This router is the connection end point for Raspberry Pi, Duet 2 Ethernet and local connection clients (wired or by Wifi). It acts as mesh repeater or switch (regarding to the configured mode). The housing is identical in construction to TPLINK WR840N / WR841N / WR842ND / WR843ND.

<p class="callout warning">Warning: The router's Wifi power is weak. We would not use it a second time.</p>
