I’ve still got two MR3040. TP-Link hasn’t released any update for them in years. You can run an older version of OpenWrt on them, but there’s no real point. These things don’t even support 5GHz WiFi.

Device with very nice design. I still keep it as decorative even when its a brick.

I've got a few devices that only support 2.4 B/G. They're not in common use, but using an equally legacy router is the only way for them to connect.

2015 was also almost 10 years ago.

So i guess its a brick now and there is nothing we can do about it.

Using something that's already been produced (good) is not the same as selling dead end e-waste that's so underspecced it's barely working new (bad).

That thing was overstaying it's welcome for two years even then by staying on WiFi 4. 802.11n was adopted 15 years ago.
