Internet stops working after a few minutes (13.04)

Seemingly at random, my internet stops working on Ubuntu 13.04. Specifically, wired and wireless show as connected, but I cannot reach any page using any web browser or get a ping response.

I can sometimes get a few minutes of internet access when I reboot, although whether or not this happens also appears to be at random. It always disappears, although still shows as being connected, after no more than 5 minutes though.

I've isolated the problem to Ubuntu itself:

No issue on Windows 7

Issue persists on Unity, Cinnamon desktop, Gnome desktop

Issue persists with multiple networks

I've also tried sudo dhclient wlan0 as recommended in a similar thread, with no luck after rebooting.

I'm unsure of what the issue could be, because it worked previously with no issues on 12.10 and 13.04, and I can't isolate any action that caused it.

If anybody has any ideas, I'd be very grateful.

If you're satisfied with a wired connection, turn off wireless, unplug the network cable and plug it back in when the notification icon reads that you are disconnected.

I don't know why both don't work at the same time in the 3.8 kernels, but this works for me on my Lenovo laptop.

Follow up: 14 June 2013 - I re-enabled WIFI and unplugged my network cable. So far it's working fine.

Having the two on together seems to be the issue in the 3.8 kernels. I still have a 3.5 kernel that doesn't have any problem running both simultaneously.
