ALL wireless is crackable as far as piggybacking your internet goes … depends how paranoid you are about your neighbours, if you’re VERY worried, don’t use wireless at all 
So you’re saying you can create the wireless connection without it spitting the password back at you ?
Have you tried deleting ALL wireless profiles, and creating a fresh connection ?
If I were you I’d try a different wireless adapter.
These tiny little things:
Edimax EW-7811Un 150Mbps Wireless IEEE802.11b/g/n nano USB Adapter
work “out of the box” with Peppermint 4 (so should do the same with Ubuntu 13.04/Mint 15) … and my Sky router is using WPA2 / AES
(I’m also able to use it to connect to a friends Technicolour router … can’t say for sure if he’s using WPA2 though)
ok thanks me ol maties
Next time i update this thread I will be on Peppermint…wish me luck!
I was being specific about that Edimax wireless adapter and Peppermint 4 … not YOUR wireless adapter, which I’d expect to have the same problems under Peppermint 4 as Mint 15 as they’re both based on Ubuntu 13.04
(unless of course it was a Mint specific issue … which I doubt)
With YOUR wireless adapter, you MAY have more luck compiling the ralink drivers in Peppermint 3/Mint 13/Ubuntu 12.04 LTS
and oddly, any of those 3 will have longer support than Peppermint 4/Mint 15/Ubuntu 13.04 … as they’re all based on the last Ubuntu “long term support” release.
But good luck whichever route you take 
[EDIT]
If you decide to try Peppermint 3 rather than Peppermint 4 … don’t use the download links on the Peppermintos.com website, for some reason they’ve put up the original, not the later respin that fixed some bugs … use ONE of these links instead:-

Ok Thanks
Will get the USB adapter recommended. I am now using Peppermint 4 and its slick! Watch this space!
Peppermint 4 is a keeper. Very good all round. V Fast and smooth and with only 1GB mem.
I’d like to say that I found your solution worked for me too - I used the dropbox driver and followed your instructions and got my ralink wifi working.
I was a bit iffy about using some modified driver, but I’m making a leap of faith that you’re a good guy, so now I can use my rt2870.
It was a big help, thanks 
But how did you do it - why don’t the ralink drivers i get on disk or download from their website make or install properly, but yours does ?
I also, BTW, am finding that installing debian firmware-ralink package will get my rt5370 working, but not rt2870 - even though the rt2870 is listed as one it should run.
Anyone know why ?
To tell the truth I can’t remember what I edited in those drivers, but it would only have been one or more of the following:-
a) edited the config file to support WPA supplicant through networkmanager
and/or
b) added the vendor:device ID strings for a particular wireless device … so the correct drivers are loaded when that device is detected
and/or
b) changed a few calls so the drivers compile correctly against recent kernels. (the ones on the ralink site used some old calls that are no longer used in recent kernels)
I guess you’ll just have to trust me
(or compare mine against the originals)
OK thanks I at least get an idea of what that stuff means now.
But why doesn’t the deb package for ralink drivers work for all of them ?
I’ve got a few ralink usb’s now and only the rt5370 seems to work right out of the box. I’ve got three and never had a problem.
The 2870, although listed as part of the firmware-ralink package always seems to need your tweak.
I’m a noob at this so I wonder if it’s something simple like un-blacklisting the rt2870, or using modprobe ?
Has the kernel development left the rt2870 behind ?
I went here for the package - Debian -- Error
I guess I could have added the repo instead.
Ah, I see a whole thread on the 2870 so I will read that before asking more . Thanks.
Sorry lostgnuuser, I got a bit busy trying to recover a Windows PC for someone 
If you’re still having problems with an rt2870 based adapter, please start a new topic and we’ll take a looksee at it
(will have to be tomorrow though)
Just a quick thanks, as your instructions were very easy to follow and worked like a charm! Appreciate people such as yourself who share their knowledge with others!
Best regards,
Greg
Hi Greg … you’re most welcome, thanks for the feedback
