Misc DS Lite error 51300 connecting to BT Home Hub v2

[Gaz777]

Sorry if this has been posted before but search isn't working.

Whenever I try to setup the wi-fi on my DS Lite it tests the connection and I get Error Code: 51300.

I've had a look on Nintendo description and solution of the error but nothings helped.

I'm trying to connect to a Black BT Home Hub v2.0, Software version 4.7.5.1.83 (Type B).
It's setup to WEP 64bit, 802.11 b/g/n

For some reason which I can't work out it always errors.

Any help is greatly appreciated.

thanks,
Gaz

EDIT:
After alot of searching I came to the conclusion the DS Lite just wouldn't work with the BT Home Hub v2.
So knowing it used to work on my older Home Hub I set it up connected to the newer one to give another wireless AP and now I can successfully connect my ds to the old hub which is connected to the internet through the new one.
