Ubuntu 9.04 update broke wireless?

**waterhead** · 07-08-2009

Nevermind, I'll post the relevant section.

Code:

[   21.407904] iwlagn 0000:0e:00.0: firmware: requesting iwlwifi-5000-1.ucode

I don't see anything wrong. Post the output of these commands.

Code:

ifconfig

Code:

iwconfig

You can manually scan for networks with this command.

Code:

iwlist wlan0 scan

I going to bed!

**waterhead** · 07-08-2009

OK, this is the wireless network interface. It seems to be working, but it doesn't have an IP address.

Code:

wlan0     Link encap:Ethernet  HWaddr 00:22:fb:20:0a:76  
          inet6 addr: fe80::222:fbff:fe20:a76/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:217 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:25101 (25.1 KB)  TX bytes:576 (576.0 B)

You appear to be connected to the "linksys" wireless network. But look at the bit rate and quality level. This is why it drops out.

Code:

wlan0     IEEE 802.11abgn  ESSID:"linksys"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:23:69:5B:91:29   
          Bit Rate=1 Mb/s   Tx-Power=15 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Encryption key:off
          Power Management:off
          Link Quality=12/100  Signal level:-82 dBm  Noise level=-87 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

This is verified by the Quality level of the scanned connection:

Code:

wlan0     Scan completed :
          Cell 01 - Address: 00:23:69:5B:91:29

This connection has a much better quality rating, can you connect to this one?

"HOME01" is my AP.

Well, it appears that it is not connecting to your AP, but another one named "linksys". I would delete all of the saved wireless connections, and then connect to the one you want (HOME01). Right-click the NetworkManager icon and select "Edit Connections". Delete all of the connections under the wireless taab. Then left-click and choose the HOME01 connection to connect to.

If your HOME01 connection is a hidden network, meaning it does not broadcast it's availability, then you need to uncloak it. As you can see, that doesn't really work anyway, but it makes it difficult for NetworkManager to connect to it.

HOME01 is the only connection listed in my Network Manager,
and its setup for Auto connect. Although I have not deleted that
and tried to re-add it yet, I will do that and see what happens.

What I find odd is that my "Enable Wireless" option is grayed out
on the Network Manager icon on the task bar. I did not pay much
attention when it was working, but I would assume it was available
previously. We'll see if the delete/re-add helps.

**waterhead** · 07-08-2009

I assume that by being greyed out, you mean that you also cannot click it to enable it. This is usually caused by there being no usable wireless card, but we know that isn't true. it also can be caused by configuring a different connection manager to handle the wireless connections.

Maybe this is a problem with NetworkManager. You can try using a different connection manager, like Wicd. Wicd can be install through the Synaptic Package Manager, or with Apt. I believe that it will automatically disable NetworkManager

Code:

sudo apt-get install wicd

My wireless is fixed (and I'm on my Ubuntu again right now).

Here's the sequence of events...

I decide to see if I can reinstall the Network Manager first.
I connect via hard wire and reinstall the package
I restart networking
It still does not work

Since I'm online it found updates and asks me about them
I go ahead and install them
As the updates finish, my wireless fires on up!

Looks like it was ANOTHER round of updates that killed my wi-fi.

**waterhead** · 07-09-2009

I learned something when dealing with systems setup with MythTV. When you have it all setup and working, disable any updates. You don't need to fix something that isn't broken.

I do agree with not fixing something that isn't broken, but I also
don't want to miss out on any security related updates (like ssh).
Double edged sword, I guess.

Thanks for your help!

**Hal343** · 07-10-2009

The solution is to not allow automatic updates. When you are alerted of updates, pick the ones you want to use and refuse the rest.
