To see how to remove the wireless card
Then see https://www.youtube.com/watch?v=yzAKcmlaH1M
and see if taping off the pin on the wifi card will bypass the hard block

[doubletwo]

I got it working for a little while, but had to go out for a few hours, so turned the laptop off. When i got back & turned it on, the wi fi options were not showing once again , and i was back to square one.

i changed the CMOS battery, and then went into BIOS and changed the time and date, and loaded default setup, but still there are no wi fi options.

i did the rfkill list command and it cameback soft blocked no
hard blocked no

So what it happening now?
Wi Fi is showing as enabled, and the blue light to show wi fi is working is on, but still no wi fi

Help !!!!

[JeremyB]

Is the ethernet cable still plugged in?

sudo sed -i 's/^REG.*=$/&GB/' /etc/default/crda

There is an odd setting for one wireless connection as it shows IPv4=shared which is something normally used for a hotspot

[Cwashpimp]

1)Open the Network Menu on your panel and select "Edit connections"

2)Select the wirelessconnection and click Properties.
In this dialog, open the IPv4 tab.

3)In the "Method" combo, select "Manual". Then reboot

When i do that, the save button at the bottom greys out, and wont let me save the setting. all the other settings i could save. Im scared to do anything else in case i have no computer at all, so what do i do? do i select one of the other options?

[JeremyB]

Get the computer as close to the access point as you can and run

Code: Select all

iwlist scan

and see if it picks up any signals, you may have disconnect the wifi card from the antenna(s)
