I am using linux mint julia.
It takes really longtime to get my laptop to connect to wifi when i am using linux mint julia.
We use IEEE 802.1x (WPA2 Enterprise) based encryption for security on IITD_WIFI1, IITD_WIFI2, IITD_WiMAX, and IITD_WIFI3. For authentication, IITD_WIFI1, IITD_WIFI2 and IITD_WiMAX use the EAP method EAP-TTLS with PAP as the inner-tunnel method. This method is natively supported in Mac OS X and Linux. Many versions of Windows also support it natively. IITD_WIFI3 uses the EAP method PEAP with MSCHAPv2 as the inner tunnel method which is supported natively on Windows platforms and is commonly available on mobile phones and other hand-held devices. Use of PEAP/MSCHAPv2 will require registration of password with the Microsoft Active Directory. IITD_Guests is an "Unsecured network" but uses HTTPS authentication based on captive portal technology.
And whenever it does connect it connects to only IITD_WIFI3 and the signal also comes out to be very low around(40-60%). In windows, i dont have a problem connecting to wifi. I am using Lenevo SL500, with network card:
Network: Card-1 Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller driver r8169
Card-2 Atheros AR5001 Wireless Network Adapter driver ath5k
