Some of the most common questions that Telia's technicians receive are about wireless networks.

- Either that you do not have one and want it, that you want to expand your existing one, or that you have poor coverage, says Magnus Henriksson, who is one of Telia's technicians on site.

The use of the SD-WAN system is, therefore, an upgrade from outdated computer network frameworks of the past as they are detached from traffic management and hardware-based monitoring functions.

Poor coverage may be due to the signal from the access point not being able to cover the entire office. This is solved, for example, by acquiring more access points, something that may require some cabling. Another solution is to transmit the signal to a larger area with the help of wifi repeaters.

But the fact that the wifi network works poorly may also be due to the fact that there are too many wireless networks in the same place, for example if the company is located in an office hotel.

- There may be 20-30 networks that appear when the computer is to connect. They can interfere with each other if they are on the same channels. Then you have to go in and change the channel in the router, says Magnus Henriksson.
