Wi-Fi rt73 USB (TP-Link TL-WN321G) doesn't connect

I confirm that after i boot from live cd , my usb wireless adapter (tl-wn321g) show the wireless network and can connect perfectly so I install ubuntu gusty beta. I found it works.

After that i just install ubuntu again on same computer but it doesn't work. It ( tl-wn321g) cannot scan the wireless network ( it not show wireless network) it show "no scan results" when i type "sudo iwlist wlan0 scanning"

when I was tty1. I try to plug out and plug in , when I plug it in there is a meesage "phy2 -> rt2500usb_enable_radio : Error - Register initialization failed"

and then I plug out and plug in again "phy2" change to "phy3"

My Belkin rt73 usb stick worked fine (out of the box) for a good while (in Gutsy tribe) until 3-4 weeks ago, now no longer works. The 'Wireless connection' still appears in NM with the correct settings, but the device does not even blink.

Another confirmation comment. From livecd ( 7.10 x86 ) I was able to scan wireless networks, after installing on the computer it can't enable wireless with message 'phy2 -> rt2500usb_enable_radio: Error - Register initialization failed'

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description does not yet have enough information.

1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at [WWW] http://wiki.ubuntu.com/KernelTeamBugPolicies. Thanks in advance!

Well problem is I had this bug and I tried various fixes. In the end I think it is something to do with the wireless config not the kernel. For me this bug was fixed by chance.

I had it that if I used the live cd then I'd get a connection but if I installed then I could not connect.

In fact by chance when I tried to install again my internet connection went down part way through the install. I rebooted into my new system and it all works and has done for a couple of days and through several reboots.

I suggest that if anyone with some expertise wants to ask for particular conf files etc I will provide them and we can see why mine now works.

Hope I can be of some help.

If it is helpful this is what is going on for me.

Note that the modules rt73usb and rt2500usb should not *both* be loading. Try removing both modules, and then loading *only* rt73usb:

sudo rmmod rt73usb rt2500usb
sudo modprobe rt73usb

If that works for you, you can then add rt2500usb to /etc/modprobe.d/blacklist to ensure it doesn't load in future.

I have the TL-WN321G and Ubuntu Gutsy (2.6.22-14-generic), and for me this fix works temporarily. After some time (sometimes a few minutes sometimes more than an hour) the interface stops working and cannot be raised again without a reboot.

I will post some error messages later.

Since I started this...

This is solved for me now...
