@Philbert No, they're not. A cursory search for the TL-SG1048 shows that the mounting ears use 3-holes and not the standard 4-hole layout. That is why I am asking here.

I'm looking for mounting ears for this. I cannot find them, and contacting has not had much help. I'm in the USA. Is there a place to buy these, or is there something from another company that would...

@Kevin_Z I got the firmware from here: https://www.tp-link.com/us/support/download/archer-c1900/#Firmware It looks like there's only one version of the FW. Ideally I would like to install DD-WRT on it

Is there any way to load alternative firmware on this router? Even when I try to reload the factory firmware I get an error.
