Which card do I need for wifi on laptop?

If you don't know you need the extra features in the latter two, you probably don't. So, the fist one.

> Will I be able to change the mac address on these?

Don't quote me on this, but I think MAC addresses are unchangeable. Tails does something to spoof them, though. I don't know anything about how this works.

> I think the place I get my wifi is discriminating against my mac address on my wifi card because when I use a different usb wifi card it works a lot faster than the one with the antenna also the computer they have there for you to use if you don't have one the wifi is much faster on there and it doesn't have an antenna.

I doubt it. Why would a wireless network make a deliberate effort to slow down your specific device's connection? I can't think of any reasonable motive.

There could be all kinds of reasons for one network card performing worse than another.

> Is this illegal to do in a public place to discriminate against certain mac addresses at a public place?

I don't think so. If you run a wireless network, it's your choice who you offer access to. I'm pretty sure throttling access for certain MAC addresses wouldn't be any different in this sense than encrypting access to the network and requiring a password given only to certain people.

> I was comparing performance between these two.

Those both have the same chipset. The difference is the second one has an antenna which extends its range.

I read that some wifi cards support mac spoofing but some don't. I have been able to spoof my mac address before on different hardware just not this one with same methods.

May I ask you what do you hope to achieve by spoofing your mac address?
