rtl8188ce wifi adapter is not detected after installing newest realtek driver

Question

When I use click_no_wait function as shown below,

begin
  $browser.buttons[1].click_no_wait
rescue =>e
  puts e.message
end

It throws this following error

"undefined method `join' for nil:NilClass"

Can anyone please guide me why this error happens and How could I resolve this problem?

Solution

I finally found the problem. Since the old driver had a lot of problems with the wifi connection stability I added a custom config file which disabled the powersaving mode. This option seems to be no longer valid for the new driver and stopped the new driver from loading.

If you have the same problem, then go to

/etc/modprobe.d/

and delete the rtl8192.conf.

After a reboot the driver should be loaded automaticly/you can load it yourself with

sudo modprobe rtl8192ce

Remove the begin-rescue-end to output the whole error, then add it to your question.

please write the value of button variable.

Most likely your buttons does not contain two elements. If you want the first element, keep in mind theat indexes are 0 based.

@Rogue_Leader, What is the difference, both are one,isn't it?

@SachinSingh It's not exactly button, so value is not here, but I accomplish through '$browser.button(:class,'GoButton').click_no_wait', it's working fine now ,thanks.

@BroiSatse Thanks for you comment, but I am aware of the fact that it's starts from index 0, and problem was not that, because I couldn't click that element using the above code, but I couldn't use click_no_wait methods on that. however I achieved through '$browser.button(:class,'GoButton').click_no_wait'

No, the code you've given will only return the error name, not the stack trace, which is vital iun order to pin down exactly where the error is thrown. In any case, this is not a stable way to locate elements. You should use an ID -- $browser.button(id: 'my_login_button').click_no_wait -- or at least a class name -- $browser.buttons(class: 'default-submit-button')[1].click_no_wait -- if possible

@Rogue_Leader Ok, Understood, I usually do that, But since I was interested to know the error I printed like that, I solved problem already as you mentioned. '$browser.button(:class,'GoButton').click_no_wait'. Thank you.
