DCHP Router Problems

Hi. I'm having a really strange problem with my router. Its currently set up on 192.168.1.1 and DCHP is active, yet if I set up Windows to connect to the thing via DCHP it refuses and keeps a 0.0.0.0 IP address whilst trying constantly to get a real IP addres. It doesnt assign itself a private network address, just keeps hammering away at DCHP.

If I set the connection up manually, with IP as 192.168.1.2 and gateway as 192.168.1.1 it will connect to the router, but not to the internet, for that I have to add the Force9 Gateways into XP's networking thing.

I've had a look around and everything seems fine. The DCHP server says..

Current DHCP settings: Starting IP Address: 192.168.1.1
Number of Addresses: 254
Domain Name: ramphome.com
DNS 1: 212.159.6.9
DNS 2: 212.159.13.49
Default Gateway: 192.168.1.1
WINS IP Address 1: 0.0.0.0
WINS IP Address 2: 0.0.0.0
Scope ID:
Node Type:


DNS is..

Enter the DNS addresses provided by your ISP. Primary DNS Server Address: ... 212.159.6.9
Secondary DNS Server Address: ... 212.159.13.49


Though when I configured the router to connect I left the fields blank so they would be gotten from when it connected to Force9.

Does anyone have any ideas?

Oh, before I forget, routing..

where ***.***.***.*** is my IP address.

Please help. Thank you Smiley

Since your router has the 192.168.1.1 address, your DHCP range should NOT start at that address -- it can't be assigned to anyone else. Try starting at 192.168.1.2.

Also, I'm not sure of the 212.159.6.9 address for DNS. I thought the addresses usually stated for ADSL were 212.159.13.49 and 212.159.13.50 (though you could use 212.159.11.150 if you like to have them in different networks). Do you need to specify these at all, though, I wonder? -- doesn't the router get them automatically (itself using DHCP to configure its WAN interface?) -- and then use its own address as the DNS server when configuring its own DHCP clients (ie the PCs in your network).

Hi,

212.159.6.9 as well as 212.159.6.10 are two new caching DNS servers located in our Telehouse North datasuite.

If you are using Windows XP, go to Service in the Control Panel and ensure that DHCP Client is running. If it isn't you won't be able to pick up the IP details via DHCP.

Thanks for the replies, I did a clean install of XP and its all working fine now, guess I must have installed something that didnt agree with my networking. Shockedops:

For the 212.159.6.9 should I use the ones my router sets for me (.6.9 and .13.49) or configure the router to use .13.49 and .13.50?

Glad to hear it's working (and interested to hear about the new DNS addresses -- perhaps I'd seen a note about them, but it has slipped my mind! -- Why is it I can't find the support page that details all this stuff any moreHuh)

As far as using dynamic or manual configuration of the router is concerned, it doesn't really matter -- as long as it works! The dynamic, though, stands a better chance of working indefinitely into the future, for if you configure it manually, you'll need to make manual adjustments if Force9 change their arrangements for any reason at some point in the future. With dynamic configuration, changes should get picked up automatically.

Also the use of the 6.9 and 13.50 addresses implies a more resilient DNS setup than both on the 13 network -- I recall "narrs" having a go about this a while back (that might entice him out of his hibernation!!!).
