I'm using Ubuntu 12.10, on a TOSHIBA Satellite L755 laptop, and using a Cradlepoint MBR-1000 wireless router.
The wifi supposedly works fine on my sisters' and mom's laptops, and my dad uses a wired connection through the router. Nobody else has the problem.
It shows that I'm connected and everything. The network manager GUI shows that everything is going just dandy… but it's not. I'll be able to load a page or two, then I have to disconnect, and reconnect to the router to get it to work again for a couple minutes. I noticed when I was downstairs, close to the router, this problem seemed to go away (at least, I was connected for a couple of hours without running into this problem).
When I run
ping -n 8.8.8.8
it shows this while the connection is still running fine

I was in network settings, and I noticed "Cloned MAC address" was left blank. At first, I changed the Device MAC address, AND the Cloned MAC address to be the same as the LAN MAC address. I thought this fixed it, because it lasted for about 30 minutes, before giving me the same issue. Although, this time, it gave me an error message that said "MAC address doesn't match (not exact words)". Then, I switched the Device MAC address back to it's original setting, and used that MAC address as the Cloned MAC address. This also seemed to work for a little bit. Then, instead of giving me the error in the terminal when runnging ping -n 8.8.8.8
From 192.168.10.199 icmp_seq=178 Destination Host Unreachable
It just outputs:
ping: sendmsg: Network is unreachable
AND, it shows that it's not connected to wifi anymore. I think I may be on the right track to fixing this. Also, this "Network is unreachable error" may be because my dad turns the router off at night because the LEDs on it are too bright for him to sleep.
