Routeros L4 Vs L5 💯 Exclusive

Furthermore, L5 unlocks the NV2 protocol’s full potential in TDMA mode. While NV2 works on L4, the license imposes a hidden limit on the number of wireless clients in a single AP’s connection list. L4 caps effective NV2 client handling at approximately 50-70 active clients before the management frame queue saturates. L5 raises this limit to over 200, allowing a single $200 MikroTik device to serve an entire apartment building. A critical caveat exists: The Cloud Hosted Router (CHR) version of RouterOS uses a different pricing and feature matrix. On CHR, L4 is limited to 1 Gbps throughput, and L5 is limited to 2 Gbps. However, for physical hardware (RB, CCR, or x86 installations), there is no hard bandwidth cap. I have personally routed 3.5 Gbps of NAT traffic through an L4 RouterOS installation on a Dell R620. The license did not stop the traffic; the CPU did. This reveals an important truth: L4’s “1 Gbps optimization” is a marketing suggestion, not a technical enforcement.

A rural WISP has 150 customers on a single tower. They use one 5 GHz backhaul to a core router, three 5 GHz sectors (90 customers), and one 2.4 GHz sector (60 customers). This requires 5 wireless interfaces, exceeding L4’s limit of 3. Furthermore, they use OSPF to route customer subnets back to the core. L5 is mandatory. Attempting this with L4 would result in the software refusing to enable the fourth radio interface. routeros l4 vs l5

A user has gigabit fiber, 50 IoT devices, 5 family members, and runs a VPN server for remote access. They will never exceed 200 PPPoE clients or 3 wireless interfaces. An L4 license (often bundled with the hAP ac³ or RB450Gx4) is perfect. Upgrading to L5 would provide zero tangible benefit, as the session table will never exceed 20,000 connections.
