Try entering your wireless password permanently.
To do that:
1. Right click your "Network Connections" icon . . . typically that's in the top panel, on the right side, and it can be vertical bars or offset computer screens, depending on your theme. Most often for wireless connections it's a set of vertical bars, but it's really dependent on your theme.
2. A drop down menu will appear, and slide the pointer down to "Edit Connections" and click on it.
3. In the "Network Connections" window that appears, click on the "Wireless" tab.
4. Highlight your connection. When you do that, the "Edit" button should go from grayed out to enabled.
5. Click on the "Edit" button (then a request for your LOG IN password should appear . . . NOT your wireless password).
6. In the window that appears after you enter your log in password, titled "Editing Auto <name of your wireless connection>", click on the"Wireless Security" tab.
7. In the "Password" field, enter your wireless password.
Try it first without checking "Available to all users". Click the "Apply" button. Close the "Network Connections" window, and you're . . . DONE!
Do a restart. Your wireless connection should be detected and you should log in to it without it asking for your password. Give it a little bit of time though . . . maybe 15 seconds.
If that doesn't work, go back in and check "Available to all users" and try it that way and see if it works.
