What does the app "Eduroam fixer" do? I can connect to my university's eduroam network but very often I lose the connection and cannot reconnect until I reboot the phone. Now I found an app called "eduroam fixer" in the market. What is this app supposed to do exactly, what does it differently to the built-in WPA enterprise support? I cannot properly test the app right now as I'm not anywhere near my campus.
Judging by the reviews on various sites, this app is unlikely to solve your need to reboot after the connection gets screwed up; users report the same thing occurring with the app.

This thread is particularly relevant.  It seems that "Eduroam Fixer" is just a configurator.  In particular it allows you connect to Eduroam by changing config files for you; this is useful on some ROMs which (for whatever reason) don't allow you to properly set the certificate through the interface.  I'm not 100% clear on the details, but the people in that thread consider it a security risk.
