Issue with network

[Sam334]

Setting up a network in an office building... I was handed a piece of paper by their network admins with the following info: ip address, subnet, default gateway, and 2 dns servers.

The network will consist of one desktop and two laptops connected via wifi.

So, here's how it's set up:

Router set to "Static ip" with the ip address given to me by the office building, their default gateway setting, dns info, and subnet. Let's say it ends in .x

I then set the router's IP as .x+1 and enabled dynamic dhcp to give ip address in the .x+2 to .x+4 (one for each computer). I can log on to the router from each networked pc, but can't seem to get internet access. When I set one single computer and connect it directly to the lan port with static ip settings as described in the previously mentioned handout, the single computer works and connects to the internet which pretty much tells me it's something in the router's settings).

Any ideas would be greatly appreciated.


edit** I also set each pc to use the static a static ip within the range set on the dhcp settings within the router. The gateway on each pc is set to the router's ip and DNS servers are set to the settings on the paper I was handed. The problem remains.

you may need a crossover cable for the router to router setup. may explain by the workstation works while directly connected.

The router is connected via an ethernet cable to a jack in the wall, not directly to a router. Would I still need that?

yes, a crossover will still change the send/receive pairs. their pretty cheap, and it may explain why the same settings won't work on the router tho it works on the PC. if that doesn't fix it, i would start checking your router settings to ensure they're correct.

You can't have the WAN side and the LAN side of a router on the same Subnet. It won't work.

Set the WAN IP address to the Static IP given to you. Similarly, set the Subnet Mask the Default Gateway, and the DNS Servers as you were told.

On the LAN side of the router, set it to ENTIRELY DIFFERENT SUBNET. If your WAN IP address is 70.x.x.x (for instance), set your LAN IP address scope to something like 10.0.0.x, with subnet mask 255.255.255.0. Set the router's LAN IP address to 10.0.0.1.
Turn on DHCP and set the DHCP address range to 10.0.0.2 to 10.0.0.99. That'll give you plenty of DHCP IP addresses for your internal network (LAN), while giving you addresses from 10.0.0.100 to 10.0.0.254 for any required Static IP addresses (such as networked printers and Servers.
