WIFI connection is not working with Toshiba Satellite L750-BT4N22

Hi friends I am using Toshiba Satellite L750-BT4N22 laptop and I am expensing problem with the WFI in my laptop. Normally I start WIFI in my laptop with the help of Fn+F8 but it has suddenly stopped working and now I cannot turn on my laptop. Now please tell me what should I do to solve this problem?

You have mentioned that you are not able to turn on WIFI in your laptop with the help of F8 key and that is why I would like to tell you that you should try to Toggle wireless on and off by clicking on the TBSWireless file and then you have to check whether it makes any difference or not?

If you don’t know about how to toggle Wireless on and off with the help of the TBSWireless file then you have to follow this steps. You need to first open my computer in your laptop and after opening my computer you have to go to C drive and then open Toshiba folder. Now after that you have to open TBS folder. After opening the TBS folder you have to double click on the TBS wireless folder. Now after that you have to try to start wireless in your laptop and then check whether it makes any difference or not?

After referring your solution I have tried to solve this problem by turning on the wireless by double clicking on the TBSWireless file but after that also I get same problem. Now after that I have also tried to fix this problem by doing system restore in my laptop but that does not help me to solve this problem. If anyone have any solution regarding this then let me know.

You should try to solve this problem by uninstalling the wireless drivers from your Toshiba Satellite L750-BT4N22 laptop and after that you have to install drivers again and aft installing the drivers you have to check whether same problem occurs or not? if reinstalling the drivers does not fix this issue then you have to contact Toshiba support and then tell them about this problem and after hat they will provide you proper solution.
