Wi-Fi, home internet, and the café network
01 · At home
A line into the building, then a private radio bubble
Home broadband — fibre, copper, or a fixed wireless box — arrives at a router. Wi-Fi is only the last few metres, from the router to the laptop. If the router is down, the mobile network may still be fine. If Wi-Fi is weak in a back bedroom, moving the router or using a cable for the television can matter more than changing your mobile operator.
Give the network a password that is not the one printed on a café chalkboard. Rename it so it is not identical to a neighbour’s. Write the password somewhere the household can find it, not only inside one person’s head.
02 · The spare key
Mobile data when the house line stops
A phone hotspot is a spare key, not a second front door. Use it to send the message that the home internet is down, to finish a short piece of work, or to place a call that can ride on data. Watch the allowance. A film on a laptop through a phone will notice the cap before you do. How to read that cap is in where data goes.
03 · Public hotspots
A network with a name you did not choose
Confirm the name with the staff. Lookalike names are an old trick. If two networks differ by a letter, ask which one the café actually runs.
Prefer sites that show a lock in the address bar for anything that matters. Leave banking and medical accounts for a connection you know, such as your own mobile data. This is a habit, not a guarantee. No public network on this page is described as safe in every case.
Forget the network when you leave, so the phone does not rejoin it next week without asking. Turn off automatic joining for hotspots you do not recognise. VPN software is a tool some people add. It does not fix a careless password, and this journal does not sell one.
Which network are you actually using?
Look at the status icons before you diagnose “the internet.” Wi-Fi and cellular indicators are different. On a laptop, the menu bar or system tray names the network. If a page fails on Wi-Fi and loads on mobile data, you have separated a café router from the mobile network. That single comparison saves a long argument with the wrong company.
Fixed offers and mobile offers are sold by the licensed operators and by other internet providers. Current speeds and prices belong on their pages. ANRT’s market observatory is the public place to see how the sector is described in aggregate, not how your hallway behaves. The hallway you can test tonight.
The last few metres are not the line
Fibre, copper, or a fixed-wireless box arrives at a router. Wi-Fi is the radio from that router to the laptop, often on 2.4 GHz, which passes walls a little better and is crowded, or 5 GHz, which is faster nearby and fades sooner. A television that buffers in a back room while a phone beside the router is fine is a Wi-Fi problem. Moving the router off the floor and out of a closed cabinet, or running a cable to the television, changes that room more reliably than changing mobile operator. A mesh pod or a powerline adapter is a later purchase, after you have learned which rooms fail. We do not sell those boxes, and a neighbour’s product is not reviewed here.
Name the home network something you will recognise, and do not reuse the name of the café you sit in. Give it a password that is not the one printed on a chalkboard. Write the password where the household can find it when the person who set it up is travelling. Guest access, if the router offers it, keeps a visitor off the same password you use for everything else.
A riad, a hotel, and a building-wide network
In the medinas the useful evening connection is often the house router, not the outdoor mobile signal. Ask the name of the network that belongs to the building, and whether the password is unique to your room or shared with every room. A shared password is convenient and it means other guests are on the same local network. Use it for maps and calls home. Leave banking for your own mobile data. Forget the network on the way out, the same way you would return a key. If the house line is down, a phone hotspot is the spare for an hour of mail, not for a film on the laptop. How fast that spare empties an allowance is in where data goes.
When the home line stops and the phone still works
Check three things before you report “the internet” as if it were one object. Are other devices in the flat also failing, or only the laptop? Does the phone still load a page with Wi-Fi switched off? Do neighbouring flats in a group chat have the same outage? If the whole building is down, the mobile network may be untouched, and a hotspot will carry a short message to the provider that actually bills the fixed line. If only one room fails, you are back to the router and the walls. If the phone fails too, indoors and on the pavement, look at coverage and at the mobile allowance before you replace the router.
