How do you change the settings of the wifi antenna? Also how would you manually disable wifi in the phone preferences? If you manually disable it, why do you need to change the settings of the wifi antenna? I’ve been trying to block wifi for a while. I downloaded K9 to “blacklist” everything, but apparently you can’t do that on the android. Now I tried another similar site, but I’m having the same problem. If you can help me, I’d really appreciate it. Thanks so much!
