Setup:
DIR451 - Access to Internet, printers and SAN connected.
Security - Shared WEP Key
This works 100% and has for many years.
DWL2100AP - works fine when connected via cable to DIR451 as Access point.
However, as Repeater - wireless -

Settings: AP-Repeater, Selected DIR-451 MAC Address, Security WEP - Shared Key - entered same key.
Nothing connects to it. What is wrong?
Is there a set of more detailed instructions and trouble shooting somewhere?
(I'd post screen shots, but it appears not to be functional)
Cheers
