- First, confirm the connection is live, then run a wired speed test to establish a baseline.
- Set up the router properly: change the default admin and Wi-Fi passwords and position it well.
- Copper-based connections go through a line-management training period of around ten days, so early speeds can fluctuate.
- If speed is below your minimum guaranteed level once stabilised, report it as a fault.
The moment your new broadband goes live is the right time to do a handful of checks that set you up for good performance and security. A few minutes of attention now prevents weeks of avoidable frustration later, and establishes the baseline you would need if you ever had to raise a fault.
Confirm it is live and test it
First, check the connection is actually working, lights on the router and a device online. Then run a speed test, ideally over an Ethernet cable rather than Wi-Fi, so you measure the line itself without Wi-Fi interference muddying the result. This wired test is your baseline; note it down with the date and time.
Set up the router properly
Before relying on the connection, secure the router. Change the default administrator password, set a strong Wi-Fi password, and give your network a name you recognise. Position the router centrally and in the open rather than tucked behind furniture, since placement has a large effect on Wi-Fi coverage. A few minutes here improves both security and everyday performance.
Allow for the training period
If you are on a copper-based connection such as FTTC, do not panic if early speeds fluctuate or seem below expectations. The network's line-management system spends roughly the first ten days learning your line and balancing speed against stability. Full-fibre connections do not need this settling period. Judge a copper line's speed after it has stabilised.
New connection checklist
| Check | Why |
|---|---|
| Connection live | Confirms activation succeeded |
| Wired speed test | Baseline free of Wi-Fi interference |
| Change passwords | Security from day one |
| Router placement | Maximises Wi-Fi coverage |
| Note the date | Evidence if a fault arises |
If something is wrong
If the connection is not live on the first day, restart the router and check cabling before contacting your provider. If, once a copper line has stabilised, your speed is consistently below your minimum guaranteed speed, report it as a fault, give the provider its fix window, and keep your evidence. Your early baseline test is exactly the record that makes such a complaint stick.
Frequently asked questions
How do I know my broadband is live?
Check the router's status lights and connect a device to confirm it can reach the internet. Then run a speed test, ideally over an Ethernet cable, to confirm the line is working and to record a baseline.
What speed should I expect on the first day?
On full fibre you should see close to the expected speed quickly. On copper-based connections such as FTTC, early speeds can fluctuate during the line-management training period, so do not judge performance on day one.
Why is my new broadband slow at first?
Copper-based connections go through a training period of around ten days, during which the network balances speed against stability and speeds can fluctuate. This is normal; judge the speed after it has settled. Full fibre does not need this period.
What is a DLM training period?
Dynamic line management is the system that optimises a copper-based broadband line, adjusting it over roughly the first ten days to balance speed and stability. During this period speeds can vary before settling to a stable level.
Who do I contact if my broadband is not working on the first day?
Restart the router and check cabling first. If it remains down, contact your provider to report it, and note the date, since a failure to activate on the promised date may attract automatic compensation from participating providers.
