TECHNOLOGY recommends the following device features for accessing wi-fi:
Wireless card compatible with the standard 802.11ac or 802.11a/b/g/n (but with a lower performance level).
If your laptop has not a wireless card with these features, you can buy Wireless USB cards at a moderate price.
Smartphone and Tablet:
The same requirements are for smartphone and tablet as well as for laptop: preferably compatible with standard 802.11ac, or otherwise with 802.11a/b/g/n.
We do not recommend the use of laptop, smartphone or tablet compatible with the only old standard 802.11b/g
and 802.11b/g/n because they can only work using a frequency of 2.4 GHz and a speed of 54 Mbps.
