(YLJian) Dual‑Band WiFi Extender — 4T4R MU‑MIMO, 2100Mbps, Gigabit Port, IPv6 — Home Booster, Strong 5 GHz Penetration, Supports Multiple Devices (Rockspace Compatible)

Smart Signal switch and robust antenna design for steady coverage. This dual‑band WiFi repeater uses high‑quality PCB dual‑band antennas and 4T4R MU‑MIMO technology to extend wireless networks on both bands and automatically selects the best channel for a stable, fast connection. Compared with traditional 2T2R MU‑MIMO, it maintains connections while devices are moving by switching to the stronger network. Excellent wall penetration on the 5 GHz band — optimized to work well with optical routers for improved signal through walls and floors. Ideal for multi‑storey homes or large single‑storey bungalows. Fast wired and wireless performance: supports fiber internet up to 2100Mbps with a full Gigabit port and also supports IPv6 for smooth HD streaming and gaming. Wide compatibility: compatible with any wireless WiFi Router, Gateway or Access Point and can extend signals to phones, PCs, smart home devices and wired equipment via the Gigabit Ethernet port — useful for smart TVs, gaming consoles, Blu‑ray players and more. Easy setup and placement: connect in 2 simple steps using WPS or Web Browser Setup; visual signal LEDs help you find the optimal installation spot (Blue = good connection, Red = poor connection). Antenna adjustment: upper antennas rotate 270 degrees and lower antennas rotate 180 degrees to fine‑tune coverage.
