Hi,I am using a WRT610N Dual band router.My internet Provider is COMCAST.My standard UPLOAD/DOWNLOAD Speed is 22MBIT/sec.However by using my router the speed dips to 5 to 6 mbit/second.I have upgraded the firmware ,since then the speed on desktop is 19.3 and laptop is 8.2.I have used Speedtest.net and speakeasy.net to determine the speed
