Ubuntu finds no wireless internet

Do you have the same message when you do:

dmesg | grep 286

If so, did you try the fix above?

May I see, from 64-bit:

lspci -nn
lsmod | grep rt2

Thanks.

I test 64 bit from a live CD. I'll have to wait until later to run those commands and post the results. Thanks for taking an interest in this problem!

Man, oh man! That is sure a lot of driver modules fighting for control of one poor little wireless device. Let's kick some out and see if we get better performance. Please do:

sudo gedit /etc/modprobe.d/blacklist.conf

Please add four lines at the end:

blacklist rt2800pci
blacklist rt2800lib
blacklist rt2x00pci
blacklist rt2x00lib

Proofread carefully, save and close gedit.

Reboot and let us hear your report.

and this would work on a live CD? The reason I ask is that I don't have 64 bit installed. I run 32 bit well and just test 64 bit. This wireless problem has intrigued me. Well, let's see what happens . . .

[chili555]

and this would work on a live CD?

It won't work if you reboot. Instead, simply remove all of the rt2800 and rt2x00 modules:

sudo rmmod -f rt2800pci
etc.

Remove all of them instead of blacklisting. Check to see if they're all gone except rt2860sta with:

lsmod | grep rt2

[chili555]

If your wireless device is USB, you could remove it, then rmmod all the drivers, write the blacklist file changes and then reinsert the device. It ought to work perfectly.

I've got a pcmcia card in my Dell Inspiron 1000 that is also acting up. It was working in 10.10, but I decided to wipe it and downgrade to 10.04. So I burned a CD of 10.04 and did a fresh install. Now my wireless card (which used to work) no longer works. Card itself is powered up. It is a Netgear WN511B. It uses a Broadcom BC43XG Rev 01 chip.

Is there any solution that doesn't involve a network cable? I'm broke and don't want to buy one.

Thanks for the help!!

Please start a new thread. I'll try to catch it right away, but PM me if I don't answer right away. With the card plugged in, please post:

lspcmcia -v

Thanks.
