The 15.5 attenuation is a router bug ( software glitch ) your attenuation will always be 46 / 47. but you still should get more speed than 3mbs with an attenuation of 46. You need to check your internal wiring / extensions... If you plug directly into the master socket with nothing else plugged in you should see your sync speed rise.
Use this
http://dg834gt.mognuts.com/NetgearRouterUtility.html ..... it gives you detailed stats on your line to see what your max sync line potential could be. Just open the .cfg file it creates with wordpad.
