Having to test with another smartphone or computer can make a huge difference. Nothing is eternal, something that works can be degraded following a problem whether hardware or software. A simple problematic update has already had huge impacts. So it wouldn’t be new and it probably won’t go away anytime soon.
It is therefore always important, as far as possible, to check with several devices whether the problem is not linked to one of them precisely. Opting for the Unifi broadband package is important there.
The first element on which your internet access will depend is the connection you have between the element that allows you to consume and the modem connecting you to your operator. There will be 3 main types of connection used by an individual. Wifi, CPL and cable.
There are of course other means such as optical fibre but which is currently too little used by individuals. However, this will always end up falling into one of the categories of wireless (wifi), network cable or even passage through an electrical network (CPL).
With smartphones, tablets and laptops, wifi has become one of the most used ways to connect to your home network and the internet at home. However, wifi is only a signal that is broadcast from a point to the peripherals and which must then return from the peripheral to that point. If the signal passes through almost everything, this often comes at a fairly high price on the quality of the signal and thus significantly reduces the speed.
Another point that influences wifi speed is the wifi standard used by both your modem and your device. First, there is the IEEE 802.11b standard, which is the oldest but also the slowest. It allows a theoretical speed of 11 Mbit / s. Then there is the IEEE 802.11g standard which can go up to 54 Mbit / s.
Then we have the more recent standards. These will use multiple frequency bands and multiple signals to increase speed. It will therefore be necessary for each sender and receiver to be able to fully exploit these multi-streams. That is not always the case. The IEEE 802.11n standard achieves 450 Mbit / s. The IEEE 802.11ac standard is the most recent and achieves 1.3 Gbit / s.
