Losing WiFi connection after a while: `Group rekeying complete`

Hi everyone! I'm trying to use my Campus' WiFi connection over an Arch Linux x86_64 Enlightenment system installed on an ASUS U36SG.

As instructed by the University, I imported my personal .p12 certificate downloaded from the Campus and extracted my personal pem certificate, my private key and my CA certificate from it. After that, I created an /etc/wpa_supplicant.conf file as follows:

ctrl_interface=/var/run/wpa_supplicant
  network={
  ssid=%CONNECTION SSID%
  proto=WPA2
  scan_ssid=1
  key_mgmt=WPA-EAP
  pairwise=CCMP
  group=CCMP
  eap=TLS
  identity=%CAMPUS IDENTITY%
  ca_cert=%PATH OF CA CERTIFICATE%
  client_cert=%PATH OF PERSONAL CERTIFICATE%
  private_key=%PATH OF PRIVATE KEY%
  private_key_passwd="CERTIFICATE PROTECTION PASSWORD"

After this, I run in my terminal

sudo ip link set wlp3s0 up
  sudo iwconfig wlp3s0 essid %CONNECTION SSID%
  sudo dhclient wlp3s0 & sudo wpa_supplicant -D wext -c /etc/wpa_supplicant.conf -i wlp3s0

The connection works. Anyway, I get a spammed `wlp3s0: WPA: Group rekeying completed with 20:b3:99:1c:a8:b8 [GTK=CCMP]` message, and after some time I'm connected internet stops to works with no apparent error message, and no variation at all in the terminal output. The message continues to get periodically spammed, usually with 30 seconds between one time and the other. This is the complete terminal output on the last command (no message is displayed for the other ones):

Re: Losing WiFi connection after a while: `Group rekeying complete`

The group rekeying is usually issued by the router/AP you're connected to. At least my router has an option to set the rekeying interval. Your university seems to have set it to 30 sec.
I don't think that's causing your connection problems.

What wifi module do you have?

I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do.  (Gune | Titan A.E.)
