Similarly, I agree with Willot & Euromax.
I bought two WHR-G300N because my supplier said they now no longer stocked the WHR-HP-G54 which I have used several times previously for AccessPoint and 'boosting' using another as a Wireless Bridge.
I do not believe my supplier even realised that this unit does not support WDS!
Unfortunately I will need to look for an alternative unit / other manufacturer? (to use with NTL / Virgin Media)
Does anyone know alternatives that are available please
Many thanks
