Wifi error when using a modified galaxy tab kernel


I know that xda-developers forum may be the ideal place to ask such questions, but I haven't had a chance to find the answer there or by extensive searching around the web.

Preliminaries: I'm doing a research on the Android kernel. So I have installed a rooted rom on Galaxy Tab 10 wifi and used a modified Samsung kernel source code to implement my modifications of the kernel. I successfully installed and tested the kernel but...

Problem: The tab works with no problems. The only issue is "wifi error"; it can't communicate with the wireless card. Definitely a driver issue. I have not touched any parts of the kernel regarding wireless communications.

My thoughts: I think I'll only need to install the wifi device driver. My problem is that I cannot find the driver. Where should I look for it? Is it going to be part of the build kernel?

Any help is really appreciated.

Thanks!


Solution

  • OK. I found it after lots of searching! I wish these things could be documented better. I had to include the built Wi-Fi driver module in my update.zip file and apply the update and finally restart. The driver was built under

    drivers/net/wireless/bcm4330/dhd.ko
    

    Now it works fine.
