wireless managing to connect, but internet not working

[brucezepplin]

Hi, I manage to connect the laptop to the wireless (ie shows connected to wifinetwork) however when i try to run something in the browser it just doesn't work. after pinging it shows that I am not connected to the internet, despite the network manager showing that I am. If I press F5 to turn wireless on/off, the internet works as it should, but this can take up to 10 times to restart the wireless before it works. this happens around 10-20 times a day in which the internet will stop working while I am still "connected". Any ideas as to why this is?

this has happened 3 times while I typed this out. strangley, if I am streaming or downloading something this tends not to happen.

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd
