multiple devices Wi-Fi won't connect | ASUS Router

Troubleshoot multiple devices Wi-Fi that will not join on a ASUS network. Compare devices, refresh saved details, and check model-specific router guidance safely. Written for your devices, with your ASUS router in mind.

More than one device is affected — that almost always points at the router or the internet connection itself, not any single device. Start at the network end.

When several devices cannot join the same Wi-Fi, check the shared network before resetting each device. First distinguish a failed join from joining successfully without internet.

Use the exact ASUS model manual; have the Wi-Fi password before forgetting a saved connection.

The admin page is at router.asus.com. If you use AiMesh, fix the main router first — satellite nodes just mirror its connection.

Troubleshooting steps

First isolate the failed Wi-Fi join

Change one thing at a time. If connected but unable to browse, troubleshoot internet access, not joining.

1Try joining the same network from two devices near the router. Note if the network name appears and whether failure happens at password entry, connection, or after joining.
2Try another device nearby. If it joins, focus on this device; if several fail, check shared network and provider status.
3If practical, test a trusted second Wi-Fi. Hotspots use mobile data; failure on several networks suggests device support, while success points here.

Verify the intended network and current password

The router-admin and Wi-Fi passwords may differ. Ask the owner for current details, especially after changes; never post passwords or verification codes.

1Match the network name to the owner's instructions, including guest or band-specific names. Ask if you are unsure which is intended.
2Enter the confirmed password carefully. If it is rejected again, stop guessing and refresh the saved profile below.

Refresh the saved connection on the multiple devices

Test two device types near the router at about the same time. Record visibility, join errors, and internet access separately.

1If only one device fails, use its own saved-network steps; do not change shared router settings for everyone.
2If a password changed, forget the old entry only on an affected device after confirming the current password, then rejoin once.

Check ASUS status without guessing the model

ASUS settings and status screens differ by model, region, and firmware. The ASUS Router app is not a universal control path; interpret buttons and LEDs only from its exact manual.

1Read the ASUS model and hardware revision from its label and locate the matching manual on ASUS Support. Follow documented status steps; do not guess login details.
2Use the ASUS Router app only if official compatibility information lists this model. Viewing status is safer than changing wireless or security settings.
3If multiple devices fail, check for a provider outage and ask whether Wi-Fi details changed. Do not press reset or alter security as a routine step.

Finish safely and confirm the connection

If it appears only near the router, compare rooms; walls weaken signal. Try another band only with the owner's approval.

1Reserve network reset for an affected device after simple checks; repeating it on every device adds disruption and cannot fix an outage.
2Retest from the same location after each change. Confirm the device joins and a page loads; if not, note the error and which other devices worked. Stop before factory reset.

Restart is a power cycle; reset erases settings. If authorized and no outage is reported, follow the exact provider/manual sequence. Separate modems come first; gateways differ. Never guess IP or DNS values.

3Tell support the model/version, exact error, network visibility, other-device results, and recent changes. Never share passwords or codes.

  • Ask ASUS about customer-owned equipment; contact the provider first if it manages the router.
  • Internet provider: outage reported, several devices affected, or managed service unavailable.

Frequently asked questions

Should I reset every device if none can connect?

No. Check shared router/provider status and recent network changes first; device resets can erase saved networks without fixing a shared fault.

Does ASUS use the same setup screen on every router?

No. Menus vary by model and firmware. Use the exact manual; a brand does not confirm login or light meanings.

Should I factory-reset the router to reconnect?

No. Factory reset can erase service settings. Follow the documented restart procedure and ask the owner before resetting.
