André,

I am sure you understand why I do not answer requests for debugging from E-mail 
that is sent to me alone.

Does the card work at your house? You need to be as clear as possible in what 
you write.

What are the details at the University? How far are you from the AP there? What 
kind of encryption is used (WPA, WPA2, etc.)? How much interference is there on 
the channel used? Posting the output of 'sudo /usr/sbin/iw wlan0 scan' will 
answer that.

For debugging, please try the following commands:

sudo /sbin/modprobe -rv rtl8187ae
sudo /sbin/modprobe -v rtl8723ae ips=0

Does that help?

When the disconnects happen, what is the indication in the output of dmesg?

Finally, we need to check your firmware. The md5sum values for the fw on my 
system are

ce50dfe07dbb1bfe9e14bdb315a4b28a  /lib/firmware/rtlwifi/rtl8723fw_B.bin
69ccaffbe94cc0ef1b89c25290e19b2e  /lib/firmware/rtlwifi/rtl8723fw.bin

 From the dmesg output, which one is being used on your system?
