if i were you, i would try some soft solutions before i started replacing hardware...
is it still under warranty? did you try seeing what they said at the fruitstand?
what does "acting up" mean?
a faulty wifi card is generally a fairly binary thing - it works or it doesn't. your problem is probably either upstream of the card itself. if it really is a hardware problem it's more likely on the router side rather than the card.
have you tried other devices on the same hotspot? have you tried your MBA on different networks?
Is it slow when you connect to other routers? My 2012 MBA wifi is very speedy.
Maybe your wireless router has poor signal strength.
If your MBA is a 2012 model, it is more than likely still under warranty.
Try holding the alt-key and clicking on the wifi symbol. That gives some more information about the WiFi connection. The signal strength is the "RSSI" field in the menu. What does it say?
If the signal strength is in the range of -80 to -100, it's bad reception. Anything between -20 and -80 is ok (closer to 0 = better, but I don't think you can get better than -20 even if the laptop is sitting on top of the router). Typical value should be maybe 60-70, depending on router / walls / distance to router and such. If you have very bad signal strength even though the computer is fairly close to the router, it might be a bad antenna on either side. It can also be that the channel used is interfering with something (other wifi networks, microwaves, or whatever), you can try changing the channel in the router settings.
