Hi, please change your router settings from tkip to wpa2
then please do

Code:

sudo modprobe -rf rt2800pci
 sudo modprobe rt2800pci nohwcrypt=1

this is good to the first boot..so try it...if it improves then
do..

Code:

echo options rt2800pci nohwcrypt=1 | sudo tee -a /etc/modprobe.d/rt2800pci.conf

Does this matter if I will be connected to my college's network? As I will not have access to change the router setting.

Thank you.

I'm connected to my College's wifi connection. The signal strength on Ubuntu is terrible. My other devices connected to the network receives full strength.

My wireless information is pasted in the following link : http://paste.ubuntu.com/12215647/

Thank you for the support!

I would try disabling IPv6 first.

Deactivate IPv6 support:

Code:

$ sudo su
# echo "#disable ipv6" >> /etc/sysctl.conf
# echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
# echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
# echo "net.ipv6.conf.lo.disable_ipv6 = 1" >> /etc/sysctl.conf
