Problem with reauthentication

[Ken Wolstencroft]

I altered reAuthPeriod in eapol_sm.h to 9999 instead of the default 3600.
The reauthentication process then occurred after 2.7 hours, again
disconnecting the network connection.

Could this be a bug/misconfiguration in the reauthentication process of
hostap or an issue with Windows XP or the Dlink DWL-520+.

Any help would be appreciated.

Thanks,
Ken
