I think you're on the right track aus9. For the boots where the wifi scan launches there are dmesg messages related to ipw2200 extension and no dmesg messages referencing eth0. The opposite is true when the scan doesn't launch. I am booting with the nodhcp bootcode.

And no, I don't know how to determine what the wired module is.

'lsmod' should show it, while it's loaded.

Errgh, false alarm. On the last boot there were ext0 messages AND ipw2200 messages, and the wireless scanned and connected successfully. Still looks like the ipw2200 messages don't appear when the scan doesn't happen. I'll keep investigating.

I am your local village idiot and anal too.

for one reboot, don't use that bootcode and don't load any wireless.

as tinypoodle says run
Code: [Select]
lsmod > /home/tc/mylsmod.txt
reboot with your bootcode and wireless stuff and post that txt file so we can read it, then we know what your eth module is, and I prefer you blacklist it and not use nodhcp if possible.

Of course I could be wrong, but I am trying to minimise interference, you decide if its too much hassle etc

Only difference I could spot is that (only) in second case you have lib80211_crypt_ccmp loaded.

I regard tinypoodle as the wireless guru here, but if you happy to try it to see if there in an improvement change your bootcode to

blacklist tg3
  with out nodhcp and see what happens?

I think dmesg should show the firmware being loaded

check for   ipw2200-fw

Is that blacklist tg3 or blacklist=tg3? I tried the latter already and the wireless didn't scan.

I'll check on the ipw2200-fw message.

If it's not some sort of conflict, still wondering if it might be a timing issue or maybe related to the order the extensions are loaded in. Since wireless works sometimes it looks like all the pieces are there. They just don't always get loaded/started like they should. Once it connects I haven't had a drop either which makes me think the hardware's OK.

my bad

blacklist=tg3

I don't have your hardware but tried
Code: [Select]
tce-load -i wireless-3.0.21-tinycore
/etc/sysconfig/tcedir/optional/wireless-3.0.21-tinycore.tcz: OK

Code: [Select]
sudo /sbin/modprobe ipw2200 libipw  cfg80211 lib80211
modprobe: can't load module ipw2200 (kernel.tclocal/drivers/net/wireless/ipw2x00/ipw2200.ko.gz): unknown symbol in module, or unknown parameter
tc@box:~$ sudo /sbin/modprobe libipw  cfg80211 lib80211
tc@box:~$ lsmod
Module                  Size  Used by    Tainted: P 
libipw                 24576  0
cfg80211               94208  1 libipw
lib80211               12288  1 libipw

now try loading ipw2200....yes!
Code: [Select]
tc@box:~$ lsmod
Module                  Size  Used by    Tainted: P 
ipw2200               106496  0
libipw                 24576  1 ipw2200
cfg80211               94208  2 ipw2200,libipw
lib80211               12288  2 ipw2200,libipw

now to reboot and try a shorter list
EDIT  bootlocal now shorter after test

/sbin/modprobe libipw  ipw2200

############

that only leaves the firmware you need to add to onboot.lst
firmware-ipw2200.tcz

but I won't attempt to load it being a scaredy cat  aka the local village idiot

tg3 is the Broadcom Ethernet driver (an updated driver extension is available). As long as an Ethernet cable is not connected i think blacklisting the module should have little effect.

There is a firmware extension available for the ipw2200, load it and advice please so we can update the wiki.  Afaik the ipw2200 requires both driver and firmware to function

Added blacklist=tg3 to bootcodes and (per appbrowser info) put ipw2100 and ipw2200 extensions ahead of other firmware extensions in onboot.lst. So far wifi starts and scans successfully. Will test more thoroughly over the weekend. Thanks for the help.

sorry to be anal, but I am not sure these exist

ipw2100 and ipw2200 extensions

maybe you meant wireless-3.0.21-tinycore.tcz which has the module
/usr/local/lib/modules/3.0.21-tinycore/kernel/drivers/net/wireless/ipw2x00/ipw2200.ko.gz
