是54M的, 其他的则好办, 或者分流. -siptoronto(Flash_Flex); 2005-11-8 (#2596008@0)
    • 谢谢各位的意见，不过，都没有回答我的问题:-) ， 我认为问题不在于带宽，而是在于方案，只要选定了方案，再选择相关产品就解决了。 -jimpoo(James); 2005-11-8 {247} (#2596032@0)
      我有些迷惑的是，2个相同类型的无线路由器之间，能否做无线通信？当然，这2个或者多个无线路由器之间用cable连接是可行的，但我不希望用cable连接。如果2个相同类型的无线路由器之间能够无线通信，那么，是否跟某些产品牌子、系列有关？各位能否提供一下意见？谢谢！
      • 最简单省钱的方法，看看你家的电话接口是否接受RJ45头，若是，一般走的是5类线，把楼上的一个接局域网楼下对应的接猫。 -keepbugging(独行的猫); 2005-11-8 (#2596498@0)
      • It is very easy. Use a wireless router + a wireless bridge/access point. DLINK has all these stuffs. -c_sea(雪山飞狐-悠然眺蓝山); 2005-11-8 (#2597112@0)

      • I think plan 1 should solve your problem. A wireless birdge is much cheaper than 4 wireless card. But of course you only get 54M/4 . which is a bit slow -javaelk(果丹皮); 2005-11-9 (#2599807@0)
    • easy and doable. ISP—Cable Modem— Wireless Router@Basement <-----(wirelessly)---->Wireless Bridge@2nd floor <----(wired)----->Your PCs -legends(冰河); 2005-11-10 (#2600745@0)
    • hmm, go get another cable modem, hook it on the cable if ur ISP is the cable company. try try bah. I am sure u have cable outlet on the 2nd floor. -buma(buma); 2005-11-10 (#2600917@0)
