My Macbook 3,1 can connect to my router, but cannot use the connection. I have tried to solve this problem, but not smart enough to do so. That's why I'm turning to you.

How I am able to connect to the internet:

  • On Windows XP through both wifi and ethernet with home router
  • On Mac OSX 10.5 through both wifi and ethernet with home router
  • On Lubuntu 14.04 through ethernet with home router
  • On Lubuntu 14.04 through wifi with school router
  • On Lubuntu 14.04 through unsecured wifi hanging in the neighbourhood

How I am not able to connect to the internet:

  • On Lubuntu 14.04 through wifi with home router

I am able to connect to the router as shown in the picture below, but somehow I can't use the connection. I can't even ping to the router itself, while the laptop is showing up in the DHCP list of connections with the correct MAC address and the same Assigned IP address as you can see in the picture.

I am completely lost at to what the problem might be. Anybody knows where the problem might lay?!

After running the script found here as suggested by Wild Man, I got the following output. See pastebin.

  • Can u connect to your own router if you keep it unlocked? – orestis Aug 02 '14 at 18:09
  • @orestis I disabled both mac filtering and the security and still the same problem... I can connect, but can't ping nor use the internet... I tried my phone and he can connect as usual. – Peter Raeves Aug 02 '14 at 18:14
  • This is a very long shot,but it may have to do with the wifi channels. I had a similar problem with one laptop and I found out that the laptop would work better in the channels in the middle. For a strange reason, both I had to declare the same country in both the router and the laptop in order for the laptop to work when the wifi channel was on the far-end i.e. channels 1,14. You could also try setting your laptop a static address (and set the DNS server to 192.168.0.1). What happens when you use a live CD? – orestis Aug 02 '14 at 18:21
  • @orestis I tried channels 1,2,4,6,7,8 and 10, but no luck. I tried with the live CD, but even after installing the driver, my wireless card isn't showing up in ifconfig, nm-applet, etc... So I can't turn it on to even try. – Peter Raeves Aug 02 '14 at 19:14
