I am a big fan of open source operating system dd-wrt for routers. I have not bought a router in years that I did not immediately flash from the manufacturer's firmware to dd-wrt. It is a bit of a headache, but once done I get a router that is a lot more stable (I am also told that it is more secure, but I have no way to judge that). My router typically runs 6 months without rebooting with no issues, whereas with manufacturer firmware I sometimes have to reboot once a week to make it work.**
The FCC is considering new rules that may cause router manufacturers to lock out third party software like dd-wrt. The FCC is claiming that "illegally modified equipment" has interfered with doppler radar at airports. I find it very close to unbelievable that a hacked consumer router was interfering with doppler radar, and in fact the FCC did not specify what kind of equipment was illegally modified. As is usual, my guess is an agency is using a minute, niche problem in area A as an excuse for blanket, anti-consumer regulation in unrelated area B. You can sign an online petition to ask the FCC to rethink its approach here.
** To be fair I will add that dd-wrt, typical of a lot of third-party hacker products, is a lot less user friendly than a lot of modern router firmware. For my streaming system to work at home I have to lock a couple of servers down to a fixed IP address and this is a surprisingly fiddly task on dd-wrt.
