Masquerade as the Virgin Media O2 Hub 5x with the WAS-110 or X-ONU-SFPP¶

New subscriber installations
Keep the Hub 5x in active service for roughly a week until fully provisioned and the installation ticket has been closed.
Common misconceptions and answers
- Are the WAS-110, X-ONU-SFPP, HLX-SFPX, or WT-ONU-STICK a gateway/router?
-
No. These are SFU ONTs (not HGUs) that convert Ethernet to PON; they do not provide Layer 7 gateway functions (NAT, DHCP, etc.) A separate gateway/router is required for internet access.
- Are the gateway MAC and IP Host MAC attribute the same?
-
No, they are different. The IP Host MAC is hardcoded as
C4:EB:43:00:00:01, while the gateway MAC is the value found on the the label located at the bottom of the Hub 5x.
Purchase Hardware¶
WAS-110/X-ONU-SFPP ONT¶
The WAS-110 and X-ONU-SFPP are available from select resellers worldwide; purchase at your discretion. We assume no responsibility or liability for the listed resellers.
Purchase SC/APC variant
Although Virgin Media terminate their fiber at the ONT using LC/APC connectors, purchasing an SC/APC ONT guarantees portability and compatibility across the pond or channel.
Angled Physical Contact (APC) tips are polished to 8 degrees. This eliminates signal reflections on the fiber.
Never mismatch APC (green) and UPC (blue). This causes signal loss and can permanently damage the fiber faces.

LC/APC to SC/APC adapter or cable¶
Adapter Promotion
Supporters of the 8311 Community who have recently purchased a compatible module and made a £5+ donation may be eligible to claim a free SC/APC to LC/APC adapter kit (UK only) from Better Internet Ltd. See the community promotion page for details.
A Female LC/APC to Male SC/APC adapter is necessary for connecting to the WAS-110 or X-ONU-SFPP with the provisioned LC/APC cable, or a Male LC/APC to Male SC/APC patch cable, both of which can be purchased at https://www.amazon.co.uk/.
Pre-configuration¶
Before beginning the ONT configuration, ensure you have addressed the following networking requirements to enable successful communication with the PON.
DHCP MAC Spoofing¶
The ISP’s DHCP server identifies your connection via the Unique MAC address of the original equipment. To ensure the ISP "trusts" your new hardware immediately, you must clone the Hub 5x MAC address onto your gateway's WAN physical interface.
The "Lease Window" Issue
ISP DHCP leases are often tied to a specific hardware ID for a set duration. If you swap hardware without cloning the MAC, the server will detect an "unauthorized" device and refuse to issue a WAN IP until the old lease expires.
LCT Access Route¶
To install, upgrade, and configure the ONT, your gateway must be able to reach its Local Craft Terminal (LCT) interface. Follow the Accessing the ONT guide to set up the proper network routing between your gateway and the ONT management plane.
Install ONT firmware¶
You must first install the 8311 community firmware for VEIP support to masquerade as the Hub 5x on XGS-PON.
Upgrading a pre-flashed 8311 WAS-110 or X-ONU-SFPP
If your WAS-110 came with 8311 firmware pre-installed, you do not need to follow the full installation guide below. Instead, you can go directly to the Supplementary Upgrades section to re-install the official 8311 community build to both A and B partitions.
There are two (2) methods to install the 8311 community firmware onto the WAS-110, outlined in the following guides:
-
Method 1: recommended
-
Method 2
The X-ONU-SFPP 8311 community firmware installation requires a two-step process and is more prone to failure or bricking.
This process is not thoroughly documented and can lead to a bricked device
- Step 1: Install the Azores bootloader
-
Skip past to the solution in the following issue tracker on how to install the Azores bootloader.
- Step 2: Multicast upgrade
-
Follow through the WAS-110 multicast upgrade and community firmware recovery guide to install the 8311 community firmware.
Configure ONT settings¶
To masquerade as the Hub 5x, you will need its ONT serial number, which is located on the bottom label as depicted below.

