If you use a Peplink router in an RV, boat, overland vehicle, service vehicle, mobile office, or remote deployment, you probably don't want to open a laptop or dig through your phone every time you want to check your internet connection.

That is exactly the problem ToughDisplay™ is designed to solve.

ToughDisplay is a compact 2.8-inch touchscreen control and monitoring interface for supported Peplink routers. It gives you an always-available view of important network information while also putting many commonly used Peplink controls directly at your fingertips. It connects to the router over Wi-Fi and uses Peplink's internal API, so the display itself does not require an Ethernet data connection.

And now, ToughDisplay is becoming even easier to integrate into permanent RV, marine, vehicle, and equipment-panel installations thanks to two new options: an OEM-style flush-mount bezel and a Gigabit USB-C PoE splitter.

Here's a closer look at what ToughDisplay can do and how these new mounting and power options expand where you can install it.

What Is ToughDisplay?

ToughDisplay is essentially a dedicated touchscreen interface for your Peplink network.

Instead of reaching for a phone, tablet, or computer and logging into your router every time you want to check a connection, ToughDisplay gives you a small screen that can remain mounted where it is convenient and visible.

That makes it especially useful for RVers and boaters who want a connectivity display alongside their other onboard system monitors, as well as commercial and field users who may not always have a laptop available.

In the video, we show examples ranging from permanent RV cabinet installations to commercial deployments where ToughDisplay is built into portable equipment or suitcase-style systems. In each case, the goal is the same: see what's happening with your Peplink network at a glance and make common adjustments without opening the full router administration interface.

The ToughDisplay itself measures approximately 90mm x 62mm x 16mm, giving it a compact footprint for dashboards, electronics cabinets, control panels, and other locations where space is at a premium.

See Your Peplink Connections at a Glance

One of the biggest benefits of ToughDisplay is visibility.

When you're relying on multiple internet connections—perhaps cellular, Starlink, campground Wi-Fi, Ethernet, or another WAN source—you want to know which connections are active and which ones your Peplink router is prioritizing.

ToughDisplay provides a real-time multi-WAN dashboard with status information, failover priorities, cellular signal indicators, connected client counts, router uptime, and other network information. The current implementation supports visibility for as many as 16 simultaneous WAN connections, including cellular, Ethernet, Wi-Fi WAN, USB modem, IPSec, and VLAN-as-WAN connections where supported.

That can be particularly helpful in a mobile environment.

Imagine you're parked under trees and your Starlink connection becomes partially obstructed. Rather than opening a laptop and logging into your Peplink administration page, you can quickly check your WAN status on ToughDisplay and adjust connection priorities as needed.

Change WAN Priorities from the Touchscreen

ToughDisplay doesn't just tell you what your network is doing. It also gives you access to common administration functions.

One of the most useful is the ability to reorder WAN priorities.

If one connection becomes unreliable, you can move another connection higher in the priority list or disable a connection that you don't want the router to use.

For RVers, boaters, and other mobile users who regularly move between locations, this can make day-to-day connectivity management much faster. A connection strategy that works perfectly at one campsite, marina, or jobsite may need to be adjusted at the next one.

Instead of treating those adjustments like a full network administration session, ToughDisplay turns many of them into quick touchscreen actions.

Monitor Detailed Cellular Signal Information

A basic cellular signal icon only tells part of the story.

ToughDisplay can expose detailed cellular information from supported Peplink hardware, including metrics such as:

• RSSI
• RSRP
• RSRQ
• SINR
• Cellular network technology
• Carrier information
• Active cellular bands and carrier aggregation details
• PCI and channel information where supported

It can identify network technologies including LTE, LTE-A, 5G NSA, 5G SA, and other supported cellular modes.

For users who frequently troubleshoot cellular connections or optimize antenna placement, having this information available on a dedicated display can be significantly more useful than simply knowing whether a connection shows three bars or four.

Switch SIMs, eSIMs, and FusionSIM Profiles

Multi-carrier connectivity is one of the reasons many customers choose Peplink equipment in the first place, and ToughDisplay brings many of those cellular controls onto the touchscreen.

