Moderators Jake Lo Posted September 5, 2016 Moderators Share Posted September 5, 2016 Was the power button blinking when sleeping? what happen when you tap it to wake up? Does it sleep when you close the LID? what happened when you open the LID? Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted September 5, 2016 Moderators Share Posted September 5, 2016 See here. Last post also mentioned alternative kext. Try that too if it didn't work. Best solution is to get a compatible internal device like DW1510 or DW1550 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 5, 2016 Administrators Share Posted September 5, 2016 You may also check that:1) USB wake is disabled in BIOS2) no wake on network access in your Power Savings Pref Pane But most importantly, ensure you have a driver package compatible with OS X El Capitan. Realtek's web site does not list much drivers beyond OS X Mountain Lion 10.8 for 802.11a/b/g/n single-chip devices, so check the dongle's manufacturer's web site. The best solution is to opt for a compatible mini-PCIe or 1/2 mini-PCIe card as suggested by Jake. DW1510 or DW1550 are indeed great hi-speed 802.11n cards. https://osxlatitude.com/index.php?/topic/2120-inventory-of-supported-and-unsupported-wireless-cards/ 1 Link to comment Share on other sites More sharing options...
