The 802.11n standard allows for speeds up to 600Mbps, but that's only with 4 antennas (and they must be used simultaneously). This one, with only 1 antenna, will max out at 150Mbps.
But that 150Mbps includes protocol and signaling, so your actual speed will be somewhat less. And then if there is interference (microwave, baby monitor, cordless phone, another router) nearby, it will drop even lower. And if the distance between the router and the adapter is too much, it will drop the speed even further.
So, if you are currently getting 60-120Mbps, that's perfectly normal. You probably have a single antenna router (even if there are two or three antennas, it may only be using one at a time). If you want to go even faster, go get a router (and adapter) that are rated for speeds up at 300Mbps (2 antennas), 450Mbps (3 antennas), or the maximum 600Mbps (4 antennas).
Of course, most people don't have Internet connections that come anywhere near 60Mbps, so if you're only trying to improve the speed of loading a webpage, a faster router/adapter combination won't help. Although, the faster combinations also have extended range, so there is a secondary benefit to getting one.
