DTNT

DTNT is a Windows desktop toolkit for inspecting wireless conditions, discovering local devices, measuring speed and checking saved network profiles. It suits AV, low-voltage and network technicians who need several field diagnostics in one application. The free edition is useful for routine checks, while the paid tier targets technicians who need deeper tests and portable evidence.

Overview

DTNT’s appeal is consolidation. One Windows app combines a nearby-radio survey, active-range IP scanning, speed tests, profile review and network diagnostics. That makes sense for technicians moving between installations who would otherwise switch among separate utilities.

The free tier covers the principal inspection workflows, but the decisions and documentation that matter in more demanding jobs are concentrated in Pro. A purchase is for one purchaser or internal technician seat and can be activated on up to three Windows devices controlled by that purchaser. Teams needing several independent users should account for that restriction.

Key features

Wireless survey

The free app surveys nearby radios and reports SSID, band, channel and security with live channel context. It is a practical snapshot for identifying what surrounds an installation. Pro adds best-channel guidance and richer lane-pressure detail, turning observation into a more direct basis for channel selection.

Discovery and diagnostics

IP Scanner scans the active range, remembers and labels hosts, filters results and copies addresses. Those functions suit inventory and initial fault isolation. Pro adds selected-host follow-up and TCP checks, plus continuous ping and trace route; the free plan provides only a one-time ping. Choose Pro when troubleshooting requires repeated reachability checks or service-level probing rather than a quick list of devices.

Speed, profiles and evidence

Free includes speed tests with saved history and profile review. Pro can reveal saved Wi-Fi keys and export speed history plus profile or network evidence in JSON or CSV. Exportable records are useful when a technician must hand findings to a client or retain a job trail; key revealing should be limited to authorized work.

Data handling and validation

Network inventories, saved Wi-Fi keys, device passwords, exports and diagnostic logs are not automatically uploaded to Denali Tech. Saved device-login passwords are protected locally with Windows data protection for the current Windows account, although other settings, logs, inventories and exports are not all encrypted by DTNT.

Online Pro activation and validation send purchase and device identifiers to Denali Tech’s fulfillment service. Startup update checks request release metadata from the DTNT website. After activation, the app can continue for up to fourteen days following the last successful validation if the licensing service cannot be reached, so fully disconnected operation is not a Pro strength.

Pricing

Free

The Free plan costs nothing. It includes the main app workflows, Wi-Fi survey and live channel view, IP Scanner, speed tests with saved history, profile review and one ping. It is the sensible starting point for occasional checks and basic inventories, but it omits channel recommendations, advanced host checks, continuous diagnostics, key reveal and exports.

Pro

Pro costs $59, paid once as a one-time purchase at the current launch price; the planned regular price is $99 after the launch window. It adds best-channel guidance, selected-host follow-up, TCP checks, JSON/CSV exports, saved-key reveal, continuous ping and trace route. There is no recurring renewal, but the license is limited to one purchaser or internal technician seat and three controlled Windows devices. Support is offered at [email protected] on a commercially reasonable basis, without a guaranteed response time or uptime commitment.

Platforms

DTNT supports Windows desktop only. The maker recommends installing through Microsoft Store and describes Stripe as the checkout provider. Technicians working across macOS, Linux, Android or iOS will need a different primary tool or a separate companion utility.

Who it's for

DTNT is a good fit for independent AV, low-voltage and network technicians who want wireless survey, host discovery and basic diagnostics together, especially when a Windows laptop is already standard equipment. Pro is aimed at recurring service work where channel advice, targeted TCP checks and JSON or CSV evidence justify the purchase.

It is less suitable for multi-technician deployments because one purchase covers one seat, for users requiring broad operating-system coverage, or for environments that cannot permit periodic online validation. Organizations with strict encryption requirements should also review what remains stored locally without DTNT-wide encryption.

Pros and cons

• Pros: Combines Wi-Fi visibility, IP discovery, speed history, profile review and diagnostics in one Windows app.
• Pros: Free tier includes meaningful survey, scanning and history workflows rather than a time-limited trial.
• Pros: Pro exports JSON or CSV evidence and adds targeted TCP, continuous ping and trace-route checks.
• Pros: Inventories, keys, passwords, exports and logs are not automatically uploaded.
• Cons: Pro requires startup revalidation and permits only fourteen days offline after the last successful check.
• Cons: The license covers one technician seat, despite activation on up to three devices.
• Cons: Local protection is uneven: Windows data protection covers saved device passwords, but not all other local data is encrypted by DTNT.
• Cons: Windows-only support rules out technicians needing a cross-platform toolkit.

Verdict

Choose DTNT if you are a Windows-based field technician who values one place for wireless surveys, local discovery and escalating diagnostics, with Pro evidence exports available for a one-time $59 launch price. Look elsewhere if you need multiple licensed technicians, cross-platform coverage, fully encrypted local storage or dependable operation without online validation.
