A TP-Link Archer AXE75 that needs a firmware update, or whose update fails, can be updated from its web page or the Tether app, and the process needs a stable connection and a little patience. Connect a computer to the router by an Ethernet cable if you can, log in at tplinkwifi.net with your password, and open Advanced, System, Firmware Upgrade. The router checks online for a new version and shows its release notes; choose to update and wait without touching the router. Do not turn off the power during the update, which takes a few minutes and ends in a restart.
The checks in more detail
If you use the Tether app, open the router's page and look for the update notice. If the online check fails, download the file from TP-Link's support page for the AXE75, choosing the hardware version printed on the router's label, since the wrong version will not install. Unzip it and use the Local Upgrade option in the same menu to select the file. Back up your settings first from System, Backup and Restore, because some updates reset settings. After the update, check that Wi-Fi works, and that features such as the guest network and parental controls are as you left them.
If the update fails or the router will not respond, wait a few minutes, since it may still be writing. Restart it by switching it off and on once. If you cannot log in, hold the reset button for ten seconds to restore factory settings and set it up again. Enable automatic updates on the same page if you want them, but a manual check is safer for a router that holds your whole network. For a tri-band Wi-Fi 6E router such as this one, updates often include the 6 GHz fixes and security patches, so keep it current. Contact TP-Link with the hardware version if it will not take the update.
The AXE75 is a tri-band Wi-Fi 6E router, and TP-Link usually announces new firmware in the Tether app as a badge on the router. If the router reports that it is up to date but you know a newer file exists, the router's online check may be behind the website, so use the manual file. Check the file's version number against the one shown on the Firmware Upgrade page. After an upgrade, wireless devices may need a minute to reconnect, and smart home devices that cannot see the network can be restarted. If the router seems slower afterwards, restart it once and check that features like OneMesh remain enabled.
