Vodafone 5G broadband and GigaCube: set-up and signal

• Your plan may already have started. If you're a new customer, Vodafone's terms say a plan ordered online or by phone and sent by post starts the following day, which should be the day it's delivered. Bought in a store, it starts straight away, even if the kit is being delivered to your home. With click & collect it starts the following day, whether or not you've collected it yet. If you're an existing customer taking new equipment on a new agreement, the plan starts on the day the equipment is delivered, or the day you collect it if you buy or collect it in a store. Set it up as soon as you have the box.
• The 14-day clock starts on delivery. Vodafone's 14-day cancellation period runs from when you receive the equipment, or from the day the last item arrives if you ordered more than one. That's your window to test properly and cancel without an early termination fee.
• Stick with Vodafone's kit and SIM. Vodafone says you must use its router on 5G Broadband plans, and its terms say the hubs are only for the SIM supplied with them.

Vodafone's own set-up page for the indoor 5G Hub is a short video, How to set up your 5G Hub indoors, on Vodafone UK's YouTube channel, rather than a written list. Its separate help pages cover the parts that decide whether it works well:

• The SIM. Find the SIM slot on the back of the hub, open the cover and gently push the nano SIM in until it clicks.
• The spot. Vodafone says the hub should sit by a window, in an open space, upright, away from heating sources, at least 1 metre from other electrical items, and with nothing covering its top.
• The lights. Once it's on, the signal light (marked 1 on Vodafone's diagram) shows whether you're on 5G or 4G and how strong the signal is, and the system light (marked 2) is the one Vodafone's no-internet troubleshooter asks about. The signal colours are explained further down.

The best spot for signal isn't always where you'd normally put a router, so try more than one window, upstairs as well as down.

If the hub won't get online

Vodafone's no-internet troubleshooter for the 5G Hub starts by asking you to check the set-up against its instructions, then to look at the system light:

• No light at all: Vodafone says no power is reaching the hub. Check the connections and try a different plug socket.
• Red, and you got the hub less than 24 hours ago: the hub is usually ready to plug and play, but Vodafone says the SIM can take up to 24 hours to activate. Wait until the 24 hours are up, then try again.
• Red, and it's been more than 24 hours: check Vodafone's network status checker for a local outage. If the network is fine, restart the hub at the mains (off for ten seconds), check its position, then take the nano SIM out of the slot on the back, wait a few moments and put it back. If none of that works, the last step is an online chat.

The Outdoor Hub arrives with its SIM already fitted. The outdoor unit is powered through a PoE (Power over Ethernet) adaptor, which sends power along the ethernet cable that plugs into the bottom of the hub. Vodafone says the outdoor unit is IP65-rated, which means it's designed to resist water and dust.

Find the strongest spot first

Vodafone's method is to power the hub on through the PoE adaptor, then carry it around all sides of the property while watching the SIGNAL QUALITY display. Outdoors is best, but you can also go round the inside walls. Note where the number is highest. The maximum is 100.

Example (made-up readings): front wall 74, side wall 81, back fence 63. You'd plan around the side wall, if you can fit it there safely and run the cable inside.

Choose how to fit it

Vodafone's terms list four ways to install the Outdoor Hub, depending on your property and where the signal is strongest. Its online set-up page has a separate video for each method, so pick the method first and watch the matching video before you start:

1. Indoors on a stand, which Vodafone says suits renters.
2. Indoors, stuck to a window with the supplied double-sided adhesive pad, which it suggests for a block of flats.
3. Outdoors on a pole or drainpipe (you'll need a screwdriver).
4. Fixed to an outside wall (you'll need a drill), which Vodafone recommends only for people confident with DIY.

Safety and permission

The terms put installation on you, and Vodafone doesn't inspect your property. They say:

• Don't install it in an unsafe place, including unsafe high-up positions and rooftops, or anywhere it could end up under water.
• Wear protective clothing. If you can't fit it safely at any stage, get professional help.
• Vodafone won't pay for any changes to your property or put it back as it was afterwards.
• If you don't own the home and fitting it needs the owner's consent (drilling a wall fixing, for example), getting that consent is your job. Our guide to broadband for renters covers talking to a landlord.

Vodafone calls the speed your hub gets from the mast the network speed. That isn't the same as the speed a laptop or phone gets over Wi-Fi from the hub. A hub with excellent signal can still feel slow in a back bedroom. A strong Wi-Fi connection can't make up for a weak signal at the hub, either.

Indoor 5G Hub: the light colour

Outdoor Hub: the SIGNAL QUALITY number

From 60 to 100 the hub is on 5G. Under 60 it's on 4G.

If you can't read the display, Vodafone says to switch the PoE off at the mains, wait ten seconds, switch it back on and look again.

