Huawei B818-263 Firmware Upgrade

Hello!

Please note:

Disconnecting the power supply of your router during its firmware update process may cause damage to the router.

Method 1: Automatic update (when idle)

When Auto-update is enabled, your router can automatically detect new updates for the time period you specify. If a new update is detected, your router will download and install it automatically.

1. Connect your computer to the router's Wi-Fi network (or connect the computer to the router's LAN port using an Ethernet cable). In the browser address bar, enter 192.168.3.1 and log in to the router's web-based management page.

Please note: 

For routers that feature self-adaptive ports, you do not need to distinguish between WAN and LAN ports.

2. Go to More Functions > Manage Updates. Toggle Auto-update on, set the update time of the automatic update, and click Save.

Method 2: Update manually online

You can always check whether new updates are available for your router. If new updates are available, you can download and install them manually.

1. Connect your computer to the router's Wi-Fi network (or connect the computer to the router's LAN port using an Ethernet cable). In the browser address bar, enter 192.168.3.1 and log in to the router's web-based management page.

Please note: 

For routers that feature self-adaptive ports, you do not need to distinguish between WAN and LAN ports.

2. Go to More Functions > Manage Updates and click Update Now to check whether new updates are available for your router. If new updates are available, perform an online upgrade.

Thanks!

@wissal,
First of all thanks for your reply!
Thanks for your explanation but i would like to understand well...
In my hands i have founded and downloaded several firmwares for this B818...
I have:
1) the custom firmware for particolar details made by mobile operators.
2) Generic firmware with several date.
3) Webui made by huawei..

I have seen that these firmwares have different file extantions..like ".exe", like ".ef", like ".bin"...

There is a procedure to follow to update them or not...for example if i could update only the webui and leave the firmware like the old one or i must update the firmware after the webui process?

In the web i can't able to see one video about this process of upgrade...
thanks
