The only case it may work is if you connect to open SSIDs without any security/keys. This can be confirmed by attempting a connection which should result in a failure from the new instance. It is unlikely that the new instance created has credential information for the same wireless access points as the phantom. "There is a single physical device, even if there are two instances of the adapter/driver. On Hibernate mode the SSD writes whole 16Gb DRAM data each time that reduces its write cycles resource significantly. It looks like after Sleep mode device initialized differently then after reboot or power on (firmware bug). I did that and got duplicated device instance after reboot/poweron, so it's not a solution. What SSD resource are you trying to 'save' in Sleep mode?" "As a test, delete both instances of the adapter after you come out of sleep, scan for hardware changes, and check if you get only one instance and whether it work properly. On my 2012 MBP, I do not see this behavior under W8.1. The only real solution is to debug the driver and kernel, and find out why this interaction creates a second instance. It is the interaction between the S3 Resume and the Windows Kernel. EFI issues would cause a failure overtime, but that is not the case either. I have seen sleep work on many PCs without any issues, and it works on OS X side, without any issues. Is the W10 installation on Toshiba using BIOS or UEFI? Atheros and Broadcom are not the same. There is a single physical device, even if there are two instances of the adapter/driver. What SSD resource are you trying to 'save' in Sleep mode? Probably the problem is not in Windows, but in wireless adapter firmware, isn't it?Īs a test, delete both instances of the adapter after you come out of sleep, scan for hardware changes, and check if you get only one instance and whether it work properly. By the way, I have one more laptop from Toshiba with Qualcomm Atheros Wi-Fi adapter that works fine after Sleep (S3 resume) without device duplication in Windows 10. I just need certain solution for certain hardware problem from Apple. So I have provided exact explanation with 100% reproducible test, and pictures. Common speaking about everything is speaking about nothing. Could you tell me the exact model name and firmware version for Wi-Fi Airport Card of:MBP Retina, 15" early 2013 and MBP Retina 15" mid 2014 (A1398)?ģ. Probably after walking from sleep both identical duplicated device instances were initialized simultaneously (main and phantom) that resulted in traffic interference and speed reduce. jdoupe wrote: "I have an MBP (Retina, 15", early 2013), now with 10.10.4, and I still experience this issue (slow wifi after waking from sleep - wifi speed is fine after full shutdown / re-start)." But I need Sleep mode working perfect to save SSD resource.Ģ. Resume after Hibernate works fine as I have already described above. Resume after Sleep (S3 resume) duplicates device instance for Broadcom 802.11ac adapter in Device Manager when I close then open the lid. Of course you can repeat steps with Broadcom 802.11ac network driver installed, it doesn't matter, because the Apple should provide us with firmware update to solve this hardware problem.ġ. As a result you always have annoying problem with wi-fi network connection after sleep mode until reboot. Reboot your computer, open Device Manager again with "View" -> "Show hidden devices" option to see (vice versa) the first "Network Adapter" device instance as active, but another one (duplicated) becomes inactive. This is because failed adapter firmware initialization on S3 resume.Ĥ. Now you can see another detected (duplicated) "Network Adapter" device instance as active, but the first one becomes inactive. Put your computer into sleep mode by selecting "Power" -> "Sleep" from start menu and some times later resume it by pressing space bar for eg. Press "Scan for hardware changes" button to detect device instance named as "Network Adapter" and select "View" -> "Show hidden devices" from menu, so you can see only one "Network Adapter" device.ģ. Using Device Manager completely uninstall Broadcom 802.11ac network driver with option "Delete the driver software for the device".Ģ. Seems to be there is a serious bug in BCM43xx adapter firmware (MacBook Pro ) resulting in failed S3 resume initialization (wake-up from Sleep) under Windows 10.ġ.
