installed CA certificate not showing up in the list when connecting to a network

[ghylander]

there is a 802:X network in my uni which requires a CA certificate to log in
I didnt have any problem witht my previous phone (Sony Ericsson Xperia Arc S) but now I got a Sony Xperia T and i can't connect
I installed the CA certificate and if iI check in the installed certificates list I can see it right there, but when I try to connect to the network it won't just show up in the "CA certificate" list, only "unspecified" shows
any thoughts?

Speak to your Uni's IT department as the certificate maybe old and may need resigning to work with newer firmware on newer devices - It may work with other manufactures but it may still need signing for others

We could work out anything
The certificate is signed until 2020 and there is Jo problem with any other computer or phone
I did find out that the connection is completely random
Sometimes the certificate will show up and I'll be able to connect, and some other it won't show up and I would not be able to connect
