Device can't get access

Hi, I'm trying to configure a Lantronix Matchport bg Pro to access my wireless network. I seem unable to configure it to give it access, and I don't find why. My freeradius (3.0.10) can authenticate laptops and smartphones, it's only the device that gives problems, so I think I'm doing something wrong on the device. Below is my debug log for the device. I think in section (5) is my problem : (5) eap_peap: ERROR: SSL says: error:1412E152:SSL routines:SSL_PARSE_CLIENTHELLO_TLSEXT:unsafe legacy renegotiation disabled Is it possible to enable SSLv3 (temporarily), so I can see if that really is the problem ? Thanks, Koenraad.
