Routers, Switches and Hubs oh my!!!

[cranebill]

Ok here is my scenario maybe you guys have an idea.

Server to Hub
Hub to Switch (to share a connection)
Switch to Wireless Router

Ok now here is my Dilemna
Also on the switch is a network printer, a network scanner, and a winfax server, all with static TCP/IP settings. Since we bought the wireless router which has a 4 port switch also built into it. Now I figure ok I have a switch built into the router so why not bypass the original switch, so i attempt this and well it does not work. I went and checked the ip settings of a laptop using using a wireless connection being set by dhcp and of course it is not the same as the static ip addresses set by the server.

Server sets address in the 192.168.0.1

Router is setting addresses in the 192.168.1.1

How can i get it to work as a switch instead of a router i guess is the question here. It is Model # WRT54G

Any help would be appreciated.

In the router setup page change the LAN address of the router to 192.168.0.1.

A Couple Questions on that. The NIC connected to my server (2000 Server running NAT/RRAS for Internet Connection Sharing) has the ip address of 192.168.0.1 so that would probably conflict. I guess a better question would be how can I get the computers connected to the wireless router to get their Ip addresses from the server instead of the router? Being that the network printer etc all have static ip's they need to be on the same "network" as everything else and the way it seems it is on a different "network". I have tried disabling DHCP on the router and then the computers running DHCP recieve 169. blah blah blah ip addresses.

OK... as it turns out i was setting things up correctly to begin with. On the basic page I set yhe ip address to one used in my existing network and disabled DHCP. On the advanced settings tab I made it a router instead of gateway. The problem I found which is still confusing to me was I went from a normal LAN port on my hub to the Uplink port on the new router with a straight through cable(in theory this should be correct, right?) but after just messing around I putit from a normal LAN port on the Hub to a Normal port on the router... now everything is peachy. Shouldn't I need a crossover cable for it to work that way? Heck I dunno it works now though and if anyone can clue me into the port to poet theory's i was talking about to tell me if i am wrong or not that would be greatly appreciated.

If I'm not mistaken, the uplink port on the router is essentially there to serve as a WAN input when using it as a router. When disabling NAT and DHCP, it becomes a 4-port switch with the uplink port disabled.

I could be wrong, but that's the way I understand it.

Just out of curiousity, is there any particular need for the HUB that you're using? Can't you just go from the Server -> Switch -> Wireless Router Switch? Hubs divvy up bandwidth among all ports in use. So a 4-port hub with 4 devices connected at 100MB/s would be essentially giving 25MB/s to each channel. A switch on the other hand will only give the requested bandwidth to each device as needed, meaning that at any one time a device could be receiving close to the full 100MB/s.

Well the idea was to get rid of the switch and replace it with the wireless router. The hub was in place when I got here but it goes from:

Server ===> Hub (same room)
Hub ===> Wall Outlets
1 of the wall outlets ===>Switch(now a wireless router acting as a switch)
Switch ===> Network Printer, Network Scanner, WinFax Server, and all Laptop connections (via wireless)

hi,

For the WRT54g to function as a switch you simply plug it to a REGULAR PORT ( 1,2,3 OR 4 ) not the INTERNET port.

This disables the NAT / Firewall feature of the router, turning it into a switch.
