[SOLVED] Upgraded, now I have no network or KDE.

cjdj · 2011-08-14 03:53:15

I did a system update on my asus 1015pem (64bit). I've checked other threads about kernel 3.0 upgrade problems but haven't found one that applies.

I've always used Wicd to manage my network interfaces.
wicd does not see any wireless devices.

I can't see any modules being blocked.

My wired chip is AR8132
My wireless chip is BCM4313

Typing this on my tablet, sorry for being brief.
Can anyone point me in the right direction?

In regards to KDE not starting up. I created a new user account, and that starts up ok, so obviously there is a problem with some settings or application in my existing account.

Thats night quite as big a problem as my wireless networking not working, though, so I'll ignore that for now.

Wired networking is working, which is good. But I definitely need wireless working.

Well, start with ip link to see if the card really does. or does not exist.
Second, look through dmesg after boot for comments or errors regarding your networks
Third, look at the loaded modules using lsmod
If the modules for the NICs are missing, try to (as root) modprobe the missing modules.

Post the vendor/product codes from lspci -nn (That is two n's, not m) for your NICs (Those are the two 16 bit hex digits separated by : ) example [8086:1234]

Ip link gives me (i'm currently connected through the wired adapter):

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether bc:ae:c5:d3:0b:ef brd ff:ff:ff:ff:ff:ff

I dont see anything interesting in dmesg.

I've searched the /lib directory for anything bcm and got this:

[root@myhost cjw2]# alias fl='find . -type f'
[root@myhost cjw2]# cd /lib
[root@myhost lib]# fl|grep bcm

lsmod | grep bcm now gives me:

Still dont have wireless. I might add bcm_wimax to the MODULES list in rc.conf and then reboot and see if it works.

cjdj · 2011-08-14 04:59:10

Bluetooth is working, which is interesting, because bluetooth is supposed to be using the same device as the wireless network (from what I understand).

You may want to try modprobe -l instead. It's easier

Still working on digesting your output...

ewaller · 2011-08-14 05:11:08

Do you have a driver called brcmsmac ??
I think that is the winner.

cjdj · 2011-08-14 05:42:00

Thanks for helping me. I did just try the brcmsmac module, and it is at least attempting to scan the wireless networks, but it is not working

EDIT: actually I'm not sure its scanning now either. I think wicd just got stuck once. The module is loaded, but no wireless connections.

I'm not sure I understand what that means. Does it mean that it does not show up in ip link, or does it mean that wicd does not find an access points. If the former, I have to think about it some more. If the latter, then can you post the output of iwlist scan

cjdj · 2011-08-14 07:01:51

The module is loaded

$ lsmod|grep brcmsmac
brcmsmac              594624  0 
brcmutil                6563  1 brcmsmac
mac80211              215605  1 brcmsmac
cfg80211              160516  2 brcmsmac,mac80211
crc_ccitt               1331  1 brcmsmac

But iwlist scan is not showing the wireless interface.

$ iwlist scan
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

wicd-cli is not finding anything.

$ wicd-cli --wireless -S
$

There doesn't seem to be a wlan0 interface at all.

I do have the eeepc acpi event stuff installed, which has tools to activate and deactivate wireless, which seems to be working, but is not doing anything. Wireless was obviously working before the update. The access points are working fine, as I was using my phone and tablet to access this forum before I hooked it up to a wired port.

jasonwryan · 2011-08-14 07:04:11

Have you seen this?
https://wiki.archlinux.org/index.php/Br … rcmsmac.29

cjdj · 2011-08-14 07:23:20

I hadn't seen that, and that's exactly what the problem was. THANKYOU to both of you.

cjdj · 2011-08-14 08:30:40

To anyone else who is also having problems with KDE, I got it working again by deleting the ~/.kde4/share/config/plasm* files.

bernarcher · 2011-08-14 10:26:43

Glad to see it is now working for you. Will you please mark this thread as SOLVED, then.

You're right. I didn't think of doing it that way, because I use my little 'fl' alias all the time for searching for files.
Thanks for the tip.
