  1. We use true ip addresses on every single computer in my company. Let's say we have 10 computers. I tried to add a broadband router on our LAN to provide wireless access service . I plugged the network cable(from swtich) in router's WAN port, then I plugged another network cable(connect to my desktop) in one of LAN ports on the router. It worked for 5 minutes and then it disconnected itself.

    My desktop got an ip from the router (built in DHCP 192.168.1.2).
    The router's ip is true ip getting from DHCP server on LAN.
    It worked for around 3-5 minutes after I restarted the router. I tried many times and I got the same result.

    I was wondering what's wrong with the connection. Is there anything I did wrong?

    Thank you

    I have no idea what you mean by this. ALL ip addresses are true.
    I can only guess you have
    Code:
    isp--companyRouter---switch
    and you added
    1) you need to get the IP addresses coming thru the switch
    connect your PC to the switch, get a command prompt and enter ipconfig
    you'll get back something like IP Address. . . . . . . . . . . . : 192.168.0.4
    you have two choices
    1. use the new router to create another subnet (eg: 192.168.1.x)
      {connect the switch to the newRouter's WAN slot}
    2. or use it to extend the existing network, keeping everything on 192.168.0.*
      {leave the newRouter's WAN port empty and connect everything to only LAN slots,
      and you need to disable the DHCP service in the new router}
    (1) will isolate all systems from the company
    (2) will allow print/file sharing everywhere
