5 packets transmitted, 0 received, +5 errors, 100% packet loss, time 4002ms
pipe 4

Also because of this I suppose I cannot access internet in firefox.

I don't know what is the problem as default route is there.

When I did not add line
DNS1=192.168.1.1, I could ping 192.168.1.1 but after addition of that of that line I cannot.

Either way I get heaps of errors and cannot access internet and this is the problem statement.

Any ideas to resolve ?

netstat -nr is the command !
Thanks anyway I got resolution myself. I tried another adapter in Virtualbox in Bridged network and it worked beautifully.
