Issue Connecting Wifi after pm-suspend


I'm having trouble connecting my Realtek r8187se wireless card after resuming from suspend-to-ram. When I reboot, I can connect with no problems, but after I suspend and resume, wicd will hang at either "validating authentication" or "Getting IP address." I use WPA authentication on my router, and have tried dhcpcd and dhclient. I just upgraded to Linux-2.6.31 and am using Slackware-13.
If I try one of my college's unencrypted hotspots, wicd will not get an ip addr and iwconfig will show a 00/100 reception, even if wicd and iwlist show good reception on all the hotspots, manually pointing it to a certain ap does not work.
I have been told to try reinserting my modules, (rmmod and then modprobe) but have had no luck, I've tried resetting r8169 (the card's driver) and mii, but no luck, and I can't seem to find the supposed magic module that will fix this. Any help will be greatly appreciated.

Code:
lsmod

The way I've found around this (ymmv) is to just rescan for networks before trying to connect. Not sure if it's trying to connect to an old network and freezes, but rescanning works for me.
