When I boot my laptop (Lenovo ThinkPad E540, CentOS 6.7, Kernel 2.6.32-573) wireless works fine. After I put the machine to sleep (e.g., close the laptop, wait a minute, and reopen), wifi is not only disconnected but disabled. It seems like there should be a way to get it back, but I cannot figure it out. My guess is there is a power setting that disables the wireless controller during sleep but I would think it would be re-enabled when the machine wakes up again.
When I right click on the network icon in the panel, "Enable Wireless" is grayed out. None of the F## keys seem to do anything under Linux. Restarting the Network service is likewise ineffective. I'm forced to reboot to get wifi back.
Any ideas?
