This is the **TP-Link TG-3269 Gigabit PCI Network Adapter** (model number clearly shown as TG-3269 on the box).
It's an older wired Ethernet network card designed to add or upgrade a desktop computer's network connection to **Gigabit speeds** (up to 1000 Mbps / 1 Gbps). Key details include:
- **Interface**: 32-bit PCI slot (the conventional PCI type, not PCIe – common in pre-2010 motherboards).
- **Port**: Single RJ45 Ethernet port.
- **Speeds**: Supports 10/100/1000 Mbps with auto-negotiation; full duplex (up to 2000 Mbps theoretical) and half duplex modes.
- **Features**: IEEE 802.3x flow control, jumbo frames (up to ~7-9KB depending on version), VLAN tagging (802.1Q), priority tagging (802.1p), and includes both standard and low-profile brackets for different PC cases.
- **Compatibility**: Works with Windows (up to Windows 8/10 in many cases, though drivers may need manual installation on newer OS), Linux, and some older systems. It's based on a Realtek chipset.
This was a budget-friendly option back in the late 2000s/early 2010s for adding Gigabit Ethernet to older PCs that only had Fast Ethernet (100 Mbps) onboard. Today, it's somewhat outdated since most modern motherboards have built-in Gigabit (or faster) Ethernet and use PCIe slots instead of legacy PCI.
The box matches the official product packaging from TP-Link. If you're planning to use it, check your motherboard for a compatible PCI slot!
