Important D-Link DIR 850L Firmware Update Required

Category: Hardware, News/  Posted On 27/09/2017

We’ve been advised by our hardware supplier that an important firmware update is required to address a security vulnerability with your DLINK DIR-850L router.

SkyMesh customers using the D-LINK DIR-850L router are urged to perform this update as soon as possible.

All SkyMesh customers who own the affected DLINK router have been emailed from info@skymesh.biz confirming this.

There are 6 steps which typically take less than 10 minutes to complete for non PPPoE customers.

1: Download the new firmware

Please note the firmware contains two separate files.

Download the latest firmware

2: Connect to LAN

Please ensure your computer is plugged into any 4 of the black ports on your router. If you do not have LAN, please follow these instructions.

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

1. Leave your modem router powered on. Using a paperclip or something sharp press the reset button at the back of the unit and hold it for 10-15 seconds.
2. 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: 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.

Click on the heading marked ‘Settings’ at the top of the page. Select ‘Internet’ from the drop-down menu.


Click on the drop-down menu marked ‘My Internet Connection’. Set this to ‘Dynamic IP’.
Click the ‘save’ button at the top of this page to save your settings.

6: Setting up your D-Link DIR-850L WiFi networks and admin password

Click on the heading marked "Settings" at the top of the page. Select
"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.




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!
