@rogerwilker,

Firstly, I would recommend looking to see if you have the most up-to-date version for your firmware. According to the site, the most recent build for your router is Archer AXE75(US)_V1.6_220405. There have been multiple updates, one specifically addressing a TCL Roku TV connecting to the network.

If you are connecting via Wi-Fi 6E, you have to connect with WPA3, otherwise, the connection will fail. I do not know where this setting lies with a FireTV, however the option on the router can be found under the wireless settings, specifically for the 6Ghz band

  @rogerwilker,

You may not need to actually enable WPA3 on your FireTV, it may see the connection and switch encryption methods automatically.

This issue with FireTVs not being able to connect to a visible Wi-Fi network, and returning out of range, is actually not a new problem.

If you do some searching, this behavior can be seen on almost any FireTV device, but they were usually fixed by disabling smart connect or were related to an encryption incompatibility; which cannot really be done for the 6Ghz Band.

Have you already connected the device to your network, not on the 6Ghz band?

Try seeing if there is an update for your fire cube already, as it isn't uncommon to have a day-one firmware update.

I messaged you a guide that I had sent to a previous user that had the issue with a FireTv Stick.

  @rogerwilker,

Also, what hardware version do you have for your Archer Router, this can be found in the tether app or on the label on the bottom of the router. The firmware is different for each hardware version.