Why the hub might be on 4G

Vodafone's terms say 5G Broadband is designed to run on its 5G network where it's available, but may fall back to 4G where 5G isn't available or when the network fluctuates. The same terms list what affects speed: your location, the type of walls and windows in your building, how many people are using the network, the surroundings outside, coverage, the equipment, de-prioritisation (some traffic getting lower priority when the network is busy) and whether the equipment is set up correctly. Placement is the one you control. For the radio side, see our guides to 5G frequency bands and 5G Standalone.

Vodafone sells two speed levels, up to 50Mbps or up to 150Mbps depending on where you live and your plan. Its terms say these are maximums, not guaranteed, and that your speed may vary through the day and at times be lower than the maximum. When you test, compare against the right one, using our broadband speed test near the hub. Our guide to why speed test results differ explains why one reading isn't enough.

Vodafone no longer sells the GigaCube but still supports it. Its set-up help points to the instructions in the box and a set-up video on Vodafone UK's YouTube channel, and suggests online chat if set-up fails.

To get into the settings of a 4G or 5G GigaCube, Vodafone says:

1. Connect your phone, tablet or laptop to the GigaCube's Wi-Fi.
2. Open a web browser and go to https://giga.cube.
3. Enter the password printed on the bottom of the GigaCube.

Once you're in:

• Wi-Fi name and password: go to Settings, type a new name in the SSID box (SSID is the network name your devices see), choose Modify password, enter the new one, then Next and Save. Every device will need reconnecting afterwards.
• Block a device: Settings, then Security, then Device Management. Pick the device and choose Block.
• Block a website: Settings, Security, Parental Controls, Web Filter. Choose Blacklist, then Add, and type the site (without http or https). Set it to On and Apply.
• Set internet times: Settings, Security, Parental Controls, Internet Access Time Control. Choose Blacklist, Add the days and times, tick the devices to restrict and Apply. See also our parental controls guide.

If the GigaCube won't connect to the mobile network

The APN (access point name) is the setting that tells the GigaCube how to connect to Vodafone's mobile data. Go to Settings, then Dial-up, then Profile management, choose the APN settings and Apply. If there's no profile, Vodafone lists these details for a new one:

Vodafone's factory reset help covers the 5G Hub, the Outdoor Hub and its fibre routers but not the GigaCube. We haven't found Vodafone reset steps for it, so check the instructions that came in the box or ask Vodafone by chat before you press any reset button.

Vodafone's slow-speed troubleshooter asks which hub you have, then branches on your signal reading. Every route ends in an online chat, for which Vodafone asks you to have your account number and the steps you've already tried.

5G Hub: blue signal light

A blue light means the hub is on 5G. Vodafone's steps then run in this order:

1. Check the hub's position against Vodafone's placement list above.
2. Disconnect some devices from the Wi-Fi. Vodafone says there may be too many devices connected for the hub's current bandwidth.
3. Check your speed on the device. The troubleshooter asks whether it's significantly slower than you'd expect.
4. If it's just one device: turn it off for 15 seconds and back on, or switch airplane mode on for 15 seconds. Turn on Wi-Fi compatibility mode on the hub if it's an older device, and install the latest software updates (charge and back up the device first).
5. Restart the hub at the mains, leaving it off for ten seconds.
6. Still slow? Start an online chat.

5G Hub: green or yellow signal light

Here Vodafone treats the 5G signal as weak. It asks you to check its network status checker for a local outage. If the network is fine, the next step is to reposition the hub, and if that doesn't help, to chat.

Outdoor Hub

The troubleshooter asks you to read the SIGNAL QUALITY display on the side of the hub, restarting it first if you can't read the display. If the number is below 60, it asks you to check for a local outage, then restart the hub by switching the PoE cable off at the mains for ten seconds, then walk round all sides of the property holding the hub and note where the signal is stronger, because that's a better place to fit it. After that, it's a chat.

Slow at the same times of day

If everything slows down at the same times each day, one possible cause is local network demand: Vodafone's terms allow it to de-prioritise some users' traffic during peak periods or congestion, and its 5G Broadband page says speeds can vary with how busy the local network is. Note the dates and times, because a record like that is useful if you later report the problem.

If the household's usage is the worry rather than speed, Vodafone's terms describe 5G Broadband as an unlimited data plan for personal, non-commercial use. They also say that where usage isn't for personal use and/or goes over 1TB a month, Vodafone may look into whether it fits its acceptable use policy, and may move the customer to a more suitable plan if it decides the usage is for other purposes. Our guide on how much data home broadband uses helps you check where you stand.

