Manufacturer description

The MikroTik hEX RB750Gr3 is a five-port Gigabit Ethernet router built for wired networks where Wi-Fi is handled elsewhere. Inside the compact 113x89x28mm case sits a dual-core 880MHz CPU paired with 256MB of RAM, enough headroom to run the advanced routing, firewall, VLAN, and VPN configurations RouterOS is known for. IPsec hardware encryption pushes roughly 470 Mbps, so site-to-site tunnels and remote-access VPNs stay fast rather than bottlenecking on the processor. A full-size USB port and a microSD slot expand the 16MB of onboard storage, giving you faster read/write speed for file…
