Issuing more than one IP from switch and hub

Posted on 2005-04-15

Ok, let me show you first how our network is set-up:

Ok, up until this morning our all of the computers and the xbox had a perfect connection to the internet. But now only the office computer can connect to the internet. First I figured the dsl modem needed to be restarted. So I did this, along with restarting both the router and the hub. Nothing and same problem. I ended up calling tech support at verizon, and they led me to release the ip from the computer that got internet (Office) and then try using it on the other computer. Well, it worked. But now I don't have internet on the office computer. It seems that the modem (or whatever would be doing this) is only issueing one ip address. Every time I release it from one computer, it will connect to the next. I have tried various other ideas, such as reconnecting, checking for faulty connections and/or wires, restarting, re-installing drivers, but still with no avail.

Any help would be MUCH appreciated. And don't be afraid to use difficult computer lingo, I am much aware of everything about computers and don't need begginer idea's like, "try restarting your computer". And again, thank you in advance.

    I think your link is broken, so i'll try to guess your setup:


    The modem can only assign you one IP.
    That external IP will be the wan IP of the router, the LAN IP should be  in a private class (ie: or The router can also have a builtin DHCP server to lease addresses to your PC's. You could start by checking if the router's DHCP function is enabled and well configured.

    It seems that the our isp did what's called a 'move', where all of the ip's are switched to new ones. During this process the switch that had ever so efficiently worked in the past, stoped working (it wasn't meant for this purpose in the first place so it was a wonder it didn't happen earlier). So I went out and bought a Linksys cable/dsl router with 4 port switch and it worked like new. Plus, the router has alot of cool functions you can change in the config of it. But thanks for the help anyway.
