Vention USB 3.0-A to Gigabit Ethernet Adapter Gray 0.15M Aluminum Alloy Type (CEZHB) – Upgrade an Older PC’s 100Mbps LAN Port to Full Fibre Speed
The Vention USB 3.0-A to Gigabit Ethernet Adapter Gray 0.15M Aluminum Alloy Type (CEZHB) is a USB-A to RJ45 network adapter that adds a 10/100/1000Mbps Gigabit Ethernet port through a USB 3.0 port. Many older laptops and office desktops shipped with 10/100Mbps LAN ports, so on a fibre plan faster than 100Mbps they waste most of the bandwidth. This adapter lets the same computer run at full Gigabit speed, provided it has a USB 3.0 port. Equally, it replaces a faulty onboard network card or adds a second network port to a desktop or mini PC, without opening the case. It works plug-and-play on Windows, macOS and Linux.
For durability, the adapter uses an aluminium alloy and ABS shell, nickel-plated connectors and a 0.15m cable with tinned copper conductors under aluminium foil shielding, at a slim 4.5mm diameter. As a result, a home user in Kitengela on a 200Mbps fibre plan with an older laptop, an IT technician in Nairobi CBD reviving a PC with a dead LAN port, or a network admin in Mombasa adding a second interface to a Linux firewall box gets the full wired speed they need.
