Today, I just upgraded Windows 7 SP1 of my old laptop, BenQ S41, to the latest Windows 10. After upgraded, both Ethernet and wireless were disabled. I ran the device manager and found the problem “This device cannot find enough free resources that it can use (Code 12)”for both network devices. I google for this problem and found the answer here. I just disabled the PCMCIA device. Other functions seem to work properly.
