Title: router to an external modem
Post by: A+ fail on December 28, 2008, 10:20:43 AM

Hello All.

I have an external modem that my ISP sent me for my XP PC. The phone line connects into it and out the other end comes the ethernet cabel into the back of my desk top. Everything works fine.

I bought a TP-Link router as I want to add other PC's and the instructions say connect the phone line into the router and then connect the ethernet cables from the sockets to the other PC's. To do this bypasses the modem and therefor it wont work (should it?)

My question is - Can I take the Ethernet cable from the modem and plug it into one of the router sockets at the back (bypassing the phone in conection) and thus get the network set up. Also would I need a straight through cable to do the modem to router connection?

Thanks

I'm assuming you have DSL (high speed Internet through a phone line that doesn't interfere with phone calls).

With one computer, the order is

Computer ----- Ethernet cable -------- modem --------- telephone cable -------- wall jack.


With a router, it is:

Computer A ------- Ethernet cable --------- router LAN port (numbered 1, 2, 3, or 4)

Computer B ------- Ethernet cable --------- router LAN port (numbered 1, 2, 3, or 4)

Router WAN/Internet port -------- another Ethernet cable --------- DSL modem ---------- telephone cable --------- wall jack.

Thanks for that - This bit I understand

(Router WAN/Internet port -------- another Ethernet cable --------- DSL modem ---------- telephone cable --------- wall jack.)

But the is no Router WAN/Internet port on the router, just a phone connection for modem and 4 Ethernet ports for networking.

Do I use one of these ports for the connection to the DSL Modem?

It's a TP-link TD-W8901G

Your router is a ADSL router and not a standard DSL router.

Check out chapter 2 and 3 for the setup of this router.

I would suggest you replace it with something like a linksys WRT54G.

Thanks again. I have seen this and cannot understand why in fig 3.4 I have no sub net mask  or default gateway boxes to fill in on my OS. It's XP home, with service pack 3 on it. Any suggestions.

I have pinged the system as the guide told me and got success.

Just found out that I had not gone to the IP address 192.168.1.1 & typed in the ISP passwords.   

Thanks for your help and happy new year
