Broadband Router

ClonmelMan · 11-02-2003 4:32pm #1

I am having problems setting up a Billion broadband Router with Chorus cable, just can't get connected when the router is in place. Also if I change anything in my setup I have to phone them to have my connection reset. Anyone else have any problems like this or any idea what I can try to fix it.

Thanks in advance.

How do you connect to Chorus when everything is working? Do you have to use a PPPoE client on the PC? Or is youc connection associated with your MAC address?

When you say "change anything in my setup", what do you mean?

Chorus say that it's the MAC address of the modem but just in case I have cloned the MAC address of the NIC on to the router and still no joy. I have it set to obtain an I address automatically.

If I change my PC or NIC or even try to use the USB connection.

Hmm, how to tell whether the problem is that the Router isn't communicating with the modem, or that Chorus is refusing to talk to the router. I presume you've checked the WAN link light on the router - are there any lights on the modem that would indicate whether the modem and the router are talking to one another? (are you using a straight through or crossover cable between the modem and router)?

Sorry I can't offer more specific advice.

Yes all lights are on and I use a crossover cable when connection to the router and straight when connecting without the router. I can ping the other PC on my LAN but cannot ping on the WAN side of the router not even the modem.

But if you plug in the router, decide it doesn't work, and then put everything back the way it was, you don't have to get things reset?

By the way,
this page suggests that you may need to power cycle the cable modem when making changes, though if you've cloned the MAC address properly, that shouldn't be an issue.

And the cable between the router and the modem? If you're using a straight through cable, have you tried a crossover cable instead (and vice versa)?

I can ping the other PC on my LAN but cannot ping on the WAN side of the router not even the modem.

Have you tried to plug one PC in on the WAN side of the router, and the other on the LAN side, to see if you can get anything through the router?

(Sorry if these are all obvious suggestions).

I have tried every thing else but that, silly me. What cables would I use on the WAN side ie:crossover or straight? or maby I should try both.

If one doesn't work, try the other. The Link lights on your NICs and the router should give you an indication of what's going on.

Have tried that with no joy, lights but no action. Any other ideas?

Not really. If you can't get packets through the router just using 2 PCs, then I presume it's a problem with the router.

Did you set the Router and the "outside" PC to use appropriate staic addresses and netmasks, and did you try to get packet out from the "inside" PC to the "outside" PC? (The NAT in the router should blocks inbound traffic, but you should have been able to ping the WAN interface from the "outside" PC).

I'm afraid at this point, you need to compare this to someone elses set up - do you know anyone else in Clonmel with a router?

Could not set a static IP in the router as no matter what settings I used it gives an error saying the either the Subnet Mask is invalid or that the Gateway is invalid. BTW thanks for all you help

I think that is the source of your problem right there .... If you do not have a netmask or gateway specified in the router then the pc's connected to it do not know how to route traffic through it ... try to get a firmware update or something for your router, it could be some sort of a software problem thats stopping you from specifying them. Every router must have netmask and gateway set, check all your manuals etc (RTFM

)...

I just saw this site http://www.megapc.com.au/BIPAC-643Optusnet.htm that shows how to get yourself going with cable modem (alright its for a cable company in australia... but the general setup should be similar) ... give it a shot ,,,you never know... (and if it does not work, try a different type of cable (straight versus crossover) between the modem and the router and try again ...

I set it up exactly as this site suggests and every thing looks the same but still no joy. I have also updated the firmware to the latest version. It's either a fault with the Router or my ISP is blocking it. Should I be able to ping the Cable Modem, I can when the router is not connected but can't when it is.

It may be worth your while asking them for a static IP ... which would simplify things ... it seems to me that its just a configuration thing on the router ...

btw ... chorus cannot tell how many pc's you have connected if you are using a properly configured router with nat (if they tied your network card mac address to their modem all you have to do is change the mac address on the wan port) ...

The thing is that if you had no broadband and just used the router as a 4 port switch you should still set the netmask 255.255.255.0 and the gateway in this case is the ip of the router 192.168.2.254 on each of the pc's connected to the router... I suppose you also have dhcp turned on in the router

I would check your cables as well ... remove the one that is supposed to go between the modem and the router and put it between one of your pc's and the router ... if the pc can still work on the lan you will know it is a straight cable,(if you have an old OS you may need to reboot) if it will not work on the lan then its crossed over....

Other than that I'm at a loss ...

BigEejit · 15-02-2003 5:38pm

last thing that it might be ... routers usually need to be told what protocol they are using ... PPPoE or PPPoA, I dont think that you will get a connection if you have the wrong one set ...
Try to find out what chorus use, or just change it yourself (making sure of course that all your other configuration and cabling is correct)

Yes, you should be able to ping the Cable modem, if it's pingable when you are connected directly.

Make sure it is the cable modem that's responding by disconnecting it from Chorus - if you can't ping it when it's disconnected, it might be that you're getting a response from the next thing down the line, in which case the lack of a ping response is less helpful for diagnostics.

I can log onto the modem config when the Router is not connected but can't when it is, and same with ping. The cable between the modem and Router is a crossover. I nearly sure now that the problem is in the Router and I might return it but I would like to have some kind of test to be sure that this is the case.

BTW thanks again for all the help.

If you can't talk through the router when you have a PC configured on each side, it looks like the WAN interface isn't working. Unless you know someone else locally who also has a router on Chorus, your best bet is probably to return it.

No problem.
