Your customer then asks you if it would be worth the investment for him to have Ethernet cabling installed to reach each of his workstations, instead of connecting them by Wi-Fi to his network. Specifically, he wants to know if that would speed up communications for the workstations. You examine his router and find that it's using 802.11ac Wi-Fi. Would you advise him to upgrade to Ethernet? Why or why not?
Yes, because Ethernet is faster than 802.11ac. Yes, because wired connections are always faster than wireless connections. No, because installing Ethernet cabling is more expensive than the increased speed is worth. No, because 802.11ac speeds are faster than Ethernet.
