Connections works for a computer, but not computers on a hub

[LadySlinger]

Hello,

I currently have a network that has a hub with 2 computers on it that connects in the network closet. I also have one computer that connects to the network closet. Both currently point to the same router and talk to each other.

I've been trying to switch these computers to a new router, but when I set the IP settings the similar (3 different static IPs in the router's range, same gateway, same DNS settings) The computer that connects directly to the back can get internet access, ping the router, etc. BUT when I go to the computers attached to the hub, neither have internet access, neither can ping the router or the "lone" computer.
I have double checked my TCP/IP properties and all match up with the lone computer who has internet access.

Any ideas anyone?

Thanks!

Is the cable from the router to the hub a 'crossover' cable or straight-though? Does the hub or router have an uplink port and what ports are currently being used?

 

[LadySlinger]

The router to the switch is a "Cross Over" that is placed in the first port.

I have the laptop going into port 5 via straight and the cable from the hub go into port 4 via straight to the uplink port.

What happens in the network closet? do the cables from the lone computer and the hub go directly to the router or do they go through other equipment first? As I understand all was working then you changed to a different router now they don't work. Weird

LadySlinger, I'm not sure I understand your answer. Is there a switch involved in addition to the hub; or are you referring to the same device?

Anyway, the pc's should get straight through cables from the regular ports on the hub. For the router to hub connection you have a couple of choices:
1. regular router port to regular hub port with crossover cable.
2. uplink router port to regular hub port with straight cable.
3. regular router port to uplink hub port with straight cable.
Also, be aware that for many hubs/routers/switches using the uplink port often disables the adjacent regular port, so don't try to use it.

Sorry until you pointed it out, I did not realise that I left the switch out.

The switch is connected to the router. I have the hub with the two computers connected to the switch and the laptop to the switch.
Between the switch and the router is a X-over that goes into the first port.
Between the switch and the laptop is a straight through. Between the switch and the hub w/ 2 computers is a straight thru cable as well.

Hope this is more information that will help!

Between the switch and the hub you need a crossover. Either physical or in the uplink port ( unless you have an autosensing switch or hub.

Can you by pass the hub altogether and plug your two machinges directly into the switch? You will increase your network speed for those machines.

Ghostin:
The two machines are across the office from the network closet.

It's almost like the router only wants the laptop to connect to it. One thing that I Have noticed is that when I do plug the hub with the two machines into to the "new" connection, the uplink on the hub begins to blink really fast and not in sync with the two machines indicators

Sounds like what Franklin said, you don't have an uplink port on your hub, so you will need a crossover cable.
