wi-fi doesn't work after sleep/suspension in Debian7

hi,

ever since upgrading to Debian7 from 6 on my thinkpad T23, the wifi card(a Netgear WG511) doesn't work after the machine woke up from sleep/suspension. i have to do a machine reboot to have it working again.

I'm using Debian7 XFCE.

any suggestion or fixes?

thanks

One place worth checking is the relationship between network interfaces and swap. Debian stopped using swap after I installed CentOS in a dual-boot set-up. (CentOS may have changed swap's UUID?) I renamed the swap partition and everything returned to normal, except one thing. After resuming from suspend, the internet connection would only work after re-booting. I have not gotten around to trying to fix it, so I cannot offer a solution if the problem is in this direction.
