The process of creating a WiFi hotspot on Ubuntu is relatively easy. Once set up, you may use an industrial PC (IPC) as an All-in-one solution and save the space of having a router in an industrial environment. Other smart home or IOT sensors can connect to your IPC wirelessly through the Wifi hotspot.
The writer will use the TP-Link Archer T2U as the wireless adapter in this article. You may refer to this article and install its driver (TP-Link WL823N driver is also provided).
