Topic # 89799 8-Sep-2011 09:20

I am in the process of connecting my old Belkin wireless router to my friend's Telstra cable. I have used this with telstra cable before so I know it works.

Does he have to physically phone TelstraClear to find out what his assigned IP address is or is there a way to check through the PC?

Also, do I have to set the connection to "Static" in the router settings? I was last on TC over 2 years ago so my memory is hazy on the exact setup.

Any advice appreciated.

Oh, one more thing, I noticed that one of the two TC cable modems he has would not connect to the internet through the router. I.e the internet light just flashed, but the other one which is connected to the connected to his T-Box would connect show all of the lights including the "connected to internet" light. Are these two boxes different in some way?

Although it showed as being "connected" obviously there is no throughput as I haven't got the IP settings right.

Thanks,

DLS

Hi, yes you do have to set a static IP address on the wan port, other than having the IP address noted or extracting it from the existing router (if there was one previous) or if his pc is currently directly connected to the TCL modem then go into the network settings and check the TCP/IP settings and you will find the detials there, otherwise you need to call TCL.

The TBox has it's own modem iirc, and it doesn't provide any net access. It's a private network for use by the TBox.

0508 888 800 is by quickest way to sort this. They can give you the netmask and gateway that you need as well.

He can connect directly to the internet using the TC cable modem so I will try what you suggested.

And the gateway address is the static IP with the last number set changed to a 1 is that right?

The DNS settings i found are
P 203.97.78.43
S 203.97.78.44

Have these changed at all?

No, there is no existing router.

Thanks.

In that case would the cable not go directly into the T-Box without going through an external modem first?
As it is TC have set it up with a standard cable modem with ethernet cable going out into the T-Box.

Tbox needs a coax and utp connection iirc.

It gets video on one and epg on the other and is set up to be able to stream movie content in the future (if they're not doing that now).

That makes sense, I didn't see what else was plugged in the back.
I last had TC in the days before the T-Box.

When changing the router you also need to wait for the ARP bridge table in the CMTS to clear before a new MAC address will work bridged behind the cable modem. This can often take up to 15 minutes before it's flushed and the new device will work. If you need to get around this in an emergency you'll need to use the MAC clone feature in the router to use the same MAC as the old one.

Can I get all of this info using the ipconfig /all command, will it show me everything I need?

You have to troll the TelstraClear forum a little bit more then ;).

It's common knowledge and been posted a few times here.

Hi, not likely to get it from IPconfig, you need to go into the NICs setup and extract it from the TCP settings of the nic, 1min work.

And yes the gateway is the same as the IP but .1 and subnet 255.255.255.0, off the top of my head those DNS's are correct.

I wish Babelfish had a techspeak to layman option.

Does this mean that at some point it might take the router 15 minutes to become the default gateway?

So at what point in the process would this waiting game start, just so I can go have a cup of tea and restart everything and not be sitting there wondering why it still isn't happening?

It means that the gateway (TelstraClear equipment) will only allow one MAC address to be associated with your IP address at a time. This information is kept at the gateway and refreshed every fifteen minutes.

So if you change routers, or change from a PC plugged to the modem to a router, you might have no Internet connection for up to fifteen minutes, when that entry in the table is updated automatically.

Gotcha, saying it like that makes sense to me. Thanks Mauricio
