Strange, it should automatically be enabled when you click the wireless manager icon. You can tell if it did as the 'active wifi' button will be grayed out. If it isn't, click it. Did it work fine with the default OS before your flashed 3MX? I've never heard of that machine before, but after some googling it seems to be the same as the rest of these machines. I guess we could try a few things....
Open Terminal and type "lsmod | less" (without the quotes) and use the arrow keys to scroll up/down and q to quit back to terminal prompt. Look for zd1211b. That's the wireless driver. If you see it the driver is loaded. If not type "insmod zd1211b" (without quotes) and try the wireless manager again.
If that doesn't work try this..
In terminal type:
echo 1 > /proc/jz/iwifi (turns on the wifi stick)
Rerun wireless manager.
If that doesn't work, maybe try to reflash Ultra 1 more time. Maybe something went haywire on the first installation. It's doubtful but worth a shot.
If that still doesn't work, maybe skytex changed to a different brand of wireless card. In that case you'd have to reinstall your default OS (my alpha400 came with a cd with backup recovery.img on it) and copy the wireless driver to an sd/usb card so you can copy it to Ultra after reinstallation.
Good luck. 
Thanx for the reply Wicknix,
Tried the first thing you suggested and couldn't get the scroll keys to work correctly (it just scrolled through what I had input and put on last line). So then I tried typing insmod zd1211b as suggested and got this response "module zd1211b already present" or something to that effect. I am assuming this means that the module for the wifi driver is in the 3MX Ultra OS as it should be.
Then I typed in command to turn on the wifi stick as suggested. Retried wifi manager.....no go. At this point I figured I had a different card in this machine. I went ahead and loaded 3MX 4 first and tried the wifi...no go. Then reloaded Ultra....no go.
My assumption from this is that everything about the Skytex is compatible with the new OS except for the wireless card. (maybe?). Here is my current position, I guess. I do not have the original OS and this unit did not come with a recovery disc. I thought of using the recovery OS here but obviously the wifi driver for it would not be correct either. To answer your question, yes, the wireless worked fine before reformatting and going to new OS. Although it did seem to have limited range (from reading here I think that is normal).
So, I guess, do you have any idea about a wifi driver(s) I could try in order to get this working again? Is there any way I can use the root access terminal to find out what card is in the machine?
Thanx in advance for your time!
