Okay, here the situation I have a DIR-655 connected via ethernet to my pc downstairs and connected wirelessly to my Aluminum Imac upstairs in my bedroom. I got the 655 because i wanted an N router and have really good signal all over our house. My imac gets like 13mps on wireless N, with 50% connection. That is strange, I upgraded the firmware to 1.32NA but it didn't help anything really. My Imac disconnects about every 15 minutes, this is extreamly annoying. Yesterday I brought it downstairs in the same room with the router, honestly its not the far, and I thought this router could handle like 500 feet according to the box.. Anyways, right next to the router it obviously got full connection (130mps,100%) I have tried everything I could think of, unplugging the modem, the router, upgrading the firmware etc. Someone help. im tired of dissconnecting all day !
