After trawling through the internet, on forums, support websites, and through dozens upon dozens of answered questions on this site, I've not found a solution to what seems like a fairly regular problem...
I cannot connect to a wireless network, and am continually asked for the network password.
I have tried countless suggested solutions on the different locations I've already referred to. None of them have worked.
Details of my experience are as follows:
I have just recently installed Ubuntu 12.04.1 (32-bit). Ubuntu
installed on my system seemingly fine, and I even formatted my hard
drive during the process. It's as if it were a new desktop computer.
During the installation I was asked to connect to a Wireless Network.
I have a USB Wireless Card connected which I have used to connect
desktop PC's, laptops, and a Wii to the internet from approximately
the same area of the house (thus the same distance from the Wireless
Router). I chose my network, entered the correct password for it (I
double checked; it's definitely the right password) and proceeded with
the installation. Several times before the installation was complete,
I was asked to authenticate the connection, and this seemed to do
nothing each time. On the repeated screens the password was already
entered in the appropriate box.
When Ubuntu booted up the first thing I was faced with (other than
something about Language settings, or something) was another request
for authentication. Again, the password was already there, so I
clicked connect. It did not connect. Instead, I was once again faced
with repeated requests every few minutes.
I went onto my laptop, which is connected to this network, checked the
details of the network, and entered them manually into my Ubuntu PC
(including the IPv4 and IPv6 information) but this didn't work either,
so I set it back to finding the settings automatically. Note, also,
that the "Connect automatically" and "Available to all users" boxes
are checked, and have been unchecked & rechecked countless times. I
have also tried having my User account connect automatically, and to
need a password entered at the welcome screen.
Whilst I've been writing this, it has gone through a spat of
connecting successfully to the network for less than a minute, before
coming offline again, only to repeat the process. But it has now
returned to prompting me for a password every couple of minutes.
This computer has already run on the Fedora OS, and had no trouble
connecting to, and maintaining a connection. I also have a laptop
running Windows 7 less than a metre away from this desktop PC, which
is connected and has no trouble maintaining a connection at 50%-100%
strength (fluctuating).
Therefore:
- I know it's not the wireless card
- I know it's not the PC itself
- I know it's not the access point
- I know it's not the location of my PC or wireless card
- It is solely because of Ubuntu
Everything else has worked fine, but the moment Ubuntu was introduced
into the equation, it has gone completely wrong. Honestly; I prefer
Ubuntu as an OS to Fedora, but if I can't solve the problem it'll be
straight back to Fedora that I'll have to go.
Can anyone help me at all?
