I assume this is an issue according to the iwconfig output:

first authentication:
wlan0     IEEE 802.11b  ESSID:"OURNETWORK"  Nickname:"mycomputer"
          Mode:Managed  Access Point: "MACaddress of AP"  Bit
Rate:11Mb/s
          Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:110C-17E6-70   Security mode:open
          Power Management:off
          Link Quality:72/70  Signal level:-22 dBm  Noise level:-94 dBm
          Rx invalid nwid:0  Rx invalid crypt:144  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:35   Missed beacon:0

after 25 minutes (no reauth visible in radius logs):
wlan0     IEEE 802.11b  ESSID:"OURNETWORK"  Nickname:"mycomputer"
          Mode:Managed  Access Point: "MACaddress of AP"  Bit
Rate:11Mb/s
          Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:110C-17E6-70   Security mode:open
          Power Management:off
          Link Quality:72/70  Signal level:-22 dBm  Noise level:-94 dBm
          Rx invalid nwid:0  Rx invalid crypt:144  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:551   Missed beacon:0

As you can see, the line Encryption key is the same. From it I assume
that rekeying/reauth is not working. Is that idea correct?
