Panasonic DMR-PWT635 Won't Connect to internet

[#1]

Hi,
I am not particularly clued up on IP's, DNS's and Gateways, and usually rely on auto setup functions.  However, I have today bought a Panasonic DMR-PWT635 and the easy setup to connect it to my WiFI has not worked (even after several attempts).
I have a Standard PlusNet Router (having only joined 2 months ago).
On the device I go to Easy Network Setting (Home Network Connection Check) and I get the following Results:
1. Wiresless Setting - Pass
2. IP Address Setting - Home Network Available
3. Connection to Gateway - Fail
Looking in the trouble shooting section of the manual it says Check "settings IP Address, DNS settings".
I have know idea what this means, what I should be checking or what to change.
Any help to get this device connected would be much appreciated.
Thanks

Try setting the IP etc manually
IP address 192.168.1.200
Subnet 255.255.255.0
Gateway 192.168.1.254
DNS server 8.8.8.8
See if that helps

Thanks Managed to connect manually using the codes on the related thread.
Just need my broadband speed to be increased as everything keeps freezing!
Thanks for you help.

Welcome to the forums.
First I would suspect wifi congestion.  Streaming over wifi is not ideal, are you able to get a wired connection for the TV?
Also take a look at the speed issues thread and post the requested data under a new thread with a relevant title please.

@mods,
Merge this thread with the referred too TV problem thread ... Or lock it?  

@CRT,
Given that this is a reoccurring theme, can products raise the issue with TG to find out what is going wrong with the DHCP offer process here?  It sounds not unlike the issues I have reported with Vista platforms.
