Hi ,
I have Dell Inspiron 15 3521 laptop.
MAIN ISSUE: I have a bad Wi-Fi signal strength.
- I have other laptops and the problem only appears on mines.
- I have installed Windwos 7(one time Ultimate and one time Professional) and Windows 8.1 (both time Pro), and after 4 different installations i concluded that the OS is not a problem.
* IMPORTANT: When i use it in Safe Mode the Wi-Fi signal is much better(maybe as it should be, but MAYBE).
- The DRIVERS: i downloaded them from the official site of dell.com and installed them (there is no yellow question mark on any of them)
* IMPORTANT: i doubt that the chipset driver is problem because on the official site it says that the chipset driver is Intel HM77 , when i install it in device manager it says that is installed Intel(R) HM76 Express Chipset LPC Controller - 1E59.
When i try to update it manualy it says that the best version is already installed.
Also i have problem with the Intel Managment Engine Interface driver . On the official site dell.com when i make System Scan it says that the Intel Managment Engine Interface driver needs to be updated. I try to update it manualy but still same problem , it says that the best version is already installed.
- The other settings: I have already tried with Short and Long , and Only Long ( the advanced settings for the Wifi adapter) but when i put it from Long and Short > Long , the signal only increases a bit but still is not what needs to be.
- ALso i have disabled the setting (to save power, by turning off the Wifi or sth. and other details) but still i can't fix it.
Can anyone help me ?
