Wireless not working in Ubuntu 12.04

[acsoaring]

Ok, so here is my odessy... I have a Cisco AM10 that works fine if the machine is also connected by a hard wired connection, and not at all if the wireless is the only network connection.

By working fine, I mean it shows up on the desktop and connects to my wireless network (can tell it was successful from the router).

I took no special steps to get the adapter working. The attached are the previously requested commands from the PC when it is booted without the hard link (so non-working). My guess is that some change in the start-up process will solve this problem.

And here is what the same commands give me when I boot with a hard wire plugged in: (Note I have to do a "sudo ifdown eth0" to avoid confusing the network)

Hi, please do:

echo "options rt2800usb  nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800usb.conf
sudo modprobe -rfv rt2800usb
sudo modprobe -v rt2800usb

Then:

gksudo gedit /etc/pm/power.d/wireless

(this will create or edit a configuration file that will override the default powermanagement behavior) and enter the following:
#!/bin/sh

/sbin/iwconfig wlan0 power off

above exit0, then save gedit, close and reboot.

If wireless still does not connect copy and paste this command in the terminal (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/netscript.sh && chmod +x netscript.sh && ./netscript.sh

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks

[AC_Soaring]

Thank you. No luck after the modprobe and power changes. I'm getting a 404 error from dropbox while trying to download the script.

[wildmanne39]

Hi,try it this way I changed the name last night sorry! Copy and paste this command in the terminal (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks

[AC_Soaring]

Ok, so here is the upload with a working wireless adapter (booted with the hard wire plugged in and did a sudo ifdown eth0).

I'll send along the non-working version in a minute.

- Alan

[AC_Soaring]

Here is what I get from the same script after booting without the hard line installed (wireless will not come up).

Thank you,

Alan

[wildmanne39]

Hi, did you delete the old text info before you ran the script because I think you posted the old netinfo.text file, power management is still on is the reason I think this and if you did not delete the old file then the new one should have a 1 in the name.
Thanks

[AC_Soaring]

Both the files I posted were new. I renamed the file between runs. The contents of etc/pm/power.d/wireless follow (though they seem to have been ignored...):

alan@ubuntu-64-FX6800:/etc/pm/power.d$ cat wireless
#!/bin/sh
/sbin/iwconfig wlan0 power off

Hi go into this file and add exit 0 to the very bottom the save, close and reboot.
Thanks
