Question 1

why does my archer ax73 randomly reboot itself once a day

Accepted Answer

DIAGNOSIS Faulty power supply or a scheduled reboot feature is enabled. Overheating can also cause this. FIX Check for a reboot schedule. Log in, go to Advanced > System Tools > Time Settings > Reboot. Disable "Enable Reboot" if it's on. Check the power adapter connection at both ends. Ensure the plug is fully seated in the router's DC-IN jack. IF THAT DIDN'T WORK Update the firmware. Go to Advanced > System Tools > Firmware Upgrade. Check for update. If none, perform a manual factory reset using the button. Set it up fresh without restoring old settings. HEADS UP If the router reboots during high network load, that points to a failing internal power regulator. Contact TP-Link support if under warranty.

Question 2

the wifi signal from my ax73 seems weak, doesn't reach as far as my old router

Accepted Answer

DIAGNOSIS Likely a transmit power setting or antenna orientation. The default transmit power is not always max. FIX First, orient the antennas correctly. Do not point them all straight up. Position two vertically and two at a 45-degree angle. Log into the router. Go to Advanced > Wireless > Wireless Settings. Set Transmit Power for both bands to "High". Apply. IF THAT DIDN'T WORK You might be on a crowded channel. Use the built-in scanner. Go to Advanced > Wireless > Wireless Statistics > Channel Utilization. See which channels are clearest. Manually set your bands to those channels. HEADS UP WiFi 6 (AX) signal strength bars on older devices can appear weaker because the measurement is different. Test actual speed, not just bars.

Question 3

i can't access my router settings at tplinkwifi.net anymore, page won't load

Accepted Answer

DIAGNOSIS Your device is not on the router's local network. You're trying to reach it via a disconnected WiFi or wrong IP. FIX Connect your computer directly to one of the router's LAN ports with an Ethernet cable. Open a browser and type 192.168.0.1 into the address bar. That should work. IF THAT DIDN'T WORK The router's IP might have changed. On a connected device, open command prompt. Type "ipconfig" (Windows) or "ifconfig" (Mac). Look for "Default Gateway". That IP is your router's address. Type that into your browser. HEADS UP tplinkwifi.net only works when connected to the router's WiFi. It does not work over the internet or a VPN.

Question 4

my archer ax73 gets really hot to the touch on the top, is that normal

Accepted Answer

DIAGNOSIS Yes, normal. This router has a large heatsink and no fan. It dissipates heat through the case. FIX Ensure proper ventilation. Do not place it on carpet, in a closed cabinet, or under other electronics. Leave at least 4 inches of clear space on all sides, especially the top vent. IF THAT DIDN'T WORK If it feels excessively hot—too hot to keep your hand on—check the power adapter. Use only the 12V/2.5A adapter it came with. A higher-amperage adapter can cause overheating. HEADS UP The case is designed to be warm. This is not a defect. Overheating would cause it to reboot or throttle performance, not just feel hot.

Question 5

how do i factory reset my tp-link ax73 if i forgot the admin password

Accepted Answer

DIAGNOSIS You're locked out of the web interface. A hardware reset is required. FIX Find the reset button on the back, near the ports. Use a paperclip. With the router on, press and hold the button for about 8 seconds. Release when all LEDs flash. Wait for it to reboot. Default login is admin/admin. IF THAT DIDN'T WORK If the reset button is unresponsive, perform a power-cycle reset. Unplug router. Hold reset button down. Plug router back in while still holding button. Keep holding for 10 seconds after power-on, then release. HEADS UP A factory reset wipes all settings, including your WiFi names and passwords. You will have to set it up from scratch again.

Question 6

the 2.4ghz wifi on my ax73 is super slow but the 5ghz is fine, what gives

Accepted Answer

DIAGNOSIS The 2.4GHz band is congested or a setting is throttling it. Neighbor networks and Bluetooth devices cause major interference. FIX Change the 2.4GHz channel width. Log in, go to Advanced > Wireless > Wireless Settings. For 2.4GHz, set Channel Width to 20MHz, not 20/40MHz. Choose Channel 1, 6, or 11 manually. Apply. IF THAT DIDN'T WORK Smart Connect might be misdirecting devices. Disable it temporarily. Go to Advanced > Wireless > Wireless Settings. Uncheck "Enable Smart Connect". Set separate SSIDs for 2.4GHz and 5GHz. Connect slow devices to 2.4GHz SSID directly. HEADS UP 2.4GHz will always be slower than 5GHz on this router. That's normal. Its purpose is range, not speed, for things like smart plugs.

Question 7

just got an archer ax73 and the internet light is solid orange, no internet

Accepted Answer

DIAGNOSIS The router is not getting a valid IP address from your modem. The WAN port link is good, but authentication failed. FIX Power cycle the whole chain. Unplug the router and modem. Wait 60 seconds. Plug in the modem, wait for its lights to stabilize. Then plug in the router. Use the short Ethernet cable from the box to connect modem WAN to router WAN port. IF THAT DIDN'T WORK Your ISP might require MAC address cloning. Log into the router. Go to Advanced > Network > Internet. Set Internet Connection Type to your ISP type. Look for a "Clone MAC Address" option. Enable it. Save and reboot. HEADS UP A solid orange Internet light means a physical link but no data. If it's flashing orange, that's a different problem—the cable or port is likely bad.

Question 8

my archer ax73 router keeps randomly dropping wifi for a few seconds and then coming back, especially on my 5ghz band

Accepted Answer

DIAGNOSIS This is classic 5GHz DFS interference. The router is detecting radar signals and switching channels automatically. FIX Log into the router's web interface. Go to Advanced > Wireless > Wireless Settings. Change the 5GHz Channel to a fixed, non-DFS channel. Choose 36, 40, 44, or 48. Apply the settings. IF THAT DIDN'T WORK The issue might be a firmware bug. Go to Advanced > System Tools > Firmware Upgrade. Check for a newer version. Update if available. Reboot after. HEADS UP Using a fixed channel can reduce performance in congested areas. Letting it use DFS channels is usually better if radar isn't present in your location.
