Have you tried pushing the reset button with a paperclip for 10+ seconds? On Huawei E5186s it's a small hole on the side of the router if I remember correctly.

It should reset the router to factory defaults, including the password.

Try this then : Red Reset button, located next to the battery, below the lid. It must be pressed with a narrow object and press it to reset the device's original settings.

Kiisseli67,...You were right,I found the button for RESET, in the back to the battery,
and changed the password.
