Frequently Asked Questions
Does the TP-Link UE300C need drivers?
No. TP-Link lists it as plug and play on Windows 11, 10, 8.1, 8, and 7, macOS, Chrome OS, and Linux (Ubuntu). You connect it and the wired link comes up without an install.
Will it work with my MacBook Pro?
Yes. TP-Link specifically lists MacBook Pro 2017-2020 and MacBook Air, along with iPad Pro, Dell XPS 13/15, Surface Laptop 3, Google Pixelbook, Chromebook, Asus ZenBook, and Lenovo ThinkPad X1 Carbon and Yoga 720/910/920.
Can it really hit 1 Gbps speeds?
It supports 10/100/1000 Mbps and runs over USB-C 3.0, which has the bandwidth for gigabit. TP-Link notes you need a CAT6 or higher Ethernet cable to reach 1 Gbps; older CAT5 cabling will cap you lower.
How big is it and will it fit in a bag?
It measures 2.8 x 1.0 x 0.6 inches with a foldable design, so it slips into a laptop bag or pocket. TP-Link positions it for travel, remote work, and conference-room setups.
Does it charge my laptop or add USB ports?
No. The UE300C is a single-function adapter with one RJ45 Ethernet port. It does not include USB-C power pass-through, extra USB-A ports, or video output, so a multiport hub is the better fit if you need those.
