i'd like to replace my usb adsl modem with a combo modem/router that i'll buy elsewhere other than my isp, but how can i determine that it will work with my isp, cuz from them i'll get only the modem (not the router) which is attached to an ethernet service plan should i take its modem)
any ideas on the specific modem/router i should buy based on my modem & isp info (if it matters):
usb adsl zyxel prestige 630 from cable & wireless(non-us isp from panama)
