Prestigio PSP5457DUO Android 4.2.2 does not connect to my academic network In my university, I have a free internet WiFi access with eduroam system. However (double-checked the login and password already) I can not connect to the network with my phone :( 

All the security parameters are fine (my Asus laptop connects with no problem).

When I had a Samsung phone, I was able to connect. I had to sell it, and now ended up with Prestigio. However, I can connect with other WiFi networks around using my phone. What might be the problem here?
This is something you should ask the IT support people at your university about. Most mysterious problems like this are caused by security settings on the Wi-Fi network itself. Probably it is MAC-filtered, so only devices that have been registered with the network administrators are able to connect. You might have forgotten registering your previous phone if you've had it for a long time.
