DWA-552 won't access internet

[pseudonyma]

It looks like ndiswrapper isn't completely gone:

find . -type f -exec grep -l 'ndiswrapper' {} \;
./sysconfig/network/scripts/ifup-wireless
./udev/rules.d/70-persistent-net.rules

How do I rid myself of ndiswrapper?

The following commands don't produce any output:

find . -type f -exec grep -l 'ath0' {} \;
find . -type f -exec grep -l 'wifi0' {} \;

But this does:

find . -type f -exec grep -l 'wlan0' {} \;
./rules.d/70-persistent-net.rules

I'm not sure what to do with this information.

I can connect to a wired network using SuSE, and Windows connects to the network wirelessly, so I think the network's configured correctly. What am I missing?

Thanks for your help.

I still haven't been able to figure out how to get my computer to connect to the internet, and I'm not really sure what to do next. I'm pretty new to "looking under the hood" of my Linux system, so if anyone could do a little hand holding and tell me what to do next--even if it seems really obvious--I would be very grateful.

Sorry to be a bother, and thank you for your time,
Caleb
