WiFi can connect to Intranet but not Internet
Posted: Thu Mar 01, 2012 10:53 am
Greetings,
I have an issue with my WiFi while at work. This laptop works 100% correctly while at home on my WPA2 Personal encrypted WiFi. Work has a guest WiFi for visitors and personal computers. It is WPA2 Personal encrypted using DHCP. The laptop connects just fine and I can see the network and I can even browse any shares from other computers on the guest network. However, I cannot route out to the Internet to save my life. The main IT guy doesn't know what the issue is (I'm IT but I'm working on a different contract for the company). According to him the guest WiFi isn't blocking anything.
The laptop is a Samsung running an AMD A6-3400M fusion chip. I am running Mint 12 KDE. Below is the mintWiFi.py output. When the script queries the DHCP server it breaks something because nslookup stops working after I run mintWiFi.py. So nslookup does actually function. Again I just can't route anywhere. I haven't made any modifications to anything. So I'm at a loss now. Any help would be greatly appreciated.

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
