cowboy_wilhelm Posted March 4, 2021 Share Posted March 4, 2021 Welp, the DW1820A I ordered from everyone's favorite online auction site finally arrived. The seller's image for the card and the sticker on the card both indicated it was the 0VW3T3 card. I installed it yesterday and don't have Bluetooth. Wi-Fi works, but maxes out at 25 Mb/s. I used an Ubuntu disk to "try Ubuntu" and had functioning Bluetooth (transferred a file to my phone) and full Wi-Fi (300+ Mb/s wireless on 400 Mb/s connection). Turns out I'm lucky and got a card with the 0023 subsystem ID instead of 0021. So... what to try next, if anything? It seems odd that it functions, albeit slowly. I assumed it would either work or not work. I guess I can live with it, but 25 Mb/s seems painfully slow these days. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted March 4, 2021 Administrators Share Posted March 4, 2021 @cowboy_wilhelm Subsystem id does not matter. Check that your configuration matches our recommended settings posted in the BCM4350 guide. Link to comment Share on other sites More sharing options...
cowboy_wilhelm Posted March 5, 2021 Author Share Posted March 5, 2021 The config I was using had pci14e4,43a0. I tried 43a3 and 4353 instead, but neither made a difference. What did work was adding brcmfx-country=#a as a boot-arg. That got it from 40 MHz to 80 MHz. I thought I had BrcmBluetoothInjector, BrcmFirmwareData and BrcmPatchRAM3, but they’re not showing up as installed in Hackintool. Guess I’m still missing something there.

Administrators Hervé Posted March 5, 2021 Administrators Share Posted March 5, 2021 It depends in which country you are and what the default code of the card is set to. Link to comment Share on other sites More sharing options...
