OK - I first did not understand the problem, but after looking at the manual of the RP114 (if you don't have one, you can get it here
), things become clearer.
- Vocabulary: You say you "put a hub in between", but you connected the RP114 to the wall outlet and a computer to the RP114. Correct? The problem is that this device is not a hub, but a router.
- By installing a second router, you created a second network, that is not able to talk to your first network. That's why you can't get to the gateway.
- You will have to re-configure your RP114, so it can communicate with your first router. Actually, you will have to disable all "router" functions, especially DHCP.
So - how do you do that?
- Connect a computer to the RP114 and check your IP address by typing "iconfig /all" in a command prompt (Win-key+R, then type "cmd" and then "ipconfig/all in the opening window.) You will see that your IP address is somewhere in the 192.168.0.xxx range.
- Find the Gateway information.
- Look at the manual (pg.41-43) how to connect to the RP114.
- Start the wizzard. None of these settings are important, except pg.46 "WAN IP Address Assignment"
- Here you have to match the values to your current DSL router configuration. Let's say my first router has the following information:
- IP address (=Gateway) 192.168.1.1
- Subnetmask 255.255.255.0
- Now choose "fixed IP address" for the RP114 and set it to 192.168.1.2
- Subnetmask is 255.255.255.0
- Gateway is 192.168.1.1 (your first router)
- click Finish
What you did here is to integrate the RP into your first network.
- Now go to "Advanced Settings" (see pg.55 in the manual) and go to "LAN Setup".
- Disable DHCP. You don't want to have two devices handing out addresses - let your first router do that.
- Check the System Status (pg.67) and make sure all settings are applied: WAN should point to your first router, no DHCP on your LAN.
One last thing: whatever IP address you give to your RP114, make sure that you take that out of the DHCP pool from your first router. You didn't mention which router you are using, but usually they all have a setting that defines the DHCP range (see some examples pictures here
.) So if your first router's address is 192.168.1.1 and your RP's address is 192.168.1.2, start the DHCP range outside of these values. In other words: make sure that RP's address is NOT used by DHCP, or your setup might fail. You want to reserve that address for the RP only!
If you think that this is way too much trouble, you can always go here
and get a switch for under 20$.;-)
