Comment Flash FOSS firmware on used hardware. (Score 4, Interesting) 51
Many owners don't scrap replaced routers but sell them instead for next to nothing. Many of those are supported by OpenWrt, FreshTomato, OPNsense etc. Even if you replace an EOL router you can flash your previous hardware as a ready spare or do other useful tasks with it
For example I was satisfied by my old Netgear R6700v3 but bought a new GL-MT6000 out of curiosity, then flashed the Netgear with FreshTomato have a ready spare on the wall next to it. The only hassle was the buggy stock Netgear firmware demanded multiple login attempts which FreshTomato solved nicely.
You can go DIY with a wide variety of hardware including formerly expensive EOL network appliances, industrial PCs, used or new tiny form factor desktops and thin clients.
Rolling your own router/appliance has been easy since the single-floppy Linux router era at the turn of the century. Those enabled tasks like sharing my dialup connection using an old P75 with a Linux-compatible "hardware" modem before "Winmodems" were supported.
