The wireless network in our office is down because of a ransomware attack. IT is swamped with restoring the vital services and may take some time to restore wireless connectivity. But the desktop PC connection wired by an RG45 cable to the network does work. And it is fast (speedtest says 700 mbps speeds in both directions). Desktop PCs typically don't have wireless connectivity. How can I make the desktop a wireless hotspot so I and other workers can connect our laptops to the internet? Pls recommend the hardware we need.
