cipher_list = "DEFAULT at SECLEVEL=0"
tls_min_version = "1.0"
tls_max_version = "1.2"

These options doesn't say that freeradius should support all tls  
versions until 1.2? Why freeradius wouldn't like the TLS version used  
by the client?

And why sometimes the same clients are accepted?

I have another freeradius server version 2.2.5 that don't have this  
problem, all users can use the internet no matter the client's tls  
version.

These are android devices that can't upgrade. I can't ask the students  
to buy another cellphone and I need to allow them to access the  
internet.
