Browser unable to load even though Wifi is connected

[thfe456]

Hi, I am a RPi newbie, just learnt how to use RPi.

I am using wifi dongle to connect to my university internet on my RPi. In RPi desktop it shows the blue wifi icon.
But when i get into the browser and search something, the browser never loads.

When I hover my mouse over the blue wifi icon, it shows:

wlan0: Associated with studentlab(P03-telekomlab)
wlan0: Configured 10.61.65.199/22
eth0: Link is down

This is my content in the /etc/network/interfaces:

Code: Select all

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet manual

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

auto wlan1
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

My RPi is in Wheezy version. If you need more information to know what my problem is and want to help me, do let me know.
Your help is greatly appreciated. Thanks!
