Asus DSL-N66U

[#1]

Just bought the Asus DSL-N66U to replace the technicolour and bt open reach modem but my speeds have dropped, anyone know of any specific settings that i might be missing to why its dropped?
Was getting 52mb download now only getting 40mb but as soon as plug the technicolour back in i get 52mb again.
Thanks

Can't answer your question but it seems your not the only one, i posted this in another thread on the forums to ask if anyone else was getting the same issue as i was looking at one.
