Of late my WiFi speed on the L14 has slowed to a nearly unusable speed. The connection is fine with all other devices in my house. I read some existing threads and there was some discussion about the metal case, internal WiFi wires, Bluetooth, etc. etc. But nothing I found that was conclusive. The problem is not my network/modem/router. I’m trying to make this work so I have a usable device. I was looking at USB WiFi adapters as an option. I was looking at the ASUS USB-AC53 Nano and the NetGear Nighthawk AC1900 for this. But as with everything I see that they are not plug and play with Linux. Has anyone had success with these adapters (or ones like them) for improving WiFi speeds on their L14?
