Hello! May I know if you have already tried accessing your B315s-938 router's dashboard using the default login credentials? The default username is "admin" and the default password is "admin" as well.
If you have already tried this and it did not work, then one possible solution is to reset the router to its default settings. Please be aware that resetting the router will erase all of your existing settings, including your WiFi name and password, and revert them to the default values.
To reset the router, follow the steps below:
1. Look for the reset button at the back of the router.
2. Using a pointed object like a paper clip, press and hold the reset button for 10 seconds or until the Power indicator light turns off and on again.
3. Release the reset button and wait for the router to reboot.
Once the router has rebooted, try accessing the dashboard again using the default login credentials mentioned earlier.
If you still cannot access the router's dashboard or if you need further assistance, you can contact Huawei's customer support. They may ask for the router's LAN MAC address and IMEI number, so make sure to have them ready.
Hope this helps!
