New Problem
I am now able to access the internet but, when I connect to netgear router NO data is recieved and I can't also ping my router.This does not happen with any other router like DLINK or my phone's HOTSPOT. PLEASE can anyone help where the problem is.
The below problem is solved.
I have Sony vaio laptop having installed Ubuntu 14.04 on it. Laptop can connect to the wifi router but when browser is opened I get the Web page is not available
error.
I did
$ ping google.com
ping: unknown host google.com
I ping my laptop. That returned success. But when I ping some other IPs it says destination host unavailable
This error started since I hard reset my router

$ lspi -knn | grep Net -A2
02:00.0 Network controller [0280] : Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01)
Subsystem : Foxconn Interntional , Inc Device [105b: e044]
kernel driver in use : ath9k
I think I have messed up some thing because of trying too many solution. Is there any way like we have factory reset
in mobile phones...so that I can be able to start again.
One thing I can
ping 8.8.8.8
with 100% success

This is what I tried on terminal
sudo lshw -c network
ifconfig
sudo service network-manager restart
sudo service networking restart
sudo /etc/ini.d/networking restart
sudo ifconfig wlan0 down
sudo service networking restart
sudo /etc/init.d/networking restart
sudo ifconfig wlan0 down
sudo ifconfig wlan0 up
sudo apt-get remove --purge resolvconf
sudo dpkg --configure -a
lspci -knn | grep Net -A2
lsb_release -rcd ; uname -r;
lspci -nnk | grep -iA2 net
lsmod rfkill list all nmcli nm status
nmcli nm enabled true
echo 'options ath9k nohwcrypt=1' sudo tee /etc/modprobe.d/ath9k.conf
rfkill list
Output of route -vn

The command ping 192.168.1.1
does not give anything! After some time I press Ctrl+C and all this gives me 100% data loss.
How should I proceed?
