Fiddling with this yourself will then quickly take you over the legal limit. This means that the equipment you can buy will usually already be using the maximum permitted transmission strength under the law. (See Fribruksforskriften).Īny wireless device sold in a country with such laws must be approved in accordance with the local legislation. Local laws in for example Norway clearly specify both what frequencies and which signal transmission strengths are allowed for indoor and outdoor wireless networks.

If your router is like this, log in to the settings web page and look for a Wi-Fi menu where you can split the two frequencies into two separate network names.Actually amplifying your router or extender's wireless signal to extend its reach runs the risk of being illegal in many countries. That’s done for convenience, but it means you can’t choose which network to connect to. Many routers combine the two frequencies into one network name. That’s why you might be able to get better range from your router by forcing your phone or laptop to connect to your router’s 2.4GHz network. (Incidentally, this is why 5G is promising such fast speeds, because it uses much higher frequencies-called millimetre wave-but these signals have a tough time getting through glass, trees and even rain.Ģ.4GHz, on the other hand is better at delivering a signal over a greater distance, at slower speeds. The higher the frequency, the shorter the wavelength. And 5GHz signals cannot penetrate walls, ceilings, desks, and, yes, people as well as 2.4GHz signals. Many people think the latter is better because it offers faster speeds.

Wi-Fi can use one of two frequency bands: 2.4GHz or 5GHz.
