Yeah I was considering this actually, but then I realised that I really want a working LAN 100.0% of the time, so I'd only go tinker mode if I had a backup. So I was gonna be buying a router regardless.

Now I have a Ubiquiti one, it's antithetical to my DIY instincts but I think I'm OK with my router being one of the proprietary appliances in my life.

Plus now the wired section of my LAN is really fast.
