I am wondering if this router has been retired or EOL'd? There hasn't been a firmware update in almost a year.  I spent a small fortune on this beast yet it seems to have fallen by the side.  No really firm answer from TP-Link as to why.  They posted 1 firmware update a long time ago - it's why I am considering another different router such as ASUS OR Netgear for better support and letting my Archer BE 9300 become like the old Commodore 64 of it's day - a good doorstop.
