Galaxy Player 5: Experimental Wifi Driver

Recently, I started to notice just how "flaky" the wifi is on Venturi. Wifi issues can be tough to diagnose because there are so many "typical" things that can cause wifi issues. In addition to all the typical network connectivity issues that can arise, there are also the ones that are specific to wifi such as interference from microwaves ( ever try to get online while standing next to a microwave that's heating up your burrito? ). So when I read that people are having trouble with wifi on my ROM's I'm pretty skeptical but I finally took the time to take a really good look at wifi today and it does seem that while it does stay connected, that connection is quite sketchy.

There aren't really any errors to go by, things just sort of start timing out. It seems to be one of those sneaky intermittent issues that just really hard to nail down. I decided to swap out the wireless driver we have now and swap in the driver from CM crespo. I alot of ways Venturi is alot like crespo (Nexus S) and I assumed that there wifi driver should work for us and... it does! Since this is one of those obscure issues, it's going to take some time to test but I thought that you guys might want to check it out.


Download: bcmdhd_test.zip
  1. Back up your original driver file @ /system/lib/modules/bcmdhd.ko
  2. Replace it with the one in the zip file.
  3. Reboot.

NOTE: I've assume the .ko file is all that you need.

I'm told that the method above does not work so here is the kernel and all the modules.
Download: BCMDHD_WIFI_TEST.zip


  1. Do a full backup
  2. Install the kernel using heimdall or dd ( If you don't know how to do that then you should not be doing this anyways! )
  3. replace all the modules with the ones in the zip
  4. Reboot.
Or
  1. Wait for me to finished my own testing.
Leave a comment down below and let me know if this works better!
