Internet is not working in RPI

[privatejava]

Hi,
Today I have successfully configured for making wifi hotspot using the internet from Ethernet by the help of some sites. But I am amazed that I am now not able to use internet in my Raspberry pi however the internet is working totally great for users from hotspot wifi's user.

Please help.

So there's the problem. You don't have a resolver defined in /etc/resolv.conf.

Change it to

Code: Select all

nameserver 201.94.65.2 
nameserver 201.94.65.3
nameserver 8.8.8.8

Well, there's your problem! You've got nothing configured in /etc/resolv.conf, so your Pi can only access hosts by IP address and can't access them by name using DNS. Try copying your name-server settings from /etc/network/interfaces into /etc/resolv.conf i.e.

Code: Select all

nameserver 201.94.65.2
nameserver 201.94.65.3

EDIT: LOL, beaten by Dougie!

Wow it worked !! Last time i added but again commented them out due to some reason. Thanks for saving my time and I am so amazed with the fastest reply ever. This was my first forum post in raspberry pi ...!! Thanks again

Is there something like rating that i can give you guys?

I'll just take the kudos of beating Andrew.
