I'm using a Raspberry Pi model B with Raspian Debian Wheezy and a Edimax wifi usb dongle. Very often all 'web' traffic stops working on my RPI. I can ssh into it, DNS works, ping works, but curl'ing or wget from my RPI does not. Other devices on the same network don't have any problems.

I've already changed power adapters to a 2.1A adapter. I've looked at dmesg, kernel.log and syslog for anything network-related and found nothing.

Thanks in advance for any help!

Here's example output:

pi@raspberrypi ~ $ curl -v http://www.google.com/

  • @user12321 I did pinging Google, it worked fine. I can ping any site successfully. – Ryan Doherty Aug 5 '14 at 15:14
