The WiFi-key is your WiFi password.
Your WiFi network name and password are printed on the label on the bottom of your new router. You can scan the QR code with a device to connect instantly without typing your password. Additional copies of this label are included in the router box. The label shows:
If your internet stops working, try these steps before calling us. You don’t need internet access to follow them.
WiFi connections introduce a number of factors that can often result in you seeing lower speeds than you get from a device plugged directly into the router. There are a few things you can do to ensure that you are getting the best WiFi signal possible:
5 GHz is faster but more affected by walls and obstacles. 2.4 GHz reaches further and travels through walls more easily, but is slower and more prone to interference from household electronics.
If you use Lightning Fibre WiFi extenders, the router and extenders create a mesh network, allowing your devices to stay connected as you move around your home.


Our installation team have installed an ONT (Optical Network Terminal or Optical Modem).
Our fibre cable comes into your home and connects directly into the ONT, allowing us to deliver your full fibre service.
It is important that you do not move or alter your ONT. The only device plugged into the ONT should be your router.
You should never need to adjust your ONT unless directed by us.


Your WiFi 7 router plugs into the ONT and all your devices should connect to the router via a WiFi or wired connection.
For the fastest, most reliable service, plug a network cable into one of the yellow LAN ports on your router and the other end into your device. WiFi speeds are dependent on a compliant device and good wireless conditions.
If you would like to use your own router, please see the section below entitled “Can I use my own Router” or contact our team.




This wireless router supports dual-band wireless WiFi 6 (ax) technology, allowing you to enjoy superior connectivity with extremely low latency.
The router plugs into the ONT to receive its connection, in turn all your devices should connect to the router, be that via WiFi or a wired connection.
There are a number of ports labelled LAN 1-4, into which you can plug any wired devices for the best possible connection. LAN port 1 supports speeds up to 2.5Gbps, whilst ports 2-4 supports speeds up to 1Gbps.
If you wish to use your own router, please see our guide on the website or talk to our customer support team.
If you have ordered our Lightning Voice (digital virtual landline service) you will be provided with a phone adapter which plugs into the phone port in the router. Plug your own phone into that adapter.

Yes, we allow our customers to use their own router if desired. Whilst Lightning Fibre cannot guarantee inter-operability with any third-party routers, our network operates using fully standards-based technology and thus most routers or firewalls should work on our network with a few changes to the default settings.
Please note that our troubleshooting ability may be limited when a third-party router is in place, although we will do our best to help resolve any issues that might arise. The Lightning Fibre router may be required in order to test your connection.
If you have a Lightning Fibre supplied router and you subsequently use your own router, please retain our one as this will need to be returned to us when your contract ends or you may incur a fee.
Whilst you can use your own router, you may not use your own modem. The provided ONT (fibre modem) is an integral part of your broadband service and should not be disconnected or replaced. We do not support the use of third-party ONTs on our network.
Any third-party routers must support the following:
We do not recommend connecting anything other than a router or firewall to the ONT.


If you have a Lightning Fibre extender, to provide better WiFi coverage to deadspots around your property, this communicates wirelessly with your router, but requires power.
Your engineer will normally set up your extender during installation. If you ever need to set it up again, for example after a factory reset, or if you get a new extender, there are two ways to do it.
[IMAGE: WIFI_EXTENDER_PLACEMENT_DIAGRAM] Add the placement diagram here: router on one side, extender in the middle, problem area on the other side.
Tip: If using the extender wirelessly, don’t place it too close to the router, as this can actually cause interference rather than help, or too far away, as it won’t get a strong enough signal. Halfway to the problem area is usually the sweet spot.

Your Lightning Voice digital virtual landline service (VoIP) has a range of features similar to a traditional landline, including voicemail, call barring and caller ID controls. These can be managed by dialling the codes below or through your customer portal.

Permanently hide you number from anyone you call. To activate: *141* / deactivate: #141#
Release Caller ID for a Single Call
If you are permanently withholding your number and would like to release your number for a single call, dial 1470 followed by the number you would like to call to show your caller ID for that call only.
Withhold Caller ID for a Single Call
If you’re not withholding your number permanently and would like to withhold your number for a single call, dial 141 followed by the number you would like to hide your caller ID for that call only.
Last Caller ID
Dial 1471 to hear the number of your last caller. Press 3 to have the number repeated.
Erase Last Caller ID
Dial 1475 to remove the record of your last received call.
