I've got Ubuntu 13.10. It has been giving me problems with Firefox for a while by freezing a lot. Tonight something different is going on. I can use WiFi for a while and it just turns off. The graphic on the menu bar shows that I'm connected but no web browser will open. If I then click the icon it will show the name of the network. When I click that network name it will begin to show the graphic that it is trying to connect. In a few moments it will give me the message that the computer is disconnected. I have another computer beside it and it remains connected. What is going on? How can I fix it?
If I restart the machine it will work with the WiFi for about five minutes and then it quits. I have done this about five times with the same results every time.
The computer continues to work just fine. I can play movies and open files. I just can't connect to the internet using WiFi. I am too far away from the modem to connect using an ethernet cable. This is a big desktop with a big monitor attached to it.
Do you think that the constant crashing of Firefox is also related to this problem? The whole machine would freeze when that happened. Ubuntu 13.04 was really great. It froze only a few times in many months. I really don't want to download the 13.10 iso again but I might have to reinstall it from a fresh file. I did not do that before. I updated it from 13.04 about three or four weeks ago.
This is really a disappointment. Software isn't perfect. I'm learning this lesson a lot lately. With 13.04 I was about ready to give up my 2008 Mac Book and use Ubuntu exclusively. I guess I'm glad I kept it. That is how I'm reaching this forum.
All help is appreciated.
