I have an Intel 4965AGN wireless card which worked perfectly fine before I tried updating, but now it doesn't seem to see the networks anymore -- the settings include a list of all of the connections with correct names and passwords, but the system acts as if there is no network in range.

I think these two issues are related to the updated driver for iwl4965 
in 5.3. SL5.2 used the iwl4965 driver whereas 5.3 uses the new iwlagn 
driver. They use *different* firmware, so a user updating from 5.2 -> 
5.3 with previously working wireless will experience the issues you 
describe if the correct firmware is not installed.

In /etc/firmware you will need iwlwifi-4965-2.ucode (note the -2 
revision is required by the new iwlagn driver).

RPMforge has the correct firmware packages (yum install 
iwl4965-firmware). I'm not sure what SL firmware packages are available 
nor what firmwares these packages contain.

Hope that helps,
