My home network is driving me nuts. I am losing 50% of my speed through my Netgear Router WNR2000v3, wireless or wired I get 10.7Mbps but if i connect the computer directly to the cable modem I get 25mbps. I've spent a couple of hours tweaking settings and such and i'm pulling out my hair. For the speed tests i've used various test sites with similar results.

Performed a hard reset and restore settings on the router with no change. An additional detail I did not add, I removed the router and connected a 10/100 switch i have to the cable modem and received the same results, half speed. When i contacted the cable company they indicated they only guarantee the speed to one computer and often see a significant drop when connected to a router or switch.

 
A router can slow data down, but it is usually minimal. If your router has SPI (stateful packet inspection), try turning it off and see if your speeds come back up. Also, the make/model of router can make a difference as some use better chipsets than others.

Make sure you test it hard wired to the router. There are too many variables when testing wireless.
