It worked fine for a few days, then there were a few days where it started having problems sometimes and working sometimes. Now it never works at all.
I have 5+ devices all able to connect without any trouble at all, including iPhone, Android phone, 3DS, multiple game consoles, a laptop running windows 7, and even a second desktop machine running Ubuntu 12.04 sitting right behind the 13.04 machine. All other devices have full wireless bars displayed (strong signals).
At any moment, one of the following is happening, and it changes randomly:
Trying to connect forever, but never establishing a connection.Wireless icon constantly animating.
Finds no wireless networks at all. (There are 12+ in range according to other devices.)
Will not try to connect to the network. If I use the icon to connect, it willdisplay 'Disconnected' within a few seconds.
Will continuously ask for the network password. Typing it in correctly does not help.
Wireless is working fine. This happens sometimes. It can work for days at a time, or only 10 mins at a time.
Various things that usually do nothing but sometimes fix the problem:
Reboot. This has the best chance of helping, but it usually takes 5+ times.
Disable/re-enable Wi-Fi using the wireless icon.
Disable/re-enable Networking using the wireless icon.
Use the icon to try and connect to a network (if found).
Use the icon to open Edit Connections and delete my connection info, causing it to be recreated (once it's actually found again).
Various things that seem to make no difference:
Changing between using Linux headers in grub at bootup, between 3.10.0, 3.9.0, or 3.8.0.
Move the wireless router very close to the desktop.
Running sudo rfkill unblock all (I dunno what this is supposed to do.)
I've used Ubuntu for 6 years and I've never had a problem with networking. Now I'm spending all my time reading through endless problem reports and trying all the answers. None of them have helped. I am doing this instead of getting work done, which is defeating the whole purpose of using Ubuntu. It's heartbreaking to be honest.
In the current state of 'no networks are showing up', here are outputs from the random things that other people are usually asked to run:
lspic
lsmod
sudo lshw -c network
sudo iwconfig
sudo iwlist scan
NOTE: This dmesg was done after a reboot where the network manager was continuously displaying the 'disconnected' message over and over. So it must have been trying to connect at this time. My network was displayed in the list of options, as the only option despite other devices picking up 12+ access points. The router channel is set to auto.
dmesg | tail -30
The router uses MAC filtering, and security is WPA PSK with cipher as auto.
So, any ideas? Or is the solution just to not use 13.04 unless you have a wired connection? (I don't have this option.) If so, please just tell me straight. I survived 9.04 Jaunty, and I can survive 13.04 Raring.
Update #1
Results from trying Wild Man's first answer:
I tried:
but I didn't have the package. It said to install gksu. I tried that, but of course, not having Internet, I didn't get the package.
So instead I did:
Which created the file. Here is the body:
I then rebooted. No change. I tried adding exit 0 to the bottom of the wireless file, and rebooted. No change. Please note that this is a desktop machine. I'm assuming power management is primarily for laptops, but the iwconfig does state that power management is on, so who knows.
The recommended router changes I did not do, since the current router settings are (I think) required for some of the older devices I have, and because the current settings work on all my modern devices including Ubuntu 12.04 and Windows 7. I do appreciate the advice though, and I'll look into it when I have time.
Anything else to try?
Update #2
I booted into Ubuntu 12.04.3 from a dvd, and the same problems exist.
I have a separate old desktop machine with 12.04 installed that has no wireless problems at all. So obviously the problem is wireless hardware compatibility in both 12.04.03 LTS and 13.04.
Update #3
The same problems exist even when using a wired connection. I plugged an ethernet cable directly to the router and the network manager added an 'Auto Ethernet' entry, but it cannot establish a connection to it. So the problem is not specific to wireless.
Meanwhile, I purchased a Trendnet N300 wireless USB adapter, TEW-664UB. I plugged it in, but I have no idea how to get Ubuntu to try and use it. Can anyone tell me how? Can I download a package on another computer and copy the .deb over to do an install, etc?
I'm installing windows 7 to double check that the internet connection works there and it's not just some magically faulty hardware.

watch for errors.Then:
(this will create or edit a configuration file that will override the default power management behavior) and enter the following:
above exit0, then save gedit, close.
This error message is in dmesg 'disabling HT as WMM/QoS is not supported by the AP' I recommend going into your router and changing that to disabled.
Also set your encryption while in the router settings to wpa2 only if you have that option.
If you change encryption to wpa2 you will need to go into network manger in the top right corner of the screen by clicking on the internet icon, then go to edit connections>wireless and change security settings to wpa/wpa2 and reboot.Thanks
