USB 2.0 wired network adapter

The No Sew TCC-S20A adds a 10/100 RJ45 Fast Ethernet port to laptops, tablets and mini PCs that lack a built-in LAN jack or have a damaged port. It connects via a USB 2.0 Type-A plug and draws power from the host device. The compact dongle weighs 25 grams and includes an 18 cm cable to reduce strain on the USB socket. Plug-and-play operation is supported on Windows 11, 10, 8.1, 8, macOS, Chrome OS and Android.

Fast Ethernet over USB 2.0

The adapter uses the RTL8152B chipset to deliver up to 100 Mbps wired throughput, which is the practical ceiling of the 10/100 Fast Ethernet standard. Because the link runs over USB 2.0, sustained speeds cannot exceed the bus bandwidth and will be lower than Gigabit Ethernet. Driver installation is required for Windows 7, XP, Vista and Linux distributions. The device is backward compatible with USB 1.0 ports, though performance will be further limited on that interface.

Compact travel-ready build

A streamlined black enclosure measuring 53.5 by 24.3 by 16.2 mm houses the circuitry and a short tethered cable that eases packing for school, office or travel use. The fixed cable means there is no separate cord to lose, but it also prevents replacement if the connector is damaged. The RJ45 jack accepts standard Ethernet cables for a secure latch connection to routers or switches. Buyers who need Gigabit speeds or a detachable cable should consider other solutions.

Questions about this item

Which version of this USB Ethernet adapter should I choose?

The TCC-S20A is the single model offered; it provides a 10/100Mbps RJ45 port over USB 2.0 Type-A with an ~18cm cable and weighs 25 grams.

What does the 10/100Mbps rating mean when I plug it into my laptop?

The adapter negotiates up to 100Mbps Fast Ethernet over the RJ45 jack; actual throughput is limited by the USB 2.0 bus and the RTL8152B chipset.

What interface does it use and what speed does that cap in practice?

It connects via USB 2.0 Type-A (backward compatible with USB 1.0), so the bus caps real-world throughput well below the 100Mbps Ethernet link.
