Raspberry pi internet connection

My Windows PC connects to the internet via an ethernet cable with no problems but using the same cable with my Raspberry Pi, I cannot connect. The network icon on the desktop appears to show a working connection but if I try to open a browser window, nothing happens.  I've also tried to connect via  the official Raspberry Pi wifi dongle with similar results.  Any suggestions?

Re: Raspberry pi internet connection

What is your wiring layout for the Pi - is it wired directly into the back of your router, or is the wiring more complicated?

Re: Raspberry pi internet connection

On the pi, open a terminal window and type in the following
ifconfig
ping google.co.uk


Then give us the results here, you only need the ip address & gateway settings from ifconfig and whether the ping is successful or fails.

Re: Raspberry pi internet connection

Hi 

Thanks for the answer.  I read on another forum that sometimes reinstalling Raspbian could cure matters.  It did - I can now connect by ethernet.  However I still tried the commands you suggested and he result of Ifconfig was: 

eth0 Link encap:Ethernet HWaddr b8:27:eb:a8:bf:6f
inet addr:192.168.1.7 Bcast:192.168.1.255 Mask:255.255.255.0

RX bytes:16656 (16.2 KiB) TX bytes:16656 (16.2 KiB)

 

And to the ping - 

pi@raspberrypi:~ $ ping google.co.uk
ping: icmp open socket: Operation not permitted

I'm now trying to connect with a wifi dongle (so far unsuccessfully) as I need the ethernet cable for my Windows pc.  

Thanks again

Re: Raspberry pi internet connection

For your ping try entering:

sudo chmod u+s /bin/ping

Then try again with ping.
