Is firmware always hardware dependent?
I purchased an AX3000 router and updated the firmware -Oh my!- TP-Link didn't update the wi-fi security protocols of the router!
That's why I ask: Is firmware always hardware dependent?
If it is not why new updates do not replace the weak wi-fi WPA/WPA2 (TKIP) by the more secure Wi-Fi Protected Access 2 (WPA2), or Wi-Fi Protected Access 3 (WPA3)?
I guess memory limitation is one of the reasons, but why not get rid of some less important features in order to make more room available? Or is the commercial interest much more important than the customer satisfaction?
