Question Advice on buying a wifi usb adapter

[Saber_1]

Hey guys ,

I have a g31mxp motherboard that "DOES NOT" have a built-in Wifi support , anyway I bought a new router today "TP-Link W8961N" so I thought why not buying a wifi adapter so I can use it's better 802.11n features , anyway I came up with those 3 but I'm really confused which one to buy , since I found a 150mbps cost as same as a 300mbps ones so what's the difference ?

Do not buy the "nano" adapter. There is no space for an antenna so the performance is poor. Unless you are moving around, you will always be happier with wired. Even if you have to use powerline network adapters, they will be better than WIFI. Save the WIFI for devices that actually move around.
