I have a very weird problem. I am running Mandriva 2010.0 on a Lenovo T61 laptop with an Atheros Wifi card. If I suspend to RAM at school and wake up at home, it does not detect any networks at all and will not work unless I restart the machine. However, the other way around - suspend at home, resume at school, works just fine. When I suspend to RAM at home and wake up at home, it works just fine again.
This is the error that I get when I do /etc/init.d/network restart

I also notice that phy0 seems to be using about 25% of the CPU while it doesn't at other times. Some more hopefully relevant output:

I'd appreciate any suggestions.
