Faster and better 5 GHz Wi-Fi
I really had bad and no stable internet over Wi-Fi very often. Since I came across the different frequencies. On the one hand there is the 2.4 GHz and also the 5 GHz frequency. However, many laptops only support the 2.4 GHz frequency, like mine for example.
The advantage of the 5 GHz frequency is that it can receive and transmit many more channels. At the 2.4 GHz frequency, there are only 13 channels. Especially in houses, where there are many apartments with routers, the 13 channels are quickly overcrowded.
Now I have a Wi-Fi USB adapter added. This can also receive and send over 5 GHz and it really works much better! It must be noted, however, that the router can also transmit on this frequency. Buy now
