Slow Wi-Fi or slow broadband? How to check

The expensive mistake is blaming the provider for a problem that stops when you use a cable. Wi-Fi is the radio between the router and the device. The broadband connection is what arrives at the router. They fail in different ways, and only one of them is fixed by switching.

Check in this order

1. Is the problem one device, or several?
2. Does it improve when you stand next to the router?
3. Have you tested with an Ethernet cable, where the device allows it?
4. What speed does that device’s Wi-Fi connection actually support?
5. Does it happen at particular times, especially evenings?
6. What does the provider’s estimate or your contract say the connection should do?

What the answers can mean

Wi-Fi coverage may be the issue if a cable is fine and the problem follows distance or walls. The device or local setup needs checking if only one device is affected. The broadband connection needs a closer look if a wired test is also poor, at more than one time of day. One low speed test is not enough to call it a line fault.

If the cable test is acceptable, the next step is placement, a mesh system, or fewer devices fighting for the same radio — not a new 24-month contract. If the cable test is poor, contact the current provider about a fault before you compare leaving. Switching is a later decision, and only if the connection itself is the problem.

A new provider cannot see through brick. They can only send a different bill to the same cupboard.

Wired is the truth

A test on a phone in the garden is a weather report. A test on a laptop next to the hub, with a cable, at 8pm, twice, is evidence. If that evidence matches the contract, switching provider is a very expensive way to buy a longer ethernet cable. If it does not, raise a fault with the evidence, then compare.

Mesh is furniture

Buy it if the house is long or the walls are proud. Do not buy it to fix a 20 Mbps copper pair. Do not let a retailer count mesh as a reason the gigabit was necessary. Radio is a local project. The line is a contract.

The ethernet sentence

One cable, one laptop, one test at the hub. If that number is the tariff and the sofa is not, you have a radio problem — cupboard, coats, 2.4 GHz, a TV. If that number is a third of the tariff, stop shopping mesh. The Hardware and Home pieces in this issue are the rest of the sentence. The line is the WAN. Say WAN when you mean WAN.
