the question might seem naive, so please be kind

I'm looking for a ADSL modem with a built in WiFi router, for a home setup, that I can configure via the WiFi link. Something where I won't need to use the serial or ethernet cable to connect to in order to get the access to the modem to set it up. Say connect to it only via the local network address, with username & password to tweak the settings.
Haven't had to do this sort of thing for a while, so this might be a default option now days with the latest hardware. But I'm a bit out of touch so I'm looking for some recommendations from you good and patient people.
Thank you for your time
