I am facing extremely slow wireless connection on Ubuntu 14.04. Also the connection is sporadic. Please help me with this. Also, if there is any more information needed do let me know.

I had found the link from @samsy to be useful, and had a couple of additional things that I did which helped, but did not cure, the problem:
WICD does not entirely work for me in 14.04 - the wireless will not automatically connect, and WICD seems to be unmaintained
I had improvement in wirless performance by setting the regulatory agency:
iw reg get
sudo it reg set US
Change your country code as required
Disk scheduling also seems to have helped me. My install defaulted to 'deadline' for a disk scheduler. I've changed to cfq for scheduling, and am much happier with overall performance.
To show scheduler:
for f in /sys/block/sd?/queue/scheduler; do printf "$f is "; cat $f; done
to change scheduler:
echo cfq > /sys/block/sda/queue/scheduler
To change it persistantly, either use the above command in /etc/rc.local, or place it as a kernel option (elevator=cfq) in grub
