djuby Posted May 5, 2020 Author Share Posted May 5, 2020 Do I need to get rid of any unused kexts? Any extra entries in the config.plist? DSDT? Could it be USB Configuration as reported in this guide? https://github.com/syscl/XPS9350-macOS/issues/145 Link to comment Share on other sites More sharing options...
djuby Posted May 12, 2020 Author Share Posted May 12, 2020 OK. I think I found a solution to the problem. It may not be the right one, but at least my ping times to my local router are consistent and the same before and after sleep. WiFi is stable, so is Bluetooth. AirDrop is on and off - sometimes it works and finds devices on the network, sometimes it does not. So, what I did to fix the WiFi is I updated the following kexts to the latest version possible and removed any patches related to BCM from the config.plist file. Here is the list of kexts currently in my EFI/Clover/Kexts/Other folder related to WiFi and Bluetooth: - AirportBrcmFixup.kext - BrcmBluetoothInjector.kext - BrcmFirmwareRepo.kext - BrcmNonPatchRAM2.kext - BrcmPatchRAM3.kext I think it won't hurt to update Lilu.kext and WhateverGreen.kext too. Hope this helps others having issues with DW1830 WiFi adapter. Best regards. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 12, 2020 Administrators Share Posted May 12, 2020 That Bluetooth-related setup is incorrect. You never said if you use the same SSID for 2.4 and 5GHz. If this is the case, there could be a chance that, on wake, your laptop picks up the 2.4GHz network for which there is interference from Bluetooth. If at all, possible, differentiate 2.4 from 5GHz network using different SSIDs, then compare behaviour. NB: no double post on the forum please.

djuby Posted May 12, 2020 Author Share Posted May 12, 2020 Hi Harve, My 2.4GHz and 5GHz networks always had different SSIDs. What do you mean by "That Bluetooth-related setup is incorrect."? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 12, 2020 Administrators Share Posted May 12, 2020 It appears you chose to use NonPatchRAM2 AND PatchRAM3 and inject kexts that are not for injection but caching... I would suggest you read up on the matter and opt for the latest Bluetooth injector/firmware patching build (v2.5.3 last time I checked), especially if you inject kexts rather than cache them. Right now, you're doing things incorrectly. Link to comment Share on other sites More sharing options...
djuby Posted May 12, 2020 Author Share Posted May 12, 2020 OK. How do I do the Bluetooth injector/firmware patching? Which kexts do I need to get and which ones do I need to remove? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 12, 2020 Administrators Share Posted May 12, 2020 You could do a bit of research, you know... https://www.insanelymac.com/forum/topic/339175-brcmpatchram2-for-1015-catalina-broadcom-bluetooth-firmware-upload/ Link to comment Share on other sites More sharing options...