Vodafone has interactive troubleshooters for no 5G internet and for a 5G connection that keeps dropping, and a network status checker on its help site. The 5G Hub's no-internet steps are in the indoor hub section above. For drop-outs on a 5G Hub with a blue light, Vodafone's steps match the slow-speed list without the speed check. These checks cover the basics for either hub:

• Restart properly. For the 5G Hub, switch off at the mains for ten seconds. For the Outdoor Hub, switch the PoE off at the mains, wait ten seconds and switch it back on.
• Reseat the Outdoor Hub SIM. Switch the PoE off at the mains. Loosen the two screws on the weatherproof panel at the bottom with the supplied Allen key, then pull off the panel and the ethernet cable. Take out the nano SIM, wait a few moments and push it back until it clicks. Plug the cable back in and refit the panel without over-tightening the screws, so the seal stays weatherproof.
• Look at what changed. Vodafone's terms list weather, network works, network damage, the number of people online and interference from hills, tunnels or buildings as things that can affect service. Note if drop-outs line up with any of them.

Factory reset: last resort

A factory reset puts the hub back to its original settings, including the Wi-Fi name and password, so every device will need reconnecting with the default details. Vodafone's steps:

• 5G Hub: press and hold the button on the front and the WPS button on the base at the same time for about 10 seconds. Wait for the hub to turn off and on again. A solid white WiFi light on the front means the reset worked.
• Outdoor Hub: remove the weatherproof panel with the Allen key and find the RESET button just above the SIM slot. Hold it down for 10 seconds with a SIM tool or paper clip and wait for the hub to restart. A solid blue SYS light on the side means it worked. Refit the panel without over-tightening. To reset the indoor router, Vodafone points you to its Power Hub, Ultra Hub or WiFi Hub instructions; our Vodafone router guide, linked in the first section, sets out the Power Hub steps.

What to have ready when you contact Vodafone

• Your account number.
• The light colour or SIGNAL QUALITY number, and where the hub is placed or mounted.
• Speed test results, with dates and times, near the hub and in the rooms where it's worst.
• The steps above you've already tried, such as repositioning the hub.

Vodafone's terms set out what can happen if service stays poor:

• If Vodafone interrupts the service for maintenance or causes a technical fault on its network, you may be entitled to a partial credit based on how many days you were without service.
• If you have a continuous, materially degraded service for an unreasonable period, or regularly recurring disruption, Vodafone says it may offer alternative equipment and you may be entitled to a price reduction. To get a partial credit or end the agreement, you must report the severe disruption, which Vodafone assesses against your typical usage.
• If the service is materially degraded for an unreasonable period, you may be able to leave early without a termination charge, though the equipment must still go back.
• If you report the equipment as faulty, Vodafone may test it. If it's faulty, you can ask for a repair or replacement. If it turns out to be working, Vodafone may charge for testing and postage.

If you complain and it isn't resolved, the six-week rule applies. For complaints first raised on or after 8 April 2026, you can take the dispute to the provider's free alternative dispute resolution (ADR) scheme six weeks after you first complained, or straight away if the provider sends a deadlock letter. Earlier complaints keep the old eight-week wait. Our guide on how to complain about a broadband provider takes you through it.

Changing your mind: Vodafone's returns help gives you 14 days to send back a 5G Hub or Outdoor Hub. It must be complete, with the packaging, instructions, accessories and any free items, plus the dispatch note as proof of the purchase date. Vodafone emails the details and a pre-paid returns label. If you cancel within the 14-day cancellation period, its terms say all equipment goes back, including SIMs and cables, and you pay for the service used up to that point.

Who owns what: Vodafone's terms say it owns the indoor 5G Hub, the outdoor unit of the Outdoor Hub and the cables. You own the Power Hub (the indoor half of the Outdoor Hub) and the SIM once the 14-day period has passed. Vodafone-owned equipment has to go back within 30 days of the service ending, and the terms say to take the SIM out before returning a 5G Hub. The terms also say you must keep proof of postage. If you don't return it, Vodafone charges a non-return fee, and your contract summary sets out the details.

Leaving later: the rolling monthly plan can be cancelled with 30 days' notice and no early termination fee, Vodafone says. On a 12- or 24-month plan, leaving early means 30 days' notice plus an early termination fee.

Moving home: the kit and plan can only be used at your approved address, so you need to tell Vodafone and it checks 5G coverage at the new one. If coverage is there, it may be able to carry on your plan; depending on what's available, it may offer a different broadband product instead. If it can't provide 5G Broadband at the new address, its terms say you can cancel without early termination fees, though Vodafone-owned equipment still has to go back. Our guide to moving home with Vodafone broadband covers what happens next.

Comparing options: if 5G isn't reliable enough where you live, you can compare deals at your postcode through our partner's comparison. It shows the packages available for your address but doesn't switch you itself. Vodafone's packages are on our Vodafone broadband deals page, and our broadband providers page gives an overview.
