gabrielt94 Posted November 1, 2019 Share Posted November 1, 2019 I'm using my laptop for almost a month without any problem, always connected at 5ghz, yesterday I needed to connect to a 2.4ghz network and saw that the wifi channel is locked at 20mhz, even if I change the configuration on the router to 40mhz the laptop continues connected at 20mhz. I use yosemite's IO80211family.kext I don't use AirportBrcmFixUp.kext ... would have any way to enable the 40mhz channel at 2.4ghz? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 1, 2019 Administrators Share Posted November 1, 2019 40MHz is not necessarily a great option. In addition, some channels are non-overlapping in certain countries so you need to check that out before anything else. This being said, I tried it with my own DW1820A on an access point specifically set for 40MHz operation and I could never connect at 40MHZ, no matter the channel I selected on the AP.

Michelinu Posted November 11, 2019 Share Posted November 11, 2019 Hi, I installed a DW1820A (model 0VW3T3) on Asus ROG Strix Z390-I. Wi-Fi was working OOB, BT didn't. I managed to configure it by using BrcmPatchRAM but only Handoff/Continuity work. It detects AirPods, Trackpad etc. but it fails to connect. I'm currently on macOS Catalina 10.15.1 and I'm using BrcmBluetoothInjector+BrcmFirmwareData+BrcmPatchRAM3 kexts injected via Clover. This is what happens during boot: If I boot Windows and then reboot in macOS, firmware became 5799 and BT works. Can someone give me a hint? Thank you!

Have you merged your fixes to the official repo @ https://github.com/acidanthera/BrcmPatchRAM? PS Hackintool v2.9.4 will now apply the WLAN patching as per this thread when you patch "PCI Devices" in the "Patch" tab. Link to comment Share on other sites More sharing options...

nicegamer7 Posted January 30, 2020 Share Posted January 30, 2020 Hey @Hervé, I just looked at the update in the BCM4350 thread and it made my morning! However, now I'm interested in finding out if these cards can be made to work without disabling ASPM. If you've got time and still have the 0VW3T3 model, I was wondering if you could you let me know what the default value of pci-aspm-default with that card. Thanks Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 30, 2020 Moderators Share Posted January 30, 2020 the default is 0x102 as statement in his guide. it's the same default for my DW1830 and I believe DW1560 too which both are supported without disabling. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 30, 2020 Administrators Share Posted January 30, 2020 By now, you should have grasped that most people experienced issue with those cards when ASPM was not zeroed (disabled). As a rare exception to this rule and as clearly stated in my guide, the 2 x #0VW3T3 I tried in my Latitude 7490 worked perfectly without any adjustment to ASPM. But other BCM4350 models did not and many other people experienced issues with #0VW3T3 without ASPM adjustment. I've no default value to give you, I believe it's dynamically established through communication between the fitted card and the PCIe controller. I've posted what I found to be set by default in my 7490 laptop but I've no way to say if it'd be same in other computers. You'll find it in IOReg as described in my guide. Given the scale of the stability issues encountered by so many people, the advice is, of course, to disable ASPM across the board without further ado.

nicegamer7 Posted January 30, 2020 Share Posted January 30, 2020 I'm well aware that the vast majority of people who have tried this card experience issues with it because of ASPM (I'm one of them). But prior, we had no ideas as to why these issues occurred. So I'm just trying to look into it a bit further, so that maybe, we can gain some more knowledge on it. If I discover anything new I'll make sure to let you guys know. Anyways, I'm grateful for the fix. Thanks. Link to comment Share on other sites More sharing options...
