I installed Ubuntu 12.10 a while ago, and was my first upgrade ever as I upgraded from 10.10 to 12.10. However, ever since I have installed the new version, the wireless connection has been unbelievably slow considering I am getting much less than the other Windows computers at my house. I would like to know how to fix this problem, and if any more info is needed, I will get it. Also, I have noticed that sometimes the network manager doesn't show any networks, and it only gets fixed if I restart the computer. Help me please
