[Solved] Wireless not working after upgrade

[kln]

Hi,
I can't get my wireless to work, it seems, since last upgrade to Maverick. Wired connection works fine, with either Wicd or KNM, but wireless won't. No wireless connections are shown, though I know I have two or three strong wireless networks around (public networks with given password)

I have looked a some similar problems, so thinking of a network switch problem, I tried to boot with switch OFF and turning it on after, and booting with switch ON too, rebooting after disconnecting the wired connection. No results. Cf. the result of rfkill below, which looks normal.

At one point - I was copying the output of commands in Konsole - KNM managed to detect the wireless networks (two, both 100%), but I was unable to connect. It didn't happen twice though.

I have looked at the other posts going on right now. Any idea on what I should try before giving up on MM 10.10 ?

UPDATES:
Wireless works fine with the 9.10 Live CD (the interface used is ra0).
I don't keep both KNM and Wicd at the same time.
I used to connect to the same networks with 9.10 and 10.04 in the past.

Many thanks in advance

It looks like the wrong driver is trying to be loaded, you may have to 'blacklist' the offending driver module. Please post the output of :

lsmod | grep rt2
And we can see what needs to be blacklisted (the things listed in the link may incorrect or overkill for your specific card)

[kln]

Here it is :
I'm looking at the thread you've linked to.


$ lsmod | grep rt2

eeprom_93cx6 1789 1 rt2800pci

I've been using RT2860 so far.

[claydoh]

you may have to blacklist the list, though perhaps trying one at a time so you don't loose anything suspend-wise.

[kln]

Except the one that are linked with RT2860 ?
such as the 1st and the 6th one ...
What do you mean suspend-wise ?

Should I try to suspend to RAM each time to check ?

[claydoh]

naw, just start with the first one in the list on the ubuntuforum post, and see if it works after a reboot, and keep adding until it does work. I *think* the rt2860sta may be the one you want to keep, the ones in the forum post I think are causing the conflict.

I have a different rt usb adapter that I actually had to blacklist the sta one (opposite of what everyone else was) in 10.04 - now working fine in 10.10 with no mods

[kln]

Wow, it worked with the first line ... blacklist rt2800pci

So the hint was in the configuration line of the $ sudo lshw -C network command ? "driver=rt2800pci" means the wrong driver was loaded, I take it.

Thank you very much, that was a really fast solving. You guys are really good at spotting the cause of the problems !
I try another two days to check that there are no other problems then will mark the post as solved.

NB : I'm glad not to go back to 10.04 as the upgrade to 10.10 has at last solved the built-in mic problem on my laptop

[kln]

Ok I got the same problem as Castor_fou, it doesn't resume after suspend to RAM. I check the post.

NB : now I got

$ lsmod | grep rt2
rt2860sta 559618 0
crc_ccitt 1699 1 rt2860sta -- which makes sense.

[claydoh]

well, it shows which driver was loaded, wrong or not :)
sometimes one module loads others as well and you had a number of them loaded (from the output of lsmod I gave you) but exactly which one was causing it ??

I suspected the first one in the list, so thats where I had you start :), with others to try if I was wrong.


Anyway glad you are up and running. I wonder if it worth a bug report - there was one for my particular usb stick in 10.04,but i didn't quickly see one for yours in 10.10

[claydoh]

I did find some (https://launchpad.net/ubuntu/+bugs?field.searchtext=rt2860&orderby=-datecreated&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHOUT_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=) but with varying ages Ubuntu versions, but no 100% solutions after a quick glance :(

[kln]

in the thread you've linked (http://ubuntuforums.org/showthread.php?t=1617290&page=2), castor_fou did a BIOS update -- Zepto released one last year (mostly correcting - but not really correcting - an overheating issue) and has gone bankrupt since then >:(
I have no Fn-F2 wireless on/off command and any tricks, like switching on/off the switch and/or wicd, did not show any result.

[kln]

Ok, I checked some of the bugs, but none offer an answer for failing to resume after startup.
$sudo rfkill unblock wifi doesn't work.

I will try more another time. By now, having wireless on startup is already a huge progress! Thanks a lot.

[claydoh]

Actually one thing to try is to actually blacklist the rt2860sta driver as well, forcing the use of the 'normal' rt2860

though you may have to use

sudo modprobe rt2860 if the lsmod | grep rt2 output does not show the rt2860

just a longshot, but it actually worked for me in Lucid

[kln]

$ sudo modprobe rt2860
[sudo] password for :
FATAL: Module rt2860 not found.

So when I blacklist rt2860, nothing is left in lsmod | grep rt2 output, and no driver nor wireless is loaded.

When I installed the driver in April 2009 for the first time (built, installed and added to etc/modules), it was already the STA version, v1.8.0.0

[claydoh]

it was a long
shot :(

[kln]

The problem of wireless not resuming after suspending to RAM doesn't happen anymore. Could be the result of recent updates.

Actually, during a few days, resuming after suspending to RAM wasn't working. Only black screen and pointer, nothing else. Perhaps both problems where solved in the same time.
