RB411UAHR

The RB411UAHR has it all, just as the name suggests. It has the popular high-speed CPU, a miniPCI-e slot and a SIM slot for 3G modems, a USB 2.0 port for attaching external storage, a regular miniPCI card slot for 802.11abgn wireless cards, a Ethernet port and a built-in wireless radio.

RB411UAHR includes RouterOS - the operating system, which can be a router, ﬁrewall, bandwidth manager, a mobile 3G router, and more - all at the same time.

All throughput tests done with Xena Networks specialized test system and RouterOS v5, according RFC2544, with Ethernet frame sizes 64, 512, 1518 bytes.
Each board is tested with specified number of Ethernet interfaces, to ensure optimal load on hardware.
Values in Italics indicate that the maximum possible throughput was reached, limited only by ethernet ports themselves.
