My hp6600 wireless printer worked with a zyxel modem but does not work with a rohs modem..any suggestions?
Sorry, Carl, you will want to check with the manufacturer of the router you are using to verify you have setup the 2.4 GHz band to properly communicate with your printer. Unfortunately, Rohs is not that popular of a brand, so you may find product support lacking for your device. Carl, using a more well known router brand from Amazon may be a better option for you.
