First of all, once I started down the path of attaching the Tivo box wirelessly to my home network, then I found that there was no 'cancel' everything button on the remote.

This is what I have:
DSE XH9950 Modem/Router.
I know the SSID
Authentication = WPA2-PSK
Encryption = TKIP
IP Address (router): 192.168.1.2
DHCP = Enabled
DNS Relay = Use Auto Discovered DNS Server Only.
I know the Pre-Shared Key
Dynamic DNS = Deactivated

I have 2 PC's connected to my network:

A) Vista Desktop PC with IP Address: 192.168.1.10, Subnet mask: 255.255.255.0 connected directly to the Router.
DNS Server = 208.67.222.222 and 208.67.220.220

B) Wireless XP SP3 Netbook PC with IP Address: 192.168.1.20.

I have recorded both the MAC Address for both PC's in the Router and the 2 PC's are working as usual.

I have added the MAC address for the Tivo box (as given on the screen) into the Router.

So far I have I had message DN02 and then DN06 from the Tivo box. The URL (for example) www.mytivo.co.nz/errors/N06 does not exist.

I have powered off the Tivo box and even though I have dis-connected the wireless 'thing', it still wants me to set up the connection to the network.

I set up my home network over a year ago and the memory fades, so please don't assume I know a lot.

Please help.
