Networking anomalies

Just downloaded and giving a test spin on the latest VSIDO 64bit livecd.
I will give my good impressions on another thread another time.

 I seem to go through this initial setup issue/protocol with my wifi 5100ANG  in all SID circumstances (including Siduction/aptosid/semplice etc)
 These circumstances exist on each LiveCD boot and on the initial HD install. Once I follow the below steps on the HD install then I don't have to revisit the steps.

 Here are the circumstances. I would like to know do others encounter this with other wifi cards?
 
  While the needed iwlwifi module is loaded by VSIDO on boot and the ifconfig
  brings up the wlan0 device My wifi is not actually lighted nor am I able to make a CENI connection to the router.
 
  My solution seem to be to back out In Order the involved modules and bring down the wlan0 device. Then modprobe In Order all supporting modules and the iwlwifi module then
  ifconfig wlan0 up
  and Bingo I am in business and I can use CENI to connect.
  Comments appreciated, My terminal steps below...
 
  Start off by displaying the wlan0 desposition at boot to Desktop.
 
Code: [Select]
wlan0     Link encap:Ethernet  HWaddr 00:24:e6:00:3b:62 
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
Next here are the pertinent modules

Code: [Select]
vsido@vsido:~$ lsmod | grep wl*
iwldvm                111887  0
mac80211              386825  1 iwldvm
iwlwifi                73248  1 iwldvm
cfg80211              366201  3 iwlwifi,mac80211,iwldvm
cpufreq_powersave      12454  0
firewire_sbp2          17956  0
firewire_core          49206  1 firewire_sbp2
crc_itu_t              12347  1 firewire_core
iTCO_wdt               12831  0
snd_hwdep              13189  1 snd_hda_codec
iTCO_vendor_support    12704  1 iTCO_wdt
wmi                    13243  0
snd                    53077  10 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_seq,snd_hda_codec,snd_hda_intel,thinkpad_acpi,snd_seq_device
serio_raw              12940  0
scsi_mod              158517  5 sg,libata,sd_mod,sr_mod,firewire_sbp2
Now Remove the modules

Code: [Select]
:~$ sudo modprobe -r iwldvm
:~$ sudo modprobe -r mac80211
:~$ sudo modprobe -r iwlwifi
:~$ sudo ifconfig wlan0 down
Then load them back in In Order

Code: [Select]
:~$ sudo modprobe -r iwlwifi
:~$ sudo modprobe -r mac80211
:~$ sudo modprobe -r iwldvm
:~$ sudo ifconfig wlan0 up

Lights UP and on to CENI

I don't have this problem when the iwlwifi is preloaded with non-SID distros.

That is odd. Ive got SID installed on a number of different systems with all different hardware and havent seen that particular issue. Thanks for posting how you fixed it, im sure somebody will need it at some point  :)

 Yeah, more of a work around.
Unloading the Network Device then the modules and reloading them.

Seems SID can't activate the 5100AGN wifi at initial boot.
I make sure that (when I want to install a SID on this SL410 Lenovo Thinkpad ) I have the the Wifi 5100AGN activated by the post's steps First. Then I install to HD or USB and I have an Activated Intel 5100AGN working at boot.

I have a few other SID liveCD issues with various hardware that I will post also.. seems to be particular to this Hardware. I also have an Inspiron 14z which has the 5100AGN which displays the same issues.