Use your preferred setup method and carefully follow the steps to avoid unnecessary downtime and troubleshooting:
Via web recommended¶
-
Within a web browser, navigate to https://192.168.11.1/cgi-bin/luci/admin/8311/config and, if asked, input your root password.
-
From the 8311 Configuration page, on the PON tab, fill in the configuration with the following values:
Reminder
Replace the
PON Serial Number with the one found on the Hub 5x label.
Attribute Value Mandatory Remarks PON Serial Number (ONT ID) SMBS… PON S/N
Equipment ID MERCV3 Hardware Version 1.0 Sync Circuit Pack Version Software Version A 7.8.3-2410.5 Version listing Software Version B 7.8.3-2410.5 Version listing MIB File /etc/mibs/prx300_1V_bell.ini VEIP and more IP Host MAC Address C4:EB:43:00:00:01 Shared hardcoded MAC -
From the 8311 Configuration page, on the ISP Fixes tab, disable Fix VLANs from the drop-down.
Identify VLANs (Optional: Virgin uses VLAN
100in the UK and10in IEOnce configuration is complete and the fiber is connected, wait for successful authentication (O5 state). You can then use the VLAN Table Analyser to identify service VLANs by copying the table from the VLANs page (https://192.168.11.1/cgi-bin/luci/admin/8311/vlans) and pasting it into the tool.
-
Save changes and reboot from the System menu.
Via shell¶
-
Login over secure shell (SSH).
ssh root@192.168.11.1 -
Configure the 8311 U-Boot environment.
Highlighted lines are mandatory
Replace the
8311_gpon_sn with the PON S/N found on the Hub 5x label.

Verify ONT connectivity¶
Hot plug fiber cable¶
Avoid direct eye contact with the end of the fiber optic cable
After rebooting the WAS-110 or X-ONU-SFPP, safely remove the SC/APC fiber optic cable from the Hub 5x and connect it to the WAS-110 or X-ONU-SFPP.
- Navigate to https://192.168.11.1/cgi-bin/luci/admin/status/overview and, if asked, input your root password.
- From the PON Status section, evaluate that the RX Power and TX Power are within spec.
For troubleshooting, please read the Troubleshoot connectivity issues with the WAS-110 guide's Optical status section.
Validate OLT authentication¶
Check for O5.1 PLOAM status
- Navigate to https://192.168.11.1/cgi-bin/luci/admin/status/overview and, if asked, input your root password.
- From the PON Status section, verify that the PON PLOAM Status is in an 05.1, Associated state.
For troubleshooting, please read the Troubleshoot connectivity issues with the WAS-110 guide's PLOAM status section.
Check for OLT associated VLAN filters
- Navigate to https://192.168.11.1/cgi-bin/luci/admin/8311/vlans and, if asked, input your root password.
- From the VLAN Tables page, if the textarea states "No Extended VLAN Tables Detected", the ONT configuration has not satisfied the OLT.
Router tips¶
Detailed router setup falls outside the scope of the documentation due to the multitude of available solutions.
- Apply the pre-configuration requirements.
- Configure the WAN VLAN to
100in the United Kingdom of Great Britain and Northern Ireland and10in the Republic of Ireland. - Configure the WAN for DHCP mode.
Managed switch tips¶
- Filter or disable any Layer 2 management protocols (e.g., (R)STP) and discovery protocols (e.g., LLDP, CDP, FDP, MNDP, RoMON).
Software versions¶
The Hub 5x uses CWMP instead of OMCI for firmware updates. While the OLT rarely requires approval for specific software versions, keeping the WAS-110 or X-ONU-SFPP up-to-date is beneficial but not strictly necessary.
If you would like to help us maintain the software listing, you can contribute new versions via the 8311 Discord community server or by submitting a Pull Request on GitHub.
