Your ASUS ZenWiFi BT10 is on and the front LED is solid white, but no device sees the WiFi network. Or maybe the 6 GHz band shows up but the 2.4 GHz is invisible. The BT10 is a BE18000 tri-band Wi-Fi 7 mesh system, and when the radios decide to go silent, it's almost always one of a handful of causes. The good news is that every single one is fixable in under 10 minutes.
Plug a laptop directly into one of the 10G LAN ports with an Ethernet cable and open router.asus.com in a browser. If the admin page loads, the router is alive and just not broadcasting, that narrows things down fast. If you can't reach it, the router itself needs a power cycle.
Here's the order to work through for the BT10 specifically.
The Power Switch on the Back Gets Bumped
The BT10 has a physical power switch on the rear panel. It's easy to flip off when you're moving the router around or plugging cables into those 10G ports. Check that it's set to On and that the power adapter is fully seated.
If the switch was off, flip it on, wait about 90 seconds for the front LED to go solid white, then check your devices. This alone fixes the issue more often than you'd think.
Power-Cycle Every Node in the Right Order
Unplug the main BT10 router. Unplug each AiMesh node. Wait a full 60 seconds with everything unplugged. Plug the main router back in and wait until the LED is solid white (about 90 seconds). Then plug each node back in one at a time, waiting 60 seconds between each.
This clears any radio state issue from a botched firmware update or an interrupted setting change. It's the single most effective fix for "the router is on but WiFi is gone."
Re-Enable Each Radio Band in the Web UI
Connect a laptop via Ethernet and go to router.asus.com. Log in with your admin credentials (the default is printed on the bottom of the router if you never changed it). Navigate to Wireless and check each band tab, 2.4 GHz, 5 GHz, and 6 GHz. Each tab has an "Enable Wireless Radio" setting. Make sure all three are set to Enabled, then click Save and Apply.
A common scenario is that one band got disabled during a firmware update or while someone was poking around in settings. Your phone sees nothing because it's trying to connect on 2.4 GHz, while your laptop happened to latch onto 5 GHz before the radio went quiet.
Turn Off Hidden SSID on All Three Bands
Still in the Wireless settings on each band tab, look for "Hide SSID." If it's set to Yes, the network is broadcasting but won't appear in normal WiFi scans on any device. Set it to No on all three bands and save.
This setting gets accidentally toggled surprisingly often, especially if you have multiple people in the house with access to the admin panel.
Disable MLO as a Diagnostic Step
Multi-Link Operation is the single highest-yield BT10-specific fix when SSIDs go missing. ASUS firmware release notes and user threads on SNBForums consistently point to MLO leaving radios in a half-on state after firmware updates. In router.asus.com, go to Wireless, then MLO, and set it to Disabled. Save and Apply, the router will reboot the radios.
If the SSIDs come back, you can leave MLO off for now. Very few Wi-Fi 7 clients actually benefit from it yet, and the stability trade-off isn't worth it. Re-enable later once you're on a newer firmware build where MLO is stable in your setup.
Check the Wireless Scheduler
ASUS routers have a per-band Wireless Scheduler that automatically turns radios off at set times. If someone in the household enabled it through the parental controls or the schedule settings, the BT10 will simply stop broadcasting at the configured time and look broken. Go to Wireless, then Professional, and check the "Enable Wireless Scheduler" setting on each band. Set it to No unless you're intentionally using it.
Verify the Country Setting
This one is rare on US-purchased units but worth a quick check. In Administration, then System, confirm that Country matches your actual location. A mismatch can disable specific bands by regulation, and the only symptom is that some or all SSIDs vanish.
Update the Firmware
Open the ASUS Router app on your phone. Tap Settings, then Firmware Upgrade. Install whatever is available. The MLO firmware (3.0.0.4.388 and later) introduced some radio-state quirks that subsequent versions addressed. The process takes about 10 minutes and the router and nodes will auto-reboot.
If the app can't connect because there's no WiFi, do the same thing from router.asus.com over a wired connection.
Check the AiMesh Topology
In router.asus.com, go to AiMesh. Verify that the main router is listed as the gateway and each node shows as connected. If a node is marked offline or is acting as the router instead of a mesh node, the broadcast can get confused. Tap any offline node and use the reconnect option, or remove and re-add it.
Factory Reset the Main Router
If you've gone through everything above and the SSIDs still won't appear, hold the reset button on the back of the main router for 10 seconds until the power LED starts flashing. This clears all settings back to factory defaults. Set it up again through the ASUS Router app or router.asus.com. Plan about 30 minutes, you'll need to re-add each AiMesh node one at a time during setup. The nodes are auto-discovered during the new configuration process.
