Denon AVR-X3900H / Denon AVR-X2900H: join a first authorised Wi-Fi network with Scan Networks

First wireless setup, no managed/static configuration to preserve.

Manufacturer-documented Reviewed 2026-11-09 · Revision 1

When this guide applies

Only the explicitly listed models and their separately cited exact regional manuals. First wireless setup, no managed/static configuration to preserve.

Connection scope: Wi-Fi / Ethernet network audio. Symptom: Network audio setup is not working.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Is this a first home-network setup with no installer-managed or existing network configuration to retain?

Do not overwrite an unknown installation.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → Are the intended secure router, wireless antennas and authorised credentials already available?
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-1

Are the intended secure router, wireless antennas and authorised credentials already available?

Credentials belong only in the trusted receiver setup, never in Audio Fix.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → Do you have an authorised HEOS account and accept its required sign-in for the documented network features?
If No → Stop at the unconfirmed condition
If I do not know / cannot check → A required fact is unknown

step-2

Do you have an authorised HEOS account and accept its required sign-in for the documented network features?

No account or password is collected here.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

If Yes, confirmed → May receiver network configuration change while listening is idle and no update is active?
If No → Stop at the unconfirmed condition

step-3

May receiver network configuration change while listening is idle and no update is active?

The current control/network session can disconnect.

step-4

Select Network > Connection > Wireless (Wi-Fi)

Do not alter manual IP, router security or ports.

Look for: Perform only the stated operation, then confirm it was possible.

step-5

Open Wi-Fi Setup > Scan Networks and select the intended network

Use Rescan only if needed; an unknown or missing network stops instead of guessing.

Look for: Perform only the stated operation, then confirm it was possible.

If I completed this → Enter its authorised password in the receiver setup and select OK
If I could not do this → Stop at the unconfirmed condition

step-6

Enter its authorised password in the receiver setup and select OK

Stop on an unexpected update/reset request; follow the actual HEOS sign-in guidance privately.

Look for: Perform only the stated operation, then confirm it was possible.

step-7

Does Network Information confirm the intended connected state locally?

Do not submit SSID, IP/MAC or passwords; association is not proof that a streaming service works.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

Possible result

Checks completed — report the actual result

Completion does not automatically mean the problem is solved. Report what actually happened; no physical test or measured repair is claimed.

steps completed

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

Possible result

Stop at the unconfirmed condition

A required setup or response was not confirmed. Retain the actual observation and consult the exact source/partner manual or official support. Do not escalate to a reset, update installation, internal repair or unsafe wiring change.

next support

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

Possible result

A required fact is unknown

Confirm the actual model, connection, partner capability and state before continuing. Do not guess a menu, interrupt an installation or modify a live source by trial and error.

insufficient data

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
