FAQ Wi-Fi and home network

My Wi-Fi keeps dropping out. What can I do?

The usual culprits are an overcrowded channel (lots of networks nearby), interference from the neighbours, or outdated router firmware. In your router settings, try switching to a less busy channel — for 2.4 GHz, ideally 1, 6 or 11; for 5 GHz, automatic is fine. If that doesn’t help, it could be a faulty Wi-Fi card in the laptop or the router itself. We can check it for you — call +420 774 777 774.

Can you replace my router?

Yes, router replacement is routine for us. We’ll either set up your new router or recommend and supply a suitable model based on the size of your flat and the number of devices. Setup includes secure configuration, changing the default passwords and optimising the channels. Book a slot on +420 774 777 774, and ideally bring your internet provider’s login details with you. For larger flats or houses, consider going straight to a mesh system.

What does WPA3 mean?

WPA3 is the latest security standard for encrypting Wi-Fi networks. Compared with the older WPA2, it offers stronger protection against password guessing (so-called dictionary attacks) and better protects open public networks too. If your router supports WPA3, definitely turn it on. Older devices that don’t support WPA3 can usually still connect in a WPA2/WPA3 backward-compatibility mode.

I have a weak signal in the next room.

Signal is dampened most by reinforced-concrete walls, large mirrors and aquariums. The cheapest fix is to move the router to an open spot, ideally up high. If that’s not enough, a mesh system (two or more units that cover the whole flat) will help, or at least a more powerful router. At our shop at Viniční 3587/216 in Brno-Židenice we’ll advise you on both the choice and the installation.

Someone connected to my Wi-Fi. What should I do?

Change your Wi-Fi password right away in the router admin — use at least 12 characters, a mix of letters, numbers and special characters. Also check whether you have WPS (Wi-Fi Protected Setup) enabled, as it’s easy to abuse — if you don’t need it, turn it off. Then go through the list of connected devices and look for any unfamiliar MAC addresses. If you’re stuck, bring the router to us in Brno-Židenice and we’ll set it up.
