Dual-band PCIe Wi-Fi adapter

The TP-Link TL-WDN4800 adds IEEE 802.11a/b/g/n wireless to a desktop through a PCI Express x1 slot. It operates on 2.4 GHz and 5 GHz bands with three detachable 2 dBi RP-SMA antennas. Windows 7, Vista and XP are supported with drivers on the included resource CD. This card suits owners of older towers who need cable-free connectivity without USB dongles.

Fits a spare x1 slot and frees USB ports

Installation requires one free PCI Express x1 lane inside the case and the low-profile bracket supplied. The card draws power from the slot itself, leaving all motherboard USB headers and rear ports available for peripherals. Detachable antennas let you position them for best signal or replace them with higher-gain models using the standard RP-SMA connectors. No external power adapter or additional cabling is needed.

Sustained throughput on 2.4 GHz and 5 GHz

Each band can reach a theoretical 450 Mbps using 64-QAM modulation under continuous load. The operating range of 0 °C to 40 °C and humidity tolerance of 10 % to 90 % non-condensing keep performance stable during long streaming or gaming sessions. WPA-PSK and WPA2-PSK encryption handle security without adding noticeable overhead. Buyers needing 802.11ac or ax speeds, Bluetooth or more than three spatial streams should look elsewhere.
