I've got a new Netgear 3500L, which works great. The connection stregth is great and I'm happy in overall. This is a N router with upto 300Mbps. However, the connection speed goes only upto 20 something Mbps. Shouldn't I get 150 or 300Mbps instead? I tried to set wireless setup to switch from 54Mbps to 150 and 300 however, the speed actually dropped to teens. I wonder what's going on... Any tips on getting 100+Mbps?
