I'm in desperate need of firmware/extention for a Realtek USB wireless b/g/n adapter.  So far I've really struggled for close on three weeks attempting every trick I can find before inevitably compiling from source.  
At some point I was able to create an ndiswrapper with WinXP drivers on an earlier tinycore build which did at least function reliably, although was a little high on cpu resources unfortunately.   Since then I haven't been able to duplicate the same configuration.  Anyhow the issue with the current ndiswrapper is not being able to connect or stay connected for very long, appears to be a driver/firmware issue.  
Attempted the new wifi extension over the last couple of days, also without any success.  "Fails to get an IP address." then times out.  I don't know if the script flushes the routing tables etc etc post failed connection which leaves you a reboot available to start over.
When booted to a puppy linux distro the wireless adapter functions 100% without any extra work on the same PC.   With the script available here to convert deb files to tcz extensions I grabbed the driver form this distro and attempted to convert it, without any success.
This bring me to a decision point, I think the only reliable method of connection is to compile the correct firmware/driver.  So I grabbed the driver/firmware source for the rtl8192su from
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=falseand installed "compiletc" & "squachfs-tools-4".   The source came with a makefile but no configure file.  
The first hurdle:  running either make or ./make results in  "file not found!!"
any suggestions welcome please?
