Important D-Link DIR 850L Firmware update – Standard (No LAN)

Customers using the DLINK DIR-850L router are urged to perform a firmware update to address a security vulnerability. For customers who have purchased this modem from SkyMesh, we sent you an email linking to these instructions

1: Find the default WiFi Name (SSID) and Password

Check the sticker at the base of the D-Link DIR-850L and make sure you can see the Default WI-FI Name (SSID) and Password.  These will allow you to reconnect to the WiFi after the Factory Reset at step 4. Then make sure you are connected to your DLINK’s WiFi network.

2: Download the new firmware

Please note the firmware contains two separate files.

Download the latest firmware

3: Apply the update

Click apply update below to continue.

Apply Updates

Enter your admin username (‘admin’) and your admin password.

Click on the ‘Management’ heading in the top-right corner of the screen. Select ‘Upgrade’ from the drop-down menu.

Settings updated

Click the ‘Select File’ button.
Select the first file (‘FW210WWb03.bin’) and click ‘Upload’. This file will most likely be in your ‘Downloads’ folder.
Select the second file (‘FW220WWb03.bin’) and click ‘Upload’. This file will most likely be in your ‘Downloads’ folder.

After both firmware upgrades have been installed, we recommend connecting your computer to the LAN 1 port of the DIR-850L with an Ethernet cable. This will mean that you will still be able to access your router after performing a factory reset.

4: Complete a factory reset

– Leave your modem router powered on. Using a paperclip or something sharp press the reset button on the bottom of the unit and hold it for 10-15 seconds.

– Release the reset button and allow your router 2-3 minutes to reboot after a factory reset. Once the reset is complete your power light should return to a solid green state.

5: Reconnect to your router 

– Open the list of available WiFi networks on your computer.
– Select the network that corresponds with the WI-FI Name (SSID) on the base of the router (e.g. dlink-0000).
– When it asks for a WiFi Password, type the Password that is found on the base of the router (will be a mixture of letters and numbers and is case sensitive).

6: Set up your router 

Click below to start setting up your router.

Setup

You may see a setup wizard. Click the ‘Cancel’ button to be taken to the main menu for your router.

"Wireless" from the dropdown menu.

Your wireless settings should be as follows:
2.4GHz
- Status: Enabled
- Wi-Fi Name (SSID): The network name that you noted earlier.
- Password: The WiFi password that you noted earlier.

5GHz
- Status: Enabled
- Wi-Fi Name (SSID): The network name that you noted earlier.
- Password: The WiFi password that you noted earlier.

Click on the 'Save' button at the top of the page. 
You will then be disconnected from the default Wi Fi network and reconnected to your own. 




Click on the 'Management' heading at the top of the page and select
'System Admin' from the drop-down menu. 

Type the admin password that you used previously and click save. 

Your upgrade is now complete.
