CIA Infection of Routers

There is not really much users can do. Router are always enjoying being a favorite target. I know my router is vulnerable to an exploit, Linksys promised a prompt firmware update, months ago, still waiting.

I prefer as dumb router as possible, the more advanced expensive router, the more exploitable it is.
Security precautions are recommended, always disable features, which you are not using, especially UPnP.
Change router's password and use 63-characters long WiFi password, all you have to do is to copy/paste it.
Setup DNS on your computer, it overrides router's DNS, so you can be protected in case of DNS hijacking.

I read the article on BleepingComputer's website a couple days ago, and had a look at the list of routers affected. They are all older models, so, not a risk unless your router is old and on the list.
