Question about which wifi driver I'm using?
 

I'm running Ubuntu 8.10. This version of Ubuntu has the Realtek 8187 wifi dongle driver but my wifi dongle takes the RTL 8187B driver, so I tried installing it's Win98 driver using ndiswrapper. What command would I use to determine if I'm using the ndiswrapper driver or the old 8187 one? If I'm using the old 8187 one, how do I make the change? Thanks.

sudo lsmod or just lsmod and you will see it or type sudo dmesg and see which driver it uses.
lsmod if it shows ndiswrapper and the windows driver then read your man ndiswrapper and learn to uninstall it. not ndiswrapper just the use of the inf file.
most likely the native kernel is being used because the upgrade has it in the kernel it is loaded first unless you told it not to.
