I had a SpeedStream 5100 modem connected to a Dynex 10/100M Router connected to a Cisco 1200 Router. I needed the additional ports to connect several computers. I installed a HP 3052A Wireless Printer to print from two iPhones and and iPad. I set up a network to accommdate the wireless devices. Things all work well until I started having problems with the Cisco router. I decided that it would be more streamlined if I could get ride of three devices and just have one instead. I purchased the A.T.&T. NetGear Gateway Router and set it up with my network. All my wireless devices work fine with the exception of the HP wireless printer. I can find the printer on all my wireless devices when I first turn it on, then in about and hour or so I can't find it at all. If I reboot the printer, then everything is fine for about a hour or more then it drops off the network. The Router is sitting up on a book shelf 7 feet off the floor with no obstructions, and the printer is within 8 feet of it. Does anyone have any ideas as to why the printer keeps going off my network?
