Home Wi-Fi and router setup in Prague.
A new flat, a router from your provider with an admin page in Czech, and Wi-Fi that gives up two rooms away. Set up, secured and explained in English, so you know what you've got.
What this covers
Why Prague flats are hard on Wi-Fi
Older Prague apartment buildings have thick brick and stone walls, and the internet cable usually arrives by the front door, so the router ends up in the hallway, far from where you sit. Panel buildings have their own problem: reinforced concrete that Wi-Fi barely gets through.
A more expensive router rarely fixes this. Moving the router, adding a second access point, or a mesh system with a unit in each problem room usually does. You'll get a recommendation for what to buy, if anything, with no commission attached to it.
The router from your provider
O2, Vodafone and T-Mobile usually supply their own router, often with a Czech admin page and a default password printed on a sticker underneath. Setup covers the basics most people never get round to: a new admin password, current firmware, WPA2 or WPA3 security, your own network name and password, and a guest network for visitors if you want one.
Slow internet, or slow Wi-Fi?
They're different problems with different fixes. A wired test next to the router shows what your connection delivers. If that's slow too, the issue is on the provider's side, and you'll have measurements to show them. If only the Wi-Fi is slow, it's a placement or equipment question, and that part can be fixed on the spot.
Running new cable through walls is a job for an electrician, and disputes about your contract are between you and the provider. Everything between the socket and your devices is covered here.
Dead spot in the bedroom?
Tell me roughly how big the flat is and where the router sits. That's usually enough to say what would help. First read is free.
What Wi-Fi setup costs
Frequently asked
Do you set up routers from O2, Vodafone or T-Mobile?
Yes. Provider routers use the same settings as any other router, even when the admin page is in Czech. Setup covers the admin password, firmware, security settings, and your network name and password.
My Wi-Fi doesn't reach the bedroom. Do I need a new router?
Usually not. Thick walls are the common cause in Prague flats, and moving the router, adding an access point or setting up mesh usually solves it. You'll get a recommendation before buying anything.
How do I know if my Wi-Fi is secure?
Check that the router's admin password isn't the default one printed on the sticker, that the Wi-Fi uses WPA2 or WPA3, and that the firmware is up to date. If you're not sure how, that check takes a few minutes on a visit.
Can you fix Wi-Fi remotely?
Partly. Router settings can often be changed remotely while you're online, but coverage problems need someone in the flat to see where the signal drops.
