Well the below part is an edit : I did change the dns to 8.8.8.8 , 8.8.4.4 (i hope that's default google). restarted my browser and undid and did my connections again.
below is a new screenshot of ping google/ubuntu and apt-get update yesterday it was bit different. But i'm still facing issues while opening tabs in firefox.
--> since i'm coming from windows i thought restarting my system (post above update and changes) may work but it didn't. Any other suggestions ?
update: i've googled and read varios forums but not getting any help ! Do we really have experts looking at the site ??!