Depending on the supported Peplink router and modem configuration, ToughDisplay can display physical SIM information and provide touchscreen SIM switching and priority controls. The current feature set also includes support for eSIM and FusionSIM profile information where available.

This can be especially useful if you maintain multiple cellular options—for example, one carrier as your primary connection and another as a backup.

Keep an Eye on SpeedFusion

For anyone using Peplink SpeedFusion, knowing whether your tunnels are healthy can be just as important as knowing whether an individual WAN connection is online.

ToughDisplay includes SpeedFusion tunnel monitoring with visibility into profile and tunnel status, routing states, connection states, RTT, remote IP information, bandwidth information, and per-WAN tunnel statistics where supported.

The current ToughDisplay feature set supports monitoring for up to 16 SpeedFusion peers.

For users depending on SpeedFusion for connection bonding, failover, WAN Smoothing, or other mobile connectivity applications, that means important tunnel information can remain just a tap away.

See Who Is Connected to Your Network

Ever wonder how many devices are currently connected to your Peplink?

ToughDisplay can show total, wired, and wireless client counts along with a connected-client list. Depending on what information is available from the router, you can also view details including hostnames, IP addresses, MAC addresses, wireless signal information, and upload/download rates.

That makes the screen useful for much more than troubleshooting your WAN connections. It can also provide a convenient snapshot of what is happening on the local network.

Wi-Fi, GPS, Data Usage, and More

ToughDisplay continues to evolve beyond simple WAN monitoring.

Current capabilities include Wi-Fi network visibility and management, supported SSID information, Wi-Fi WAN scanning, LAN and VLAN visibility, and even a tap-to-display QR code that can simplify guest Wi-Fi access.

For Peplink devices providing GPS data, ToughDisplay can also display location information such as latitude, longitude, altitude, speed, heading, and GPS accuracy indicators.

Data-usage cards can provide visibility into usage and quotas for supported connections, including FusionSIM and SpeedFusion Connect information where available.

And for common administration tasks, ToughDisplay includes controls such as Peplink router reboot, WAN priority reordering, and supported Starlink controls when used with compatible equipment.

The result is a small screen that can replace a surprising number of routine trips into the full Peplink web administration interface.

New: A Flush-Mount Bezel for Permanent Installations

The original ToughDisplay enclosure includes an integrated metal rear plate that works well for magnetic mounting, making it easy to place the display in a convenient location and move it when needed.

But since ToughDisplay launched, one of the most common requests has been:

Can I make it look like it was built into my RV, boat, dashboard, or control panel?

Now the answer is yes.

The new ToughDisplay Flush Mount Bezel Kit is designed specifically for the 2.8-inch ToughDisplay and allows it to be recessed into a wall, cabinet, dashboard, switch panel, equipment enclosure, or other flat surface.

Instead of looking like an accessory mounted on top of a surface, the bezel creates a much more integrated, OEM-style appearance.

What's Included with the Flush-Mount Bezel?

The kit includes:

• ToughDisplay 2.8-inch flush-mount bezel
• 90-degree USB-C adapter
• Four black self-tapping mounting screws

The bezel's front dimensions are approximately 120mm x 95mm and it is manufactured from PETG for installations such as RVs, marine environments, mobile equipment panels, and similar applications.

There's another useful detail here: ToughDisplay supports screen rotation.

If the cable routing works better with the USB-C connection positioned on the opposite side of your installation, the display orientation can be flipped in ToughDisplay's settings. That provides additional flexibility when working inside a crowded RV cabinet, dashboard, electronics bay, or marine control panel.

New: Power ToughDisplay Over PoE

The other major request from customers has been more flexible power.

ToughDisplay normally operates from 5V USB-C power, but that doesn't necessarily mean you want to run a dedicated USB power cable all the way to wherever your display is installed.

For installations that already have Power over Ethernet available, MobileMustHave now offers a Gigabit USB-C PoE Splitter designed to make powering ToughDisplay much easier.

The current splitter accepts compatible IEEE 802.3af/at PoE and separates the incoming connection into:

• 5V/2.4A USB-C power, up to 12 watts
• 10/100/1000 Mbps Gigabit Ethernet

That means a single PoE Ethernet run can bring power to the ToughDisplay while still making an Ethernet data connection available at the installation location.
