Eliminate wireless dead zones

The TP-Link TL-WA850RE is a wireless range extender and media bridge compatible with 802.11b, 802.11g and 802.11n standards. It delivers signal rates up to 300 Mbps to extend coverage to areas with poor reception. Setup uses a plug-and-play button method for quick configuration.

Home users extending a single-band network

This device suits households wanting to expand an existing 802.11n network without running cables. The Ethernet port allows a wired device such as a smart TV or game console to join the wireless network. Buyers needing dual-band 5 GHz operation or speeds above 300 Mbps should consider other options.

300 Mbps maximum signal rate

The top wireless link speed of 300 Mbps determines the throughput ceiling for extended connections. Real-world data rates will be lower due to overhead and environmental factors. If your internet plan or local file transfers require sustained bandwidth beyond this limit, a higher-specification extender is necessary.

Questions about this item

Which wireless standard should I pick — 802.11b, 802.11g or 802.11n — for the best speed with this extender?

The extender supports all three standards simultaneously; 802.11n gives the highest link rate of up to 300 Mbps while remaining compatible with older b/g devices.

What does the 300 Mbps figure mean once the TL-WA850RE is plugged in?

300 Mbps is the maximum wireless link rate under 802.11n; actual throughput will be lower and depends on distance, obstacles and the router's own capabilities.

What does the single Ethernet port on this unit actually do?

The port lets you connect a wired device such as a smart TV or games console, or use the extender as a wireless adapter for a desktop PC.
