The Peplink B One is the most capable router in its price class for businesses that can't afford downtime. Whether you're running a restaurant chain, a retail branch, or a remote office, the B One keeps you online through outages that would take other routers offline — bonding your wired connections, cellular, and Starlink into a single reliable pipe. The B One Plus adds an embedded LTE modem; the B One 5G takes it further with a full 5G Sub-6 modem and eSIM for zero-touch setup. All three share the same platform: Wi-Fi 6, dual GigabitEthernet WAN, and SpeedFusion baked in.

The B One series integrates seamlessly with Starlink — load balancing your Starlink with LTE or wired broadband, bonding multiple Starlink connections together, and applying WAN Smoothing to eliminate the packet loss that makes Starlink's intermittent drops noticeable on video calls.

Features

• Multiple WAN Connections - 2× GigabitEthernet WAN, Wi-Fi as WAN, USB-C as WAN for flexibility.
• Embedded Cellular Modem - LTE CAT-4 on B One Plus, 5G Sub-6/Cat 20 on B One 5G, for built-in cellular backup.
• Wi-Fi 6 (802.11ax) – Dual-band 2×2 MIMO for faster wireless speeds and improved coverage.
• SpeedFusion WAN Bonding & Hot Failover – Seamless failover and WAN bonding for increased reliability and performance.
• Dual SIM Slots – Redundancy with physical SIM slots for the B One Plus and B One 5G models, enabling automatic carrier failover.
• 1 Gbps Routing Throughput – High-speed performance for routing and multiple connections.
• InControl 2 Cloud Management – Easy cloud-based management and remote monitoring via Peplink’s platform.
• Built-in eSIM Support – For flexible carrier connectivity, especially with the B One and B One 5G models.

Choose Your Model

• B One: Dual wired WAN, Wi-Fi as WAN, USB-C WAN, and eSIM. No embedded cellular modem. Ideal for Starlink and wired multi-WAN setups where cellular backup comes via a USB adapter or tethered phone.
  
• B One Plus: Everything in the B One plus an embedded LTE CAT-4 modem. The right choice for most branch offices — adds plug-and-play cellular backup without needing an external device.
  
• B One 5G: Everything in the B One Plus, upgraded to a 5G Sub-6/Cat 20 modem with eSIM support. Maximum cellular throughput and the easiest zero-touch setup for multi-site deployments.

Frequently Asked Questions

Does the B One work as a primary router or only as backup?
Both. The B One can run cellular or wired WAN as your primary connection, with the other as backup — or bond them together for higher throughput. Most branch deployments use fiber or cable as primary with cellular as automatic failover.

Can both SIM slots be active at the same time?
No — the B One Plus and B One 5G have a single modem with two SIM slots. You can load two SIMs for automatic failover between carriers, but only one is active at a time. For true dual-modem bonding, look at the MAX BR2 or HD series.

What happens if I don't renew PrimeCare?
SpeedFusion features (Hot Failover, WAN Smoothing, Bandwidth Bonding) are disabled. The router continues to work normally as a multi-WAN router with failover — you just lose the SpeedFusion layer that makes failover invisible. InControl access also lapses.

Is the B One compatible with Starlink?
Yes. Connect Starlink to either WAN port and the B One manages it like any other WAN connection. You can load balance Starlink with a second connection, apply WAN Smoothing to handle Starlink's brief satellite handoff interruptions, or bond multiple Starlink dishes together.

What's the difference between the B One and the Balance 20X?
The Balance 20X is aimed at small business and remote site deployments needing enterprise SD-WAN features like FlexModule expansion, more LAN ports, and deeper routing capabilities. The B One is optimized for simplicity and value at the branch level — easier setup, the Peplink App, and a lower price point. If you need a FlexModule slot or more than 4 LAN ports, go with the 20X.
