UFB - PC to ONT Isolation via PPPoE
Posted by Jay Wattage on 29 June 2018 10:25 PM

The following steps will allow you to connect your Windows 10 PC directly to your Fibre ONT.

This is a good way to troubleshoot and isolate UFB issues, to determine if the cause is related to your router or local network.

Before you begin:

  • If you have limited technical experience, we don't recommend you attempt this. Please consult our support team for further guidance (0800 477 333 Mon-Fri, 8am-10pm)
  • Windows 10, computer hardware and network card drivers must be up to date
  • When testing, ensure any anti-virus and anti-malware have been suspended or turned off temporarily, otherwise this creates a great CPU overhead on traffic that severely affects speeds
  • Monitor the CPU/HDD and Ethernet performance in task manager, to ensure the computer has not bottle-necked the speed test
  • Once you have completed your testing, make sure to disable VLAN tagging on your network adapter configuration


Step 1) Connect your Windows Computer directly to the ONT with a Cat5e or Cat6 Ethernet Cable

Step 2) Wait for your computer to identify the network → Right click on the Network icon in the system tray → Select 'Open Network and Sharing Center'


Step 3) Click on 'Change adapter settings'

Step 4) Right click on the relevant interface → Click 'Properties'

Step 5) Click on 'Configure' → Click 'Ok'

Step 6) Select the 'Advanced' tab → Select 'VLAN ID' under 'Property:' → Set 'Value' to 10 → Click 'Ok'

Note of VLAN setting:

- Ensure Priority & VLAN option is enabled.

- Some network card drivers will not have VLAN ID enabled/avalible by default, you may need to get the latest driver update from the manufacturers website.

Step 7) Return to 'Network and Sharing Center' → Click on 'Set up a new connection or network'

Step 8) Select Connect to the 'Internet' → Click Next

Step 9) Click on 'Broadband (PPPoE)'

Step 10) Enter the radius Username and Password → Click 'Connect'

Step 11) Wait for connection to establish

Step 12) 'You are connected to the Internet' will be displayed if successful
