Plugging In Iphone Disables Wifi

So I have everything working now. The mechanical switch is enabled in bios and is working when I flip it back and forth as well!!!
Thanks for your guys help. Sometimes just pointing someone in the right direction is all that is needed.
I uninstalled my wireless adapter from LL.
Then, I went ahead and re-flashed the bios on the motherboard.
I then hooked up to Ethernet and installed another WiFi adapter and used LL to install the drivers for it.
I restored Bios to defaults and checked to see if everything worked with the alternate adapter! And all was well.
So I put back my original wireless card and re-installed drivers via Ethernet. To see if it was broken. It's not.
I don't know what step did it, but its all working.
It may sound not worth it to most, but it really didn't take me much time. Probably spent 2-3 hours total on this.
Thanks again guys!!! :045: :045: :62: :027:

@ trinidad Thanks!
So I went into the bios to check if the WiFi adapter was enabled and to see if there were settings for the switch.
I disabled the WiFi adapter rebooted and then enabled the adapter and rebooted. This didn't help.
I then disabled the WiFi adapter and there is a setting where i can select "none" for the wireless switch. This setting essentially ignores the switch. I rebooted and still nothing.
Still blocked by rfkill.
Next I enabled my wireless device and ignored the wireless switch. Nothing, still blocked. :banghead
So, I removed rfkill.
--- Code: ---sudo apt-get purge rfkill
sudo apt-get purge --auto-remove rfkill
--- End code ---
Both commands removed something. So then I rebooted. Upon reboot I went back in to the Bios, I made sure to have enabled wireless adapter and I left the wireless switch setting set to "none" which essentially ignores the switch.
I now have WiFi access back on my laptop.
So you are correct! :045: :bow It is in fact the switch causing the issue.
Is there a way to go about fixing this? I would prefer the switch worked properly and I would also prefer rfkill to be re-installed as I understand Linux uses it as a kill-swtich when needed.
So I have re-installed rfkill

So now I am no longer blocked and have access to the internet.
But my switch is basically ignored/disabled.
Is there a way to fix this?

So I had 30 whole extra minutes before bed..
So, I took some initiative. I think I have confirmed that RF-Kill is a Linux program.

Well, what I was reading showed "softblock." But I wanted to try it anyway.

Trying that didn't get me anywhere. So I am assuming that "softblock" refers to a software block of Wi-Fi and "hardblock" refers to a hardware block of Wi-Fi.
In assuming this, should my next step be to remove and re-install the kernel for my BCM4312 adapter?

However, my suggestion until,someone more knowledgeable replies, is what about picking up a WiFi USB?
I have resorted to using these on occasion when the WiFi stops working on some of my student placed laptops. The majority are plug and play, just make sure they are linux compatible, and they are very reasonable cost wise. I haven’t bought one recently, but in Canada they are probably between $10-15 Canadian so converted to USD they might be free (lol :011:)

I have tried Wi-Fi USB in the past and it doesn't seem to fix the issue. If it does its only temporary. When I worked at a machine shop the CNC machines ran on really old computers and were very basic. Every time someone plugged in their phone the Wi-Fi magically went away. Management loved it! It kept people offline while working. But eventually we would find times where we actually needed them to connect to the network, and we tried the USB adapters, sometimes it worked, sometimes it didn't.
Thanks for the reply! I appreciate it!
